Select Series NMR tubes are made from Type 1 Class A glass of ASTM E438.
The Standard Series™ NMR tubes are manufactured out of ASTM Type 1 Class B borosilicate glass, and are designed to be used under ambient temperatures for chemical reaction monitoring, high through-put NMR and for general student use, where cost savings are important.
P(max) = (tube wall thickness in mm/tube O.D. in mm) X 2,000 psi
Example : 0.38mm/5mm X 2000 psi ≈ 150 psi
Select from the following quartz NMR tubes:
S-5-600-QTZ-7 for 600 MHz 7” long
S-5-600-QTZ-8 for 600 MHz 8” long
S-5-500-QTZ-7 for 500 MHz 7” long
S-5-500-QTZ-8 for 500 MHz 8” long
For a 5mm OD tube, the volume is 3.1416 X (0.42 cm/2)2 X 5.0 cm. Ans. 0.69 ml (1ml = 1cm3)
Both of these types of NMR tubes are used for protecting samples from atmospheric gases. The Norell VT NMR tube offers greater sealing ability under vacuum and pressure applications. The screw cap tube should only be used to seal samples under ambient pressure and temperature conditions. We recommend either the following:
