• A patented Security Band™ that engages and locks into the NorLoc II Security Cap™, securely joining the cap to the NMR tube.
• The edge of the Security Band™ also denotes a stop position for partial, temporary cap placement, allowing quick and easy access to the NMR tube.
• A patented proprietary surface treatment with a unique textured surface ensures precise and positive retention in Bruker, Agilent/Varian, and Jeol spinner turbines.
• A patented marking or label area that also functions as a clear visual indicator, indicating the limit for full and complete closure with the NorLoc II Security Cap™.
• The Secure Series NMR tubes are available in two types: the Secure 33 Series and the Secure 55 Series in both 178mm and 203mm lengths.
• The Secure 33 Series NMR tubes are made from ASTM Type I Class A borosilicate glass (Pyrex® 7740 or equivalent) and have comparable glass properties to the Norell® Select Series NMR tubes.
• The Secure 55 Series NMR tubes are made from ASTM Type I Class B borosilicate glass (N-51A or equivalent) and have comparable glass properties to the Norell® Standard Series NMR tubes.
• The Secure Series NMR tubes remain completely compatible with standard, classic NMR tube caps in both 5mm and 3mm sizes.
STAGE I
For all Bruker/Agilent-Varian/Jeol spinner turbine based NMR Spectrometers
Our dual purpose proprietary security band allows safe, reliable and secure placement of the NorLoc II cap. Simply align the specially enlarged cap opening with the NMR tube and lightly push the cap to the natural stop created by the security band. The ensuing placement and single stage seal is a novel progression in lab safety with enhanced performance and ergonomic feel.
STAGE II
For Bruker Sample Jet Systems
For Bruker Sample Jet use, apply additional pressure on the NorLoc II cap to engage the cap's locking mechanism onto the tube's security band. You will know the cap is properly engaged when the bottom of the cap touches our exterior tube marking area. Our dual stage mechanism provides superior hermetic sealing and the interlock forms a positive physical restraint system preventing tube and cap separation especially with troublesome NMR solvents such as chloroform-d.
