Silicone septum for chemical research

Description. Thermo Scientific™ Septa for 8-425 Screw Thread Caps are constructed of PTFE, PTFE/rubber, or PTFE/silicone to suit a variety of HPLC, GC and IC applications. Choose from Thermo Scientific™, Thermo Scientific™ National™, and Thermo Scientific™ Chromacol™ brands. PTFE Disk septa are chemically inert.

PTFE/Silicone septa are ideal for use in most HPLC and GC applications where resealability and purity are critical. Pre-slit PTFE/Silicone Septa Pre-slit septa are offered in many of the same formulations as for non-slit PTFE/silicone septa and shares most of the physical and chemical characteristics. The septum is provided with a

After piercing with a non-coring needle, rubber closes the puncture, protecting the contents of vessel or container from atmosphere. We also provide Suba-seal silicone rubber septa for high heat applications (up to 200 °C continuous) with improved chemical resistance compared to natural rubber and autoclavable for sterile uses.

Silicone rubber septa. High quality, silicone rubber laminated to PTFE. Use when excellent resealing qualities are a must. Septum resists coring and is recommended when multiple injections are required. Preferred septa for use in liquid chromatography applications.

The silicone is faced with highly resistant PTFE to protect the silicone from chemical attack by the solvents. The septum is suitable for use with all GL 45 sizes of the DURAN® GL 45 bottles from 100 to 20,000 ml. A liquid tight seal is provided when used in combination with the red PBT GL 45 open topped screw cap. Wide temperature usage range

PTFE/Silicone Septa: (T/S) High quality, pure silicone is laminated to 0.005” thick PTFE to give a pure, highly inert septum with excellent resealing characteristics even after repeated punctures. PTFE/Silicone septa are the preferred product for use in most HPLC and GC applications where resealability and high purity are critical.

Apparently the silicone septum doesn't withstand organic solvents very well, so better prepare a new blank for each sequence. The attached image shows the old blank (black) compared to a fresh one

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. Related Products: Screw Cap With Septum. Compare this item.

With a recommended operating temperature range of -40°C to 200°C, the PTFE/Silicone septum is chemically resistant until pierced, then achieves the chemical compatibility of the silicone after being punctured, making it a great choice of apparatus for a wide range of applications.

include PTFE, silicone, natural red rubber, butyl rubber, Viton, polypropylene and polyethylene. PTFE is often laminated onto the sample facing side of a resealable septum to improve solvent exposure characteristics. Laminated septa will generally exhibit greater chemical resistance until the PTFE layer is punctured.
