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. Amberized NMR tubes ship with economy caps.

Standard Series™ Ultra-Precision NMR Tubes, 5 Pack - 5mm
- 500MHz
- 7 Inch (178mm)
- 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. |

4mm, Standard, Natural Quartz EPR Sample Tubes, 5 Pack Norell EPR tubes produce lower background signals and have better resistance to breakage than competitor brands. Our proprietary technical treatment reduces background noise along with the benefit of protecting against tube breakage. Additionally, we have designed a new fluoropolymer closure system around our fire-polished tube ends that prevents sample loss during temperature gradients. Available in both standard and ultra precision. Supplied with tapered fluoropolymer caps. - 4mm
