Secure Series - NMR Tubes from NORELL®

Secure Series NMR Tubes

With A Patented Security Band™ • Now Available in Ultra-Thin Wall • Ultra-Thin Custom Quote Button Below

NORELL® continues its dedication to innovation with our Secure Series™ line of 5mm and 3mm OD NMR tubes paired with the NORELL® NorLoc II Security Cap™.

The Secure Series™ NMR tubes feature several patented design elements that add a superior level of sample containment and isolation, safeguarding the integrity of precious or critical NMR samples and assuring secure retention of the NMR tube in the spinner turbine.

• 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.

Secure 33 Series™ NMR Tubes

The Secure 33 Series™ NMR tubes are made from ASTM Type I Class A borosilicate glass ("low expansion" borosilicate glass such as Corning Pyrex^® 7740 or equivalent) and match the properties of the Select Series™ NMR tubes from Norell®. Because of the low coefficient of thermal expansion, Secure 33 Series™ NMR tubes show a high degree of thermal shock resistance, a necessary attribute to prevent breakage when large temperature variations are expected in variable temperature studies, degassing samples through freeze-pump-thaw cycles, etc.
