Standard Series™ High-Precision NMR Tubes, 5 Pack

• 400MHz 
• 8 Inch (203mm)
• 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 temperatures 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.

Amberized Standard Series NMR Sample Tubes, 1 Pack

• 5mm
• 7" (178mm)
• 500MHz
• For Routine NMR

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.

Available with ULTRA-THIN wall NMR Tubes.

Pictured with optional NorLoc™ Cap. Constricted NMR tubes ship with economy caps.
