Never worry again about burned fingers or having to wait for the injector to cool down. The Hot Swap capillary column nut allows you to change your capillary column while the injector temp is still hot.

The Claw safely and cleanly removes liners, O-rings, or other small objects from the hot injection port.

Easily remove the liner from the hot injector with our high-temperature silicone Inlet Liner Removal Tool.

No More Burned Fingers

Finger-tight capillary column nuts are an excellent alternative to conventional column nuts. They can be installed by hand without a wrench, and they cool down much faster than conventional fittings, making column and inlet maintenance easier.

Available with CGA, BS, or DIN fittings.

Restek Porous Polymer Columns Cover a Wide Range of Polarities• The manufacturing process for porous polymer PLOT columns

causes particles to adhere strongly to the walls of the tubing, so there is virtually no particle generation.

• You get reproducible performance from column to column, including selectivity and flow.
