This production method guarantees the quality of the septa, not easy to deform, not easy to break, not easy to fall off, and resistant to high temperatures. To ensure the accuracy of the experiment and ensure the sealing, it is the partner of 9mm screw closures, which is very suitable for the use of 9mm hplc vial in chromatography.

Septa uses a composite of Silicone and PTFE. This composite process is Aijiren’s exclusive process and does not use adhesives for composite. This composite process ensures the flexibility and puncture of Septa. Since the Septa thickness of the 20mm Crimp Top Aluminum Closures is 3mm, it can meet the sealing requirement and bring a lot of trouble to the puncture of the automatic injection needle. The importance of composite craftsmanship is particularly prominent, which allows Aijiren’s unique craftsmanship to give customers a different experience.
