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.
The accompanying table includes caps for all current MATCH™ tube sizes, as well as for the 1.0mm OD size contained in older MATCH™ Tube Kits.
NMR tubes specifically made for the Bruker MATCH™ System feature eight different tube sizes to choose from.
