basic requirements in each of these methods has beencarefully reviewed, andextensive testing has confirmedthat the results obtainable withthese calorimeters will meet orexceed the repeatability andreproducibility limits specifiedin these test methods.

With all the changesthat have taken placein our first century of

designing, buildingand servicing

calorimeters, onething has not changed— our commitment tobuild the best practi-cal calorimeters is asstrong today as it was

when our companywas founded for that

same purpose.

temperature of the bomb andbucket rise as heat is releasedby the combustion. In thisimplementation, a water jacket,maintained at a fixed tempera-ture, completely surrounds thecombustion bomb and its“bucket”. A microprocessor-based controller monitors boththe temperature of the bucketand the jacket and performs the necessary heat correctionsthat result from differences in these two temperatures.These corrections are appliedcontinuously rather than as afinal correction based on preand post test measurements.



Removable bomb calorime-ters are the more tradition-

al design most users recognize.In this design the oxygen bomband bucket are removed fromthe calorimeter for loading thesample and filling the bucketwith the carefully measuredamount of water which absorbsthe energy released in thecombustion.

RecommendedApplications

While these bombs do notfeature the automatic bomband bucket handling featuresof the fixed bomb designcalorimeters, the removablebomb calorimeter will remainthe calorimeter of choice forusers with one or more of thefollowing applications orpreferences:• Low to medium testing loads

which will not justify thehigher cost of more auto-mated systems.

• Student instruction applica-tions with an emphasis onthe basic principals ofcalorimetry.

• Applications which requireunusually high pressures,platinum lining or one of theother special purpose oxy-gen bombs.

• Combustions which produceunusual amounts of ash orother corrosive residues thatwould damage the automat-ic discharge system.

• Users who chose not to perform the additional main-tenance that the fully auto-matic instruments require.

• Users who presently havea number of 1108 oxygenbombs and other acces-sories in their laboratories.


P a r r I n s t r u m e n t C o m p a n y6

Parr Model 6300 Calorimetersutilize a design where the

bomb and bucket are notremoved from the calorimeterduring routine operations. This concept has made it possi-ble to provide new levels ofautomation of not just the datacollection and reporting, but of the entire calorimetric determination.

Bomb ClosureThe 6300 Calorimeter utilizes

a patented closure designwhich seals and locks the headinto the cylinder with simple 23° twist.

Measuring and Filling theCalorimeter Bucket

The bomb in the 6300Calorimeter is surrounded by a bucket designed to providesmooth circulation and uniformvolumetric filling. The bombhead closure action also sealsthe bucket at the same time the bomb is closed. The uniquedesign of this bomb-jacketcombination permits rapid andautomatic volumetric filling ofthe “bucket” water for each test.

Oxygen Filling The oxygen supply is con-

nected to the fixed bomb sothat the oxygen charge is auto-matically added to the bombbefore the preperiod equilibri-um period.

Exhausting the BombAt the end of the test the

gasses in the bomb are auto-matically released while thecalorimeter is being returned to its starting temperature.

Draining the BucketThe hot water in the bucket

is automatically drained fromthe bucket at the conclusion ofthe test and replaced with cool-ing water to bring the bomband bucket rapidly back downto the starting temperature forthe next test.

Washing the BombAt the conclusion of the

test the inside of the bomb iswashed to remove the productsof combustion from the bomb.These bomb washings can becollected if tests will be run forsulfur, chlorine or other ele-ments released from the organ-ic matrix during combustion.The result of the automation of the above steps plus theautomation of the calorimetricmeasurement itself will saveapproximately six minutes ofoperator time per tests whencompared to any removablebomb calorimeter.

Parr Fixed Bomb & Bucket Technology

Longer Bomb Life

One of the not so obvious advantages ofthe fixed bomb designs is that the bomb is

always washed as soon as the final temperaturerise can be extrapolated. Generally this is within4-5 minutes of the firing of the bomb. This minimizes the time any acids produced by thecombustion can attack the inner surfaces of the bomb. We are seeing much better servicelife for the 1136 Bombs used in corrosive service because of this.

