PTFE/natural red 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. Natural rubber septa are offered assembled into aluminum crimp seals. PTFE/synthetic red rubber septa: (PTFE/RR)

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

These HPLC and GC vials are available as snap, screw or crimp in style, 15uL to 20 mL in sample size, and various of low bleed and high-quality material composition. For GC, GC/MS applications where sample matrices contain volatile or semi-volatile analytes of interest, the most common choice are crimp style vials to limit sample contents from leaking from the vial/closure combination.

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 time
