The general concept in using the device:
Prepare Oxygen sensitive samples in a closed system with the use of the valved NMR tube (glass body and plug included). In an Oxygen free glove box, remove the plug and replacement it with the Optical Adapter, NE-379-5-COA. Insert the Optical Inner cell, NE-379-5-COIC, and secure it with the nut and ferrule. You now have a closed system into which the optical fiber can be inserted. Some sheathing will have to be removed in order to fully insert the fiber into the cell. using the red cap on the Inner Cell will help secure the cable in the cell. Some tape may also be used.