Parr Removable Bomb & Bucket Technology

Materials of Construction

In 1911 Professor S.W. Parr developed his Alloy Illium G to resist the hotmixtures of sulfuric and nitric acids produced in the oxygen combustion

of coal. This eliminated the need for gold or platinum liners for the bombsand made it practical to do oxygen bomb calorimetry as a routine labora-tory test. While we no longer use Illium G, we use the most corrosionresistant alloys we can find. For routine combustions we build our bombsof Carpenter 20 Cb3 Stainless Steel which is richer in chromium and con-tains three times as much nickel as Series 300 Stainless Steels. For highchloride service we use Alloy G-30 which adds cobalt and molybdenumto resist the corrosive effect of the chloride ion.

Parr is pleased to introducewith this catalog its new

Series 6000 line of OxygenBomb Calorimeters. This newline includes five differentOxygen Bomb Calorimeterswhich continue Parr’s traditionof offering the widest choice ofinstruments to the world’s fueltesting and research laborato-ries.

Bomb Calorimeters

The Model 6300 AutomaticIsoperibol Calorimeteroffers the world’s most auto-mated calorimeter featuring thefixed bomb and bucket design.This calorimeter builds on theten years of experience gainedwith the earlier Model 1281Calorimeter.

The Model 6200 IsoperibolCalorimeter represents thecurrent development of the tra-ditional removable bomb andbucket calorimeter. Thiscalorimeter is the updated ver-sion of the earlier Models 1266,1261, and 1241 which havebeen the world’s most popular.

We continue to offer theModel 1341 Plain JacketOxygen Bomb Calorimeter.This instrument provides safeand reliable testing with tradi-tional thermometry at a mini-mum capital investment.

The new Model 6725Semimicro Oxygen BombCalorimeter offers a high degreeof electronic automation and con-trol for users who prefer or mustwork with small samples. Thiscalorimeter replaces the earlierModel 1425 Calorimeter.

The Model 6100Compensated JacketCalorimeter utilizes Parr’sreal time thermal correctioncapabilities to provide aninstrument for rapid testingwith good repeatability at avery attractive price. Thiscalorimeter replaces earlierModels 1356 and 1351Calorimeters.

Isoperibol CalorimetryAn isoperibol calorimeter is

one where the surroundingjacket is maintained at a con-stant temperature while thetemperature of the bomb andbucket rise as heat is releasedby the combustion. The Model6300 and 6200 Calorimetersare true isoperibol calorime-ters. In these implementations,a water jacket, maintained at afixed temperature, completelysurrounds the combustionbomb and its “bucket”. Amicroprocessor-based con-troller monitors both the tem-perature of the bucket and thejacket and performs the neces-sary heat leak corrections thatresult from differences in thesetwo temperatures. These cor-rections are applied continu-ously throughout a test ratherthan as a final correction basedon pre and post test measure-ments.

ContinuouslyCompensated IsoperibolCalorimetry

The Parr 6100 Calorimetertakes advantage of the realtime, continuously correctedmethod developed by Parr inits implementation of theisoperibol method. No attemptis made in the Model 6100Calorimeter to establish theconstant jacket temperaturerequired for isoperibolcalorimetry. Instead, the tem-perature of the jacket is contin-uously monitored and real timeheat leak corrections areapplied based upon the tem-perature difference betweenthe bucket and the actual temperature of the jacket.While this method is not trulyan isoperibol method, its realtime correction procedureachieves the same purposewith nearly equal results. What it can not do is match the temperature uniformity of a circulating water jacket.

Compensated IsoperibolCalorimetry

The Parr 6772 PrecisionThermometer, serving as acontroller for the 1341 or 6725Calorimeters, uses yet anotherapproach to emulate theisoperibol calorimetric method.In these calorimeter systems,the heat leak is precisely mea-sured during the calorimetricpre-period. This evaluationresults in an estimate of theeffective, average temperatureof the calorimeter surround-ings. This temperature valueis then used throughout thetest interval to provide thecalorimeter heat leak correc-tion. While not as robust aseither of the other two methodsoutlined above, it harnessesthe computing power of thecontroller, with no additionalhardware costs, to provide heatleak correction capability that is almost identical to theapproach used when non-electronic thermometry andmanual calorimetric techniquesare employed.

