Tube Safe Valved NMR Tube Carrier

The Tube Safe Valved NMR Tube Carrier was originally developed for our own Valved NMR Tube shipping needs. We've been shipping our Valved NMR Tubes in this design since 2022. After receiving client requests for the Tube Safe for their own internal storage, transport and shipping needs we decided to offer it as a stand-alone product.

NorLoc™ Generation II Security Caps

Advance to the next level of sample security, personal safety and time savings. Combine Norell® NorLoc™ II Security Caps™ with Norell® Secure Series™ NMR tubes and experience the ultimate sample containment system.

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.

The NorLoc™ II Security Caps™ feature an internal patent pending design improvement that not only addresses many of the flaws in the traditional NMR tube caps, but the superior design of the NorLoc™ II Security Cap introduces many substantial improvements not found in any other NMR tube caps.

Amberized NMR Sample Tubes

Amberized NMR tubes offer photosensitive materials protection from visible and ultraviolet radiation. Typical optical transmittance values at 650nm to 300nm range from 0% to 50% (this region includes the visible spectrum). From 300nm to 190nm, in the UV region, the optical transmittance is virtually 0%, due primarily to the intrinsic opacity of glass to UV radiation.

Standard Series™ for Routine NMR

Our Standard Series NMR tubes are manufactured out of ASTM Type 1 Class B glass, commonly referred to as N-51A. Applications that are suited for using this type of glass are routine NMR where samples are run under room temperature with no thermal gradients. It is therefore not recommended to fuse this glass with standard vacuum manifolds and the like, since these are generally made out of Type 1 Class A glass. Each NMR tube is checked for concentricity and camber specifications utilizing the latest computer technology. At Norell® we have taken NMR tube manufacturing to a new level of science.

Through our advanced manufacturing process, the NMR tube bottoms are uniformly hemispherical and consistent, thereby minimizing shimming and susceptibility differences among samples. This uniformity extends throughout the wall thickness of the tubes, maximizing the concentricity among tubes and lots. This translates to more consistent placement of the contained sample volumes in today’s advanced, highly homogeneous, high field NMR magnets. NMR tubes are manufactured with round bottoms and are available with flat bottoms upon request. We manufacture all NMR tubes in any length upon request.
