How do I prepare my pH electrode for long-term storage or shipping?

To safely store or ship your MANTECH pH electrode, first fill the electrode with fill solution and fill the storage boot ¾ full with fill solution. Then, insert the probe into the boot and screw tight. Place the fill solution plug in its hole and parafilm over the plug, as well as around the body. Then, parafilm over the cable connection spot, making sure not to overlap with the parafilm around the plug.