Parr Fixed Bomb andBucket Technology

The Model 6300 Calorimeterutilizes the proven fixed bomband bucket technology utilizedin Parr 1271 and 1281 Calori-meters for more than 10 years.This design concept has madeit possible to offer unique lev-els of automation of the entirecalorimetric determination notjust the data collection andreporting steps.

Fixed BombsInstead of removing the

entire combustion bomb, open-ing it, washing it, rechargingit and reinstalling it in thecalorimeter, the operator simplyremoves the head of the vesselreplaces the fuel capsule withthe next sample and fuse andreinserts it in the calorimeter. A patented closure designwhich seals and locks the headin place with a simple 1/16 turnmakes the removal and installa-tion of the head quick and easy.

Fixed BucketConventional calorimetric

terminology refers to the vesselwhich contains the bomb and aknown amount of water in thebucket. In the 6300 Calorimeter,a better description might be awater jacket for the bomb. Thisinner jacket has been designedto provide smooth circulationover the surfaces of the vesseland highly repeatable volumet-ric filling. The bomb head clo-sure also seals this water jacketat the same time the bomb isclosed. This unique design

minimizes the amount of waterrequired as well as permittingrapid, automatic and repeatable“bucket” filling for each test.The water heated by the com-bustion is automaticallydrained from the bucket atthe conclusion of the test andreplaced with cooling waterto bring the bomb and bucketrapidly back down to thestarting temperature for thenext test.

Oxygen Charging andRelease

The oxygen supply is con-nected to the fixed bomb andoxygen charging to the desiredlevel is automatically performedat the beginning of each test. At the end of the test the gasesin the bomb are automaticallyreleased while the calorimeteris being returned to its startingtemperature.

Bomb WashingAt the conclusion of the test

the inside surface of the bombis washed to remove the prod-ucts of the combustion fromthe bomb. The automation ofthe bomb washing step elimi-nates one of the most tediousand time consuming manualoperations required withremovable bomb calorimeters.The bomb washings can becollected if they are to be usedfor tests to determine sulfur,chlorine, or other elementsreleased from the organicmatrix during the combustion.Besides the elimination of thedrudgery of manually washingthe bomb, a not so obviousadvantage of the fixed bomb

design is that the bomb isalways washed as soon as the final temperature can bedetermined. Generally, this iswithin 4-5 minutes of the timethe bomb is fired. This holds toan absolute minimum thetime any acids produced by the combustion can attach tothe inner surfaces of the bomb.We have observed much betterservice life of these bombs incorrosive service when com-pared with removable bombs.

6300 Automatic Isoperibol Calorimter


An important design conceptof the 6300 Calorimeter is tofree it from the requirementto use a number of accessoriesthat add significantly to thecost of the instrument.

Water SupplyThe 6300 Calorimeter has

been designed to operate withtap water as its principal sourceof water for filling both the“bucket” and the outer jacket.This water also serves as thesource of cooling for the bomband bucket between tests.

Users who have poor qualitytap water or who do not haveaccess to running water and adrain can add a Model 1564 or6520 Water RecirculatingSystem and operate thecalorimeter on a closed loopwith de-ionized water. Thisinstallation requires that theWater Recirculating System be installed below the 6300Calorimeter so that the waterfrom the calorimeter can drainby gravity. All closed loop sys-tems require a water cooler toremove the heat generated bythe combustion from the system.

Deionized or distilled wateris highly recommended for thebomb wash water supply. Evenusers who will not recover thebomb washings for furtheranalysis will want to avoid theproblems that can result fromthe build up of lime deposits inthe oxygen combustion bomband its valves.

