Caps, Screw Top, Solid, with a 0.2mm thick, PTFE only liner, in "knurled", closed Blue Caps. For use with 9-425mm thread, 12x32mm autosampler vials. MicroSolv Brand. 100/PK.

Additional Info:

PTFE is a very inert material for liners and is compatible with most chromatography samples and solvents. However, PTFE can be minimally porous and does not offer the same sealing capabilities as a Rubber / PTFE liner may provide. This cap is very useful for storage of non-volatile samples.

These solid polypropylene, blue caps turn autosampler vials into storage vials.
