contaminate the sample. To prevent coring : • Choose a PTFE-lined septum to prevent sample contamination • Make sure the needle is not damaged and consider a side-entry instead of conical needle • Use pre-slit septa which will eliminate coring Vacuum Generation Sometimes withdrawing volume from a sealed vial can create vacuum.

Description. Prevent septa push through and over- and under-tightening. With Advanced Vial Closure System (AVCS) technology built into 9 mm Thermo Scientific™ 9 mm Autosampler Vial Screw Caps and Septa you will get an optimal, consistent seal every time. With just one turn, they offer easy-on, easy-off convenience, and are a cost effective
make PTFE/silicone septa suitable for all types of chromatographic applications. A thin film of PTFE is laminated to the side of the septum that faces the sample to limit exposure of the elastomer to the solvent. PTFE/Silicone septa are ideal for use in most HPLC and GC applications where resealability and purity are critical. Pre-slit PTFE
PTFE-faced silicone rubber septa are autoclavable, resist coring, and are recommended for use in all autosamplers using screw thread vials. Septa and liners can be laminated with PTFE on one or both sides to provide high chemical resistance and a nearly inert barrier between sample and septa material.
Pre-slit PTFE/Silicone Septa: A PTFE/Silicone septum is provided with a thin 0.005” PTFE layer laminated to our high purity silicone and slit through the center to provide for easier needle penetration as well as to release the vacuum that forms when a large volume of sample is withdrawn from a vial. This septum provides chromatographic
Content. Aijiren produces matching Closures for HPLC Vials, especially Septa, which is made of Silicone and PTFE. Septa can ensure that the hplc vials are sealed. At the same time, it must ensure that the automatic injection needle can penetrate into the interior of Vias for sampling, so for Septa There are certain requirements for the thickness.
