The NORELL® NorLoc™ Generation II Security Cap™

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

    The standard 5 mm and 3 mm 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.

    The patented design of our 5 mm NorLoc® NMR tube cap remarkably outperforms the only available alternative, the traditional 5 mm NMR tube cap, as shown by the following evaporation test data:
