Tip-Off NMR Sample Tube, Specialty NMR Sample Tubes
500-700 MHz
Sample tube NE-UL5-7
5mm OD x 0.38mm wall x 7” long
Type 1, Class B borosilicate glass


Both Pyrex and non-Pyrex tubes are offered.  Pyrex tubes are necessary if you need to reopen the tube and do additional glassblowing.  The non-Pyrex tubes are ideal for samples that will be archived.  In both cases, a 50mm section of 5mm OD tubing is sealed to a 7” sample tube.  The extra tubing allows the tube to be secured in the Tip-Off Adapter with ample length for safe flame sealing.  A uniform constriction, with a 2mm ID, is placed just above the 7” length.