Compact Design — The 6300 Calorimeter is

housed in a compact case 16.5inches wide, 15.5 inches deep,and 17.0 inches high (42 x 40 x43 cm). The units require asupply of tap water, a drain,115 or 230 volt power and a

supply of oxygen. Users whowish to use their washings foranalytical purposes will alsoneed a supply of de-ionizedwater.

Dual Bomb and BucketOperation

Users with large testingrequirements can equip their6200 calorimeters with twobombs and two buckets so thatone set can be reloaded whilethe current test is underway inthe calorimeter.

True Isoperibol OperationAs with the Model 6300

calorimeter, all of the surfaceswhich surround the innerchamber of the 6200 calorime-ter are controlled to a constanttemperature from a circulatingwater bath. This enables thecontrol section of the calorime-ter to both determine the heatleak corrections and applythem in real time. This combi-nation makes it possible tooperate the calorimeter inParr’s dynamic mode for rapidtesting without a detectable difference in the precision ofthe test.

Open or Closed LoopOperation

The 6200 calorimeter canbe operated on an open systemwhere tap water is used both to cool the jacket and to fill thebucket. This minimizes theneed for a separate water han-dling system and cooler andwill also minimize the capitalinvestment. Users with signifi-cant testing loads or poor qual-ity tap water will want to adda Model 1564 or 6520 WaterHandling System (see page 23)and operate with deionized,temperature controlled, andpre-measured water.

Oxygen Filling SystemTo speed and simplify the

bomb filling connection, the6200 Calorimeter has aSemiautomatic system forcharging the bomb with oxy-gen. Oxygen from a 1A com-mercial cylinder is connected to a micro-processor controlledsolenoid installed in thecalorimeter.

To fill the bomb, the opera-tor simply slips the filling hoseconnector onto the bomb inletvalve and pushes a key to startthe filling sequence. Fillingthen proceeds automatically at a controlled rate to a pre-setpressure. Built-in safety provi-sions will prevent an accidentalovercharge, and an error mes-sage will be shown if the de-sired pressure is not attained.

Compact DesignThe 6200 calorimeter is

housed in a compact case 22.5 inches wide, 15.5 inchesdeep and 17.0 inches high(57x40x43 cm).

The units require a 115 or230 volt electrical supply, tapwater and a drain (or a waterrecirculationg system) and asupply of oxygen.

Removable BombThe Model 6200 calorimeter

utilizes the Parr 1108 oxygenbomb. More than 20,000 ofthese reliable oxygen combus-tion bombs have been placed in service on a world widebasis. This bomb features anautomatic inlet check valve andan adjustable needle valve forcontrolled release of residualgasses following combustion.They are intended for samplesranging from 0.6 to 1.2 gramswith a maximum energy releaseof 8000 calories per charge.

The 1108 oxygen bomb ismade of a high-strength, high-nickel stainless steel designedto resist the corrosive acidsproduced in routine fuel test-ing.

A Moderately Priced,Micro-Processor ControlledOxygen Bomb CalorimeterWithout JacketTemperature Control

Outwardly, the 6100Calorimeter appears to be thesame as the 6200 IsoperibolCalorimeter, since bothcalorimeters are built into thesame housing with the sameseries 6000 controller. But,there is one important differ-ence: the 6100 Calorimeterdoes not have a temperaturecontrolled jacketing system asrequired for isoperibolcalorimetry. The 6100Calorimeter is intended for theuser who wants a moderncalorimeter with the convenientautomatic features provided inthe 6200 Calorimeter andwhose precision requirementscan be met with a static systemwithout isoperibol control. Or,for users whose work load issmall or intermittent, making itpreferable to purchase a lessexpensive model. To meetthese criteria, the temperaturecontrolled water jacket and itsaccessories have beenremoved from the 6200Calorimeter and replaced in the6100 with an insulating jacketaround the bucket chamber,comparable to the arrangementused in the 1341 PlainCalorimeter. This eliminates allwater and water connections,resulting in a significant savingin cost. And, with no perma-nent external connections(except a connection to an oxygen tank). The 6100 Calori-meter can be set up and madeready to operate in a few minutes, or it can be set asidewhen not in use.

