网页Don’t let your septum be the cause of injection failure. The septum you choose for your autosampler vial can impact sample evaporation, sample security, needle bending and blockages, and instrument down time. Don’t let the complexities of septa selection slow you down. Use the simple online Aijiren Tech Septa Selection Tool.

网页Aijiren produces matching Closures for HPLC Vials, especially Septa, which is made of Silicone and PTFE. Septa can ensure that the hplc vials are sealed. At the same time, it must ensure that the automatic injection needle can penetrate into the interior of Vias for sampling, so for Septa There are certain requirements for the thickness.
