  The Bruker MATCH™ tube caps, 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, allowing quick identification of matching components.
  
  The MATCH™ 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.
