The thinner Septa thickness is more suitable for puncture. If the automatic injection needle is a large blunt needle, Aijiren recommends buying a pre-slit septa, but this type of septa is not suitable for repeated injections, otherwise it may fall into the Vial. Aijiren uses a glue-free bonding process and does not introduce adhesives. The septum retains the excellent resilience performance of Silicone, which is softer than the septum of the bonding process and can provide a better injection needle for the autosampler. Protection; Aijiren’s strict production management and dust-free production workshop ensure that the products are clean and can be used without cleaning.
