What is a HPLC Vial Septa? 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 makes Septa not easy to deform.
In addition to sealing, Septa also has an important function. When HPLC Vials are used in an autosampler, the injection needle needs to be inserted into the HPLC Vial to draw samples. Opening the Cap will cause sample contamination. Therefore, Aijiren provides Caps with Center Hole, and the automatic injection needle needs to pierce Septa into the HPLC Vial to draw samples.
Aijiren's HPLC Vial Septa is processed through Aijiren's exclusive process to ensure that Septa is not easy to deform or fall off, and it is not easy to produce debris when the sampling needle of the autosampler is punctured, and it is not easy to fall off and fall into the sample to contaminate the sample.
Generally speaking, Aijiren's HPLC Vial Septa has the Silicone side facing up and the PTFE side facing the sample. Because PTFE is not easy to react with chemicals, it can ensure that the sample is pure and not contaminated. Aijiren's HPLC Vial Septa and Caps are installed and fixed, which is convenient for customers to use.
HPLC Vial Septa produced by Aijiren is usually white, red, and blue. Silicone and PTFE use different colors to distinguish the front and back. In addition to HPLC Vials, Aijiren also produces Septa from Headspce Vials, Septa from Sample Storage Vial, and Septa from COD Test Tube. This is the end of the introduction to HPLC Vial Septa. I hope that after reading this article, you can understand what HPLC Vial Septa is used for. Welcome to purchase Septa from Aijiren.
