11mm Snap Neck Closures
The Snap Cap is made of polypropylene, and the raised part of the Cap is very convenient to be stuck in the groove of Vias to ensure fixation. Septa is made of Silicone and PTFE adhesive-free composite. It is soft and easy to puncture. It is very suitable for automatic sampling. The side of PTFE in Septa faces the inside of Vias, sealing without affecting the sample.
