Vial inserts are used to reduce the capacity of the vial to accommodate smaller samples. Typically 150 to 400µL in volume, they may be made of glass, plastic, or a combination of materials. Closure options include those with and without septa, snap caps, screw caps, and crimp top caps. Vial caps and septa help prevent leakage and sample loss
The vials also have high temperature resistance and are suitable for use in temperatures between -50°C to 120°C (although a rapid change in temperature of the products should be avoided). The Performance Level 1 vials are designed to identify those which are suitable for simple routine, testing with limited budget.

Pre-slit PTFE/Red Rubber Septa: A PTFE/Red Rubber septum is provided with a thin 0.003” PTFE layer laminated to our standard red rubber 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to provide for easier needle penetration as well as to release the vacuum that forms when a large volume of sample is withdrawn from a vial. This septum provides chromatographic
PTFE/Natural Red Rubber 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.
