Application Notes

Cylindrical microcells can be customized in lengths to match your probe Note: Positioning rod should be removed prior to recording the spectrum. Technical Tip: To improve the shimming quality and signal lock, surround the microcell with reference solvent to reduce the susceptibility differences between the inner and outer compartments of the assembly. Resonance Report: For detailed explanations of the application of Coaxial Inserts and Microsampling see Resonance Report NMR-007 and NMR-008

5 mm Screw-Cap NMR Tubes

Commonly used in sample degasification these tubes can maintain vacuum quality of >10-4 torr. For better vacuum, please check our Pressure/Vacuum Tube and Quick Pressure Valve Tube .Tube comes complete with open top screw cap and septum. Caps and septa can be ordered separately; see table.Note: Items marked CALL may have limited availability.

Application Notes

PTFE/Rubber - Laminated discs with a sheath of PTFE bonded chemically to pharmaceutical rubber. Inert to most solvents and many corrosives. Not recommended for multiple punctures.PTFE/Silicone - Laminated discs with a sheath of PTFE bonded chemically to silicone. Inert to most organic solvents and compounds; however, not recommmended for use with strongly corrosive materials. Remains reliable after multiple punctures.
