Bruker tapered PTFE caps

Bruker Match^™ tube caps are specially machined from PTFE fluoropolymer, are color coded by tube size, and correspond to the color of the tube clamp in the Match^™ Insert Assembly, This enables quick identification of matching components. The tube cap incorporates a slightly tapered inner diameter. Initially, the cap aligns and pushes easily onto the tube, it then becomes progressively tighter as the tube reaches full depth within the cap, creating a positive seal to preserve volatile sample solutions throughout short or long term storage.
