Oct 21, 2022 · Oct. 21st, 2022. The septa and vial caps are essential parts of HPLC vials. The vial cap serves as a barrier, keeping outside contaminants out of the vial and preserving the integrity of the sample. The septa, a seal between the injection needle and the vial composed of silicone, PTFE, or rubber, ensure accurate and exact sample injection.
Septa for use with general chromatography vials. PTFE/Red Rubber Septa: (PTFE/RR) PTFE/Red Rubber septa are the most popular and economical choice for general gas chromatography applications. These septa are used primarily for routine analysis in gas chromatography with FID, TCD and FPD detectors. PTFE/Red Rubber offers moderate resealability
The preslit PTFE/Silicone septa exhibit excellent resealing properties and are advised for repeated injections and sample preservation. A working temperature range of -40 °C to 200 °C is available. You may also be interested in the Solid Cap for 22 mL Vial, PTFE/Silicone Liner, 100/pk.
For applications involving automated transport of vials, magnetic caps are recommended. The cap liner or septa is the part of the cap which establishes a tight seal with the vial. Liners and septa can be laminated with PTFE on one or both sides, which results in high chemical resistance and a nearly inert barrier between sample and septa material.
Chemglass. Replacement septa for use with MW-102 open-top screw caps on Minum-Ware® glassware components. Septa are made of silicone rubber with one side having a RED PTFE face, while the opposite side has an ultrathin covering of polypropylene to prevent needle coring when penetrating septa.

The septum is provided with a thin 0.005” PTFE layer laminated to highly pure silicone, and slit through the center for easier needle penetration and to release the vacuum that forms when a large volume of sample is withdrawn from a vial.
A specially moulded seal with a PTFE insert. Sealing surface of Butyl and PTFE affects a more positive seal than non-PTFE-faced septa. Ideal choice for temperatures below 125°C. Good sealing characteristics, excellent resistance to most solvents with reduced coring and high puncture tolerance.

Advances in glass vial manufacturing now produce the type of threads that are needed to properly seal the vial and cap under pressure, producing a Screw Top Headspace System that works well together. Different cap styles such as magnetic caps, pressure relief caps, and standard crimp caps are available. *We offer almost every type of septa
Screw caps are available as hole caps for use with sealing septa and solid caps with aluminum or PTFE liners. Caps are offered in polypropylene or phenolic resin. Polypropylene caps have a maximum temperature of 135° C while phenolic hole caps have a maximum temperature of 149° C and solid phenolic caps have a maximum temperature of 205° C.
Sep 28, 2015 · The septa are formed from 2 layers. The PTFE is on the lower side that faces your sample in the vial and is relatively inert to solvents. The top side is red coloured rubber or a silicone that helps to make the seal with the cap on crimping. In general the Rubber/PTFE septum is fine for general use for 1 or 2 injections within a short space of
