Norell™ 400MHz Borosilicate Glass NMR Sample Tube

Specifically designed for high-resolution NMR, tubes in the Select Series™ are manufactured from ASTM Type 1 Class A borosilicate glass and are compatible with Pyrex™, Kimax™ and Duran™. Whether spinning or non-spinning, doing structure determination of small molecules or determining the 3D structure of a membrane protein, the Norell™ Select Series™ of NMR tubes offers unsurpassed performance, reproducibility and reliability compared to other brands. You should see an immediate improvement in resolution when calculating i-coupling constants or acquiring data close to your spectrophotometer noise level, resulting in improved peak symmetry and shimmering times. In turn this leads to shorter analysis times and improved sample throughput. There are also no worries with freeze/thaw degassing or high temperature studies, these tubes can tolerate thermal shock up to 200°C. All tubes have polished ends making them less susceptible to breaking. Colored end caps are included.
