Oct 21, 2022 · Oct. 21st, 2022. The septa and vial caps are essential parts of HPLC vials. The vial cap serves as a barrier, keeping outside contaminants out of the vial and preserving the integrity of the sample. The septa, a seal between the injection needle and the vial composed of silicone, PTFE, or rubber, ensure accurate and exact sample injection.

When selecting a vial, cap and septum to contain analytical solutions, there are several factors to take into account. In most analyses, the cleanliness of the vial and the septum are most important. 1,2 With analyses where multiple injections of the same analyte (s) are performed over time, the ability of the septum to reseal is a consideration.

Products. Septa. By definition, a rubber septum consists of a disk of rubber or similar material used to seal a vial or other device. It is installed along the inside of a cap, which is typically made of metal or plastic. A syringe needle pierces the rubber septum for the purpose of injection and, on withdrawal, the elasticity of the septum

vial septa contain small quantities of organic materials that might be detectable with the analytical instrumentation being used. For most GC/MS and other high-sensitivity detectors, Phenomenex recommends septa materials with the Cert+ designation; these are the cleanest and highest-performing products in the Verex line.

This magnetic screw cap has been developed for the CTC instrument. The vial has a precision thread with numberous threads to force the septa against the vial to seal it to be gas tight. The center hole is designed to be used for SPME as well as standard Headspace analysis, but still offers enough. Compare this item.

Jul 1, 2016 · While gas chromatographers may take their septa for granted, in fact these small and seemingly unremarkable polymer discs keep air out of the carrier gas stream when used in an inlet and keep sample intact and uncontaminated when used in a sample vial. Choosing the wrong septa can compromise method accuracy and repeatability as well as reduce column lifetime in extreme cases. This installment

Features and benefits. Trajan septa undergo conditioning (thermal and chemical) to reduce siloxane bleed. Siloxane bleed can occur during heating, solvent interaction or piercing by the autosampler needle causing the material to become stressed. Septa liners are often laminated with a layer of high chemical resistance material such as PTFE or FEP.
