The IPV Valved NMR Sample Tubes for Intermediate Pressure are very useful for experiments requiring conditions such as pressurized inert atmosphere blanketing, addition of reactive gaseous reagents under pressure, containment of low boiling point solvents or samples at elevated temperatures, etc.
The IPV Valved NMR tube quickly and easily connects to 1/16 inch (1.6mm) OD PEEK or PTFE pressure tubing (a common size of laboratory instrumentation pressure line often found on HPLC and GC instruments) using the included 1/16 inch flat-bottom port ferrule and #10-32 threaded compression nut.
We recommend limiting the maximum operating pressure to 600 kPa (6 bar, 87 psi) for a 5mm thin wall NMR tube, 900 kPa (9 bar, 130 psi) for a 5mm medium wall NMR tube, or 1200 kPa (12 bar, 175 psi) for a 5mm heavy wall NMR tube.
Though the IPV Valved NMR Tube can be used under full vacuum, the small inner diameter of the 1/16 inch tubing used may cause a longer evacuation time to reach a high vacuum level.