Good RepeatabilityTo obtain the best precision

with an uncontrolled jacket, the6100 Calorimeter has a temper-ature monitoring capabilitybuilt into the jacket. This allowsthe calorimeter to measure theactual jacket temperature andapply the appropriate heat leakcorrections in real time. Whilenot equal to a controlled jacket,the 6100 method offers a signif-icant improvement over the tra-ditional static jacket and makesit possible to obtain reasonableprecision without the long pre-and post-periods normallyrequired for static jacketcalorimetry. It also makes itpossible to use the ParrDynamic Method for rapid test-ing. As with all static jacketcalorimeters, best results willbe obtained when the calorime-ter is operated in a locationwhere it is not subject to drafts

A Reliable Oxygen BombCalorimeter In A Plain InsulatedJacket for Occasional CalorificTests

The 1341 Calorimeter is the currentversion of a plain, static jacket, oxygenbomb calorimeter that has been madeby Parr for more than eighty years. It isa reliable calorimeter that can be usedfor the same broad range of solid andliquid combustible samples as theseries 6000 models. Its modest costand simple design recommend it pri-marily for users whose work load doesnot justify the purchase of an automat-ic model. The calorimeter requires nopermanent connections. It can be setup and ready to operate in a few min-utes and, when not in use, can be easi-ly disassembled and stored on a shelf.

Many ApplicationsThe calorific value of any solid or

liquid material that can be burned safe-ly in an oxygen bomb can be deter-mined in the 1341 Calorimeter. It is alsoan excellent instrument for teaching

heat measurement techniques in a student laboratory since it provides allof the instrumentation needed for suchtests, but with each element in the system reduced to fundamental forms.Although commonly called a “plain”calorimeter because of its simpledesign, technically this is a static jacketinstrument which operates at or nearroom temperature with no provisionfor controlling the jacket temperature.Compensation for any heat loss (orgain) during a test is made by applyinga correction computed from heat leakmeasurements taken before and aftereach test. As a general rule, about 10or 12 tests can be completed in an 8-hour day, whereas up to 75 tests can be run in the same period in a Parr automatic model.

Good RepeatabilityGood repeatability can be obtained

with the 1341 Calorimeter providedthat the temperature rise and heat leakcorrections are measured and appliedcarefully. Using the 19-35 °C expansionthermometer supplied with the instru-ment, standard deviations in a series of tests with a uniform sample such asbenzoic acid should not exceed 0.3%.

Quality ConstructionThere has been no compromise with

quality in selecting components for themoderately priced, 1341 Calorimeter. It is equipped with the same 1108Oxygen Bomb furnished with the 6200Isoperibol Calorimeter. An alternate1108CL bomb with superior resistanceto chlorine and halogen acids is avail-able for tests involving waste materialsand chlorinated solvents. The moldeddouble wall jacket provides a simpleyet effective insulating system thatrestricts heat flow between thecalorimeter and its surroundings.Temperature readings are taken witha 1604 Calorimetric Thermometer witha range from 19-35 °C in .02° subdivi-sions. Readings can be estimated tothe nearest .002° using the clip-on read-ing lens furnished with the instrument.

1104 High StrengthBomb. This is a 240mL, extraheavy bomb for combustiontests with samples that burnwith extreme violence. It willhandle samples that liberate upto 12,000 calories per charge,using oxygen charging pres-sures up to 45 atm. This bombshould be used in place of thestandard bomb when testingexplosives, gun powders andfast-burning propellants, orwhen working with materialswhose combustion characteris-tics are unknown or unpre-dictable.

The 1104 High PressureOxygen Bomb can also beequipped with a dynamic pres-sure recording system to recordthe change in pressure thataccompanies the rapid decom-position of materials used aspropellants or explosives.

