Septa materials comparison in HPLC

Some solvents that are commonly used for HPLC, UHPLC and GC experiments can impact the septa integrity. Temperature If you need to place a capped sample vial in a high temperature environment, then you will need to consider septa materials that are able to withstand high temperatures.

Jul 23, 2020 · By definition, According to the definition, Septa is a circular gasket made of Silicone or silica gel. In HPLC analysis, Septa is usually placed in the Cap of the HPLC Vial to seal the HPLC Vial to ensure that there is no gap between the Cap and the Vial.Aijiren's Septa uses a double-sided material, and the combination of PTFE and Silicone

Septa. 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 synthetic red rubber septum

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.

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.

PTFE/Silicone septa are ideal for use in most HPLC and GC applications where resealability and purity are critical. Pre-slit PTFE/Silicone Septa Pre-slit septa are offered in many of the same formulations as for non-slit PTFE/silicone septa and shares most of the physical and chemical characteristics.
