Crimp closure, N 20, alu.,pressure rel.,c. hole,Sil. blue tr./PTFE colorl.,3.0mm

Soft to penetrate, high purity Silicone/PTFE closure for sensitive analysis. Can be used at very high temperatures. The bridges of the cap's scorelines break open at an internal vial pressure exceeding 3 bars (± 0.5 bars), thus releasing overpressure in a crontrolled way. Functionality of the cap is not depending on the design of the vial's crimp neck (beveled top, flat crimp neck).

Additional cap features Pressure release cap (safety) - bridges of the scorelines open at a pressure of more than 3 bars (± 0.5 bars) and release pressure in a controlled way
Additional closure features Temp. resistance -60 °C up to 200 °C / analytical purity - high / easy to penetrate / medium resealability