1105C Platinum LinedBomb. This is a 340mL Bombwith a full platinum lining forapplications requiring a com-pletely inert combustion cham-ber for analytical applications.All normally exposed inner sur-faces are covered with plat-inum, and the electrodes, inlettube and other metal fittingsare made of platinum alloyedwith 10% iridium for extrastrength. Platinum fuel cap-sules and fuse wire are used tocomplete an all-platinum envi-ronment.

The 1108CL Chlorine-Resistant Bomb

Parr now offers a chlorine-resistant, 1108CL Bomb, whichis the same as the standard1108 model, but with a headand cylinder made of an alloywith superior corrosion resis-tance to the free chlorine andhalogen acids released whenburning chlorinated samples.Users who intend to test wastematerials and combustiblehalogen solvents are urgedto select the 1108CL Bombinstead of 1108 for its longerservice life under extremelycorrosive conditions.

The 1136 OxygenBomb

The 1136 OxygenBomb is a customdesign bomb used inthe 6300 calorimeteras well as the earlier1281 Calorimeter. Itwill safely burn sam-ples liberating up to a maximum of 8000calories per chargeusing oxygen charg-ing pressures up to 40 atm. It features the twist-lock closureand the external configuration used in the fixed bombcalorimeters.

The standard 1136bomb is made ofalloy 20 Cb3 stainlesssteel to resist themixed nitric and sul-furic acids producedin routine fuel testing.

More than 20 years agoParr developed and

equipped its calorimeters witha local area network called the“Smart Link”. This network has served our clients well andhas given them a way to linkmultiple calorimeters, analyticalbalances, proximate analyzers,and computers into a singlenetwork.

With the Series 6000Calorimeters we are retiring the old and limited Smart Linknetwork in favor of Ethernet(IEEE 802.3). Ethernet hasbecome the standard for highspeed data transfers. While wefeel nostalgic for the “SmartLink” which was revolutionarywhen it was introduced, we arepleased to be able to offer theEthernet as a modern highspeed, reliable, industry stan-dard for linking instrumentsinto data transfer networks.

Direct ConnectionEach Parr Series 6000

Calorimeter is equipped withRS232C data ports. One ofthese is configured for a con-nection to an analytical balanceused for inputting sampleweights. The operating menusallow user to configure thisport for any commercial balances communications protocol.

The second port is config-ured to report results to anattached printer. While thedefault settings configure thisport for use with the Parr 1757Printer, the operating menusallow the user to configure this port for any 40 or 80 col-umn printer.

The third port is a terminalport and is used for diagnosticsand to input program updates.

Ethernet CommunicationsConnections of Series 6000

Calorimeters or personal com-puters and networks are madethrough the Ethernet Port.

Laboratories that alreadyhave Ethernet network installedcan simply connect theircalorimeters to their networkto transfer results into theircomputers.

Laboratories that do notalready have Ethernet networkwill need to obtain an Ethernethub to establish their network.Modern PC’s have both thephysical Ethernet port and thehigh-level protocol softwaresuch as TCP/IP required foroperation of this network.

The Technical ServiceDepartment at Parr will behappy to help with any ques-tions you may have regardingthis network.

Compact Flash TransfersParr Series 6000

Calorimeters are also equippedwith a port for a removablecompact flash memory card.This card can be used to transfer data files from thecalorimeter to a computerusing a simple card readerof the type used for digitalcameras.

The compact flash port canalso be used to update the soft-ware in the calorimeter.

Legacy SystemsUsers currently using the

Parr “Smart Link” networkshould contact the ParrTechnical Service Departmentfor the latest information oncombining the Smart Link andEthernet networks.

Pellet PressThe Parr Pellet Press provides a convenient and inex-pensive means for compressing powdered samples into

pellet or tablet form foroxygen bomb calorimetry.Although many materialsburn well as a loose pow-der, others such as benzoic acid must be pelletized for safe andcomplete combustion.

Pellets produced in theParr press are cylindrical

in shape with flat ends. Punch and die sets are inter-changeable in the same basic press. The 1/2 inch sizeis most commonly used for bomb calorimetry.
