Tapered Fluoropolymer Caps for Bruker MATCH™ Tubes

• 5.0mm
• PTFE Tube Cap
• Packed in Lots of 5
• Black

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.

5mm Valved NMR Tubes for Intermediate Pressure, 1 Pack

• 5mm
• 500MHz
• 7" (178mm)
• Thin Wall

This valve incorporates an advanced seal design that is superior to alternative valves currently available from other manufacturers. A fluoroelastomer o-ring imparts resilience and a high degree of chemical resistance. A PTFE sheath, forming the primary seal, completely covers the fluoroelastomer o-ring, creating the ultimate barrier against aggressive, reactive substances while providing a totally inert surface.

These pressure tubes facilitate experiments requiring conditions such as pressurized inert atmosphere blanketing, addition of reactive gaseous reagents under pressure, containment of low boiling point solvents or samples at elevated temperatures, and so on.

We recommend that the maximum operating pressure should be limited to 600 kPa (6 bar, 87 psi) when using a thin wall pressure tube, up to 1200 kPa (12 bar, 175 psi) if using a heavy wall pressure tube. (Please see accompanying table for complete details).

The NORELL® NorLoc™ Generation II Security Cap™

• 5mm
• Sea Glass
• 100 Pack
• Patented Design Elements Allow Safe & Secure Closure

The standard 5mm and 3mm NMR tube cap designs have existed for decades. Many users can attest to  the significant flaws inherent in the traditional NMR tube caps, especially when faced with the chore of capping numerous sample tubes.  

NorLoc™ Caps work well with any NMR tube but are best when paired with Secure Series™ NMR sample tubes from Norell®. Internal components of NorLoc™ caps engage with the security band printed on our Secure Series™ NMR tubes and indicate one of two stages of closure. 

Select Series™ 5mm, Ultra-Precision NMR Tubes, 5 Pack

• 5mm
• 900MHz 
• 7 Inch (178mm)
• Ships with Economy Cap. NorLoc™ Caps Sold Separately.

Our “Select Series™” NMR tubes are manufactured out of ASTM Type 1 Class A glass, commonly referred to as Pyrex® 7740 (Corning), Duran® (Schott Glass), or Kimax® KG-33 (Kimble) glass. 

Key properties that make this glass type desirable for NMR are its high degree of thermal shock resistance and low expansion coefficient. This allows for a greater margin of safety from breakage when used in variable temperature applications and freeze/thaw cycling, or under any other application where large temperature variations are required in the experiment. 

Each NMR tube is checked for concentricity and camber specifications utilizing the latest computer technology.
