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

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.

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

General Purpose Septa Economy Blue Silicone Soft - easy to penetrate Maximum temperature of 250°C Designed for non-demanding, routine applications. Durometer rating of 40 - 45. Suitable for 90% of all GC analyses. Compare this item 8-425 Septa National Scientific Compare this item Septa Guards EP Scientific Products

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. Types of silicone rubber septa PTFE/silicone – ST1, ST15, ST18, ST2

Septa are selected based on the chemical properties of the sample and the temperature to which the vial will be subjected during the analysis. PTFE/Silicone septa are for use with most organic solvents but chlorosilanes. It has good reseal ability and can withstand a temperature of 250°C.

Mar 22, 2020 · Due to the relatively thick and blunt HPLC needles, only Silicone / PTFE closures, either with or without slit, should be used in combination with them. Screw thread closures N9 (9mm) 2ml vials and closures are universally suitable on most autosamplers, convenient in handling and available in a broad selection of different cap colors and septum

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. Compare this item Aluminum Seals with PTFE-Faced Silicone Septa DWK Life Sciences (Kimble)

PTFE/Silicone septa are formulated for different hardness (durometer) meeting requirements of various needle types. Formulations offering highly consistent performance, lowest background/blank value, and good chemical compatibility, effective sealing/resealing and low penetration force make PTFE/silicone septa suitable for all types of
