Questions

  1. Are these caps gas-tight? Can be used with any kind of 4 mL vials or they are meant to be used with specific vials?

    1 answer
    1. No, this product is an assembled screw-hole cap with a PTFE/silicone septum. There is no indication it is gas-tight. It can be used with any vials with 13-425 threading.

      For gas-tight applications, the magnetic screw cap for the CTC instrument, such as SU860101, is currently offered. This cap features precision threading with numerous threads to force the septa against the vial making it gas-tight.
