The 24mm Silicone/PTFE Septa produced by Aijiren uses high-quality PTFE and Silicone as raw materials. Silicone protects the puncture of the injection needle and can meet multiple punctures of the automatic injection needle. The 24mm Silicone/PTFE Septa has high chemical resistance, acid and alkali corrosion resistance, In addition, the contact between PTFE and reagents is resistant to high temperatures. The thickness of 3mm ensures that the 24mm Silicone/PTFE Septa has a strong repetitive seal, and it can still maintain good airtight performance after multiple injections. Polytetrafluoroethylene is a material with better chemical conditions at present, and can withstand strong acids and alkalis. After the two materials are combined, Septa's Vial can be used for various laboratory purposes, such as sealed sampling, chemical storage, etc. It is worth noting that the thinner thickness of Septa is more suitable for puncture. If the automatic injection needle is a large blunt needle, a Pre-slit septa is required, but the pre-slit septa is not suitable for repeated injections, otherwise it may fall into the Vial.
