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.

The NR Series of Natural Rubber liners and septa are designed for high performance and economy. Manufactured from a high quality custom developed compound (5652), these Natural Rubber products exhibit good re-sealability, very good chemical resistance and can withstand temperatures up to 100 o C. Natural Rubber septa work particularly well with organic solvents and are most commonly supplied

Mar 31, 2022 · When comparing red and black rubber septa, one thing comes to mind. Black rubber septa are molded from a higher density rubber compound compared to the red one. This septum has characteristics like the gray butyl stopper. But, the difference is with a smaller temperature range of –20 to 100°C. The Black Rubber septum is an affordable choice.

Septa might release different substances that are detected during sample analysis. Additionally, the emission of contaminations can interfere with the investigated or potentially important compounds. Septa are typically made of butyl rubber or silicone. Butyl rubber is airtight and seals well . This polyisobutylene polymer consists of 98% of

Black Rubber Septa: (C4020-40) Black Rubber septa are molded from a higher density rubber compound compared to the standard red rubber. This septum has characteristics similar to the Gray Butyl stopper. The Black Rubber septum is an economical choice for applications where reduced levels of vapor penetration are desired.

Septa. Cap number and hole diameter given in listings. Tuf-bond Septa (9711D10 to D45) Thickness: 100 mils Of silicone rubber with PTFE facing 10 mils thick Septa of butyl rubber, silicone rubber or rubber-laminated PTFE are available on special order. Septum diameter indicated in listings.

General Purpose Septa for GC. Aijiren’s general-purpose septa are made from an enhanced injection-molded silicone rubber material. The septa material, dark red or gray in color, is specified to withstand over 200 automatic injections at an injection port temperature of 350 °C. You can have confidence in your chromatographic results knowing

DURAN® Bromobutyl Rubber Stopper, for GL 25 or GL 45 Laboratory bottles DURAN® PTFE-coated Silicone Septum Seal, Platinum cured silicone WHEATON® µL MicroLiter® Concentrator, Caps & Septa

Butyl rubber/PTFE septa are used with ketones and acids, and where silicone-containing septa do not perform well. Both types of silicone and butyl rubber septa have a PTFE barrier layer which faces the sample, which reduces the contact between the sample and the silicone and butyl rubber.

Three Layer Septa is made of preconditioned silicone rubber and is 3.81 mm (0.150 in.) thick. The average life of these septa is up to 100 injections with a 26s gauge needle. The maximum operating temperature is 200° C. Preconditioned silicone rubber septa, 3.81 mm (0.15“) thick . Compare this item.

PTFE/Red Rubber Septa offer good solvent resistance, good resealing characteristics and resistant to coring. They are an economical choice where a PTFE barrier is desired. The recommended operating temperature range for this septum is –40 to 100°C PTFE White Silicone PurePakTM Septa: (C4020-32) PurePak PTFE/Silicone septa are an excellent
