Whatman GD/X syringe filters

The GD/X filter contains a unique prefiltration stack of 100% borosilicate glass. Theprefilter will retain fine particles down to 0.7 m, allowing difficult sample filtrationwith less hand force. The volume of the sample filtered is 3-7 times greater than anunprotected membrane. PP housing. Syringe filters can be autoclaved.

Membranes:

Cellulose Acetate: for biological solutions, high-loading capacity, and low-protein-bindingNylon: for aqueous and aqueous organicsPolyethersulfone: for serum, plasma, and tissue culture solutionsPolypropylene: high flow for aqueous and organicsPolysulfone: low-protein-adsorption for serums and plasmaPTFE: chemically inert, will stop aqueous aerosols in gas streamsPVDF: the most suitable membrane for HPLCGlass microfiber: borosilicate with high-load capacity

Laser Cryo-Tags

Label large numbers of 1.5 mL or 2 mL microcentrifuge tubes with theconvenience and automation of word processing. Chemically inert labels adheretightly and withstand autoclaving, freezing, most organic solvents, and caustics.Sheets are specially top-coated to accept laser printing. Thin film and non-migrating adhesive mean that labeled tubes will not bind in centrifuge rotor.

Tough-Tags microcentrifuge tube labels

Tough-Tags are chemically inert polyester labels that strongly adhere to all plasticsand other materials. They are temperature resistant from 121C to 40C. Theselabels will withstand autoclaving, boiling water baths, freezer temperatures,organic solvents, caustic agents and other challenges without peeling, cracking orfalling off. For best adhesion it is recommended that siliconized surfaces beavoided.Tough-Tags are pre-cut, peel-off labels which accept any markinginstrument and are perfectly sized to fit microcentrifuge tubes and othercontainers in the laboratory. Tubes with Tough-Tags wrapped around them willstill slide easily in and out of rotors without binding because the labels are thin andthe adhesive does not migrate from behind the label even after boiling andautoclaving.pkg = 1,000 ea
