NorLoc™ 5 mm Cap Assorted - 100 Pack
Details
Our 5mm NorLoc® NMR tube cap is an advanced closure specifically designed for 5mm NMR tubes that renders the traditional 5mm NMR tube cap obsolete.
It is available in a vibrant array of brilliant colors and performs flawlessly in the broadest range of applications, from small numbers of manually prepared and analyzed NMR samples, to the fully automated, high-throughput capabilities of the Bruker SampleJet system being employed more widely than ever in today’s laboratories.
The patented design of our 5mm NorLoc® NMR tube cap remarkably outperforms the only available alternative, the traditional 5mm NMR tube cap, as shown by the following evaporation test data:
