compatibility, effective sealing/resealing and low penetration force 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

PTFE/silicone – ST101, ST14. A very pure soft silicone laminated to PTFE. Septum resists coring and is recommended for instruments with fine gauge needles. Also recommended for LC-MS and GC-MS due to high purity.

High leak tightness is achieved through the use of our PTFE coated silicone seal.Septa are available in a variety of materials and thicknesses. PTFE Natural Rubber are moderately priced seals for GC and HPLC with good chemical properties. They are ideal for multiple injections due to high resealability, but not as easy to penetrate as PTFE/RR. PTFE/High Performance Rubber is a highly pure

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to provide for easier needle penetration as well as to release the vacuum that forms when a large volume of sample is withdrawn from a vial.

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. Compare this item.

Rubber septa. Used primarily for routine analysis in gas chromatography. Offers moderate ability to reseal and good chemical inertness. Not recommended for multiple injections or holding samples for further analysis. PTFE is protective layer that once broken exposes rubber to chemical attack. Types of rubber septa.

J.G. Finneran. The Finneran 24 mm septa is mainly used with screw thread closures for tight sealing of the stored sample. It is mainly used in research laboratories or in chemical industries. This septa is made of sturdy PTFE/silicone material which ensures long lasting usage and durability. Compare this item.

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.
