Mar 31, 2022 · 3. Silicone/PTFE – If you have a thin needle, and you need to use a thin septa. Silicone/PTFE, slit – If you have a thick needle, and you need to use Slit/pre-cut liner as penetration aid (HPLC) Silicone/PTFE septa – If you have a critical analysis that needs a clean liner.

Different septa material for LC and GC applications There are many different types of materials used to produce the septa found in LC and GC vial caps. This document will provide you with the technical guidance you need in order to make the right selection. Choosing the right septa When selecting which septa is right for your experiments, it

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.

The slit allows ambient gas to equalize the gas in the vial so that a vacuum is not created in the vial from the tight seal around the needle. If coring or clogging from a narrow needle or needle deflection from highly durable septa material is a concern, then choosing a pre-slit septum is a better choice.

Oct 20, 2021 · Aijiren cap septa offers new septum materials and unique processes to improve septum sealing integrity and reduce the risk of sample contamination. Septa are 0.035” Natural Silicone with 0.005” Natural PTFE. High quality silicone is used to ensure proper re-sealing and reduced coring. Designed for multiple injections and/or longer sample

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.
