Isotope Photon Tritium Cell

IMPORTANT NOTE: This product DOES NOT include tritium vial. Please refer to our Tritium Primer to learn more about tritium and where to purchase it. This borosilicate glass tritium cell module is an exact replacement for the module included in the TEC Isotope Photon tritium fob. If you were to ever damage or lose the original module, this is an easy do-it-yourself replacement to get you up and glowing again! The Isotope Photon was designed around the concept of using a replaceable tritium module. This is not necessarily due to the need for a such a feature, but it allow us to use this standard design element to integrate this module into other future product designs. In addition, it also provides a component that others can use in their own designs for integrating tritium into their products.  What you get: (1) Replacement Borosilicate Glass Tritium Cell Module which includes: (1) Borosilicate glass window (2) Aluminum end caps (2) End cap O-rings (2) Tritium O-rings Borosilicate G
