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.

PhotoNMR Sampling Device, complete, for air/moisture sensitive samples.
Consists of one each: NE-CAV5-G-140, NE-CAV-P, NE-379-5-COA and NE-379-5-COIC. 

For samples that are not air/moisture sensitive, you can use our
Coaxial Inner Cell, NE-5-CIC, to hold the optical cable and a precision
5mm NMR sample tube, NE-HP5-7 for the sample. Both items can be
found on our website at their respective links. 



Coaxial Inner Cell for PhotoNMR Sampleing Device, NE-379-5-Br.
Accepts a 2.2mm OD optical cable with a 1mm diameter optical fiber with 5.5cm exposed length.
Supplied with an end cap to accomodate the 2.2mm diameter cable and protect the edge of the inner cell.
A cap to secure the cell in the outer tube is also supplied.



NE-379-5-Br-A, PhotoNMR Device for non-air/moisture sensitive NMR samples.
Consists of a special coaxial inner cell, NE-379-5-COIC-Sp-A, which accomodates
an optical cable with a sheath diameter of 2.2mm and a 1mm diameter fiber 
exposed for a length of 5.5cm. The inner cell is supplied with an end cap to protect
the edge of the glass a retaining cap to hold it securely in the outer tube. 
A precision 5mm OD NMR Sample Tube, NE-HP5-7, is included. 



Glass Body for the PhotoNMR Sampling Device



Optical Adapter, for use with the NE-CAV5-G-140.
For use with the Opitical Inner Cell, NE-379-5-COIC to secure it in the glass body.
