Soft-Guard™ Septa - Easy to Pierce - Improved Resealing

Soft-Guard™ 11mm snap top caps with a bonded, silicone rubber (white) & PTFE (red) pre-slit septa are compatible with most 11mm, 12x32mm, 2ml screw thread vials in HPLC, LCMS, GC or GCMS.

The silicone rubber and PTFE liner used in Soft-Guard™ caps were designed to provide the right amount of resistance to autosampler needles during the injection process so that they penetrate the vial properly without damaging the septa or the injection needle. Too much or too little resistance to the needles can damage the septa, compromise resealing, cause needle blockage from coring of the septa material and even damage your autosampler. These septa perform even when using a wide range of needles: fine, blunt or even dull. Low sample or solvent evaporation performance even after multiple injections have been observed when using Soft-Guard™ caps.

This dark blue, polyproylene cap has smooth exterior sides for easy snap and comfort when applying or removing the cap for proper sealing. Color is useful for easy identification of samples, users or dates.
