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:
