CeBix™ & LaB₆ Cathode Storage Instructions

If storing cathodes for a short-term or long-term period, please remove the plug on the bottom of the black base on the inner shipping container. Remove the desiccant pouch. The remaining inner shipping container and acrylic cap are suitable for vacuum storage.

APTech recommends storing the inner shipping container in a clean and dry environment. The ideal place to store LaB₆ or CeBix™ cathodes is within a vaccum desiccator or in a nitrogen rich atmosphere. On-site APTech stores LaB₆ and CeBix™ in a vaccum desiccator as shown in the picture.

These are standard products that can be found at most laboratory supply stores. The main concern is the cathode being exposed to oxygen as this will cause the cathode to oxidze. Once oxidized, a thin white layer will form on various parts of the cathode and the cathode will no longer be usable.

APTech highly recommends that LaB₆ and CeBix™ cathodes be stored for no longer than 3-6 months. Please note that APTech will offer a warranty return analysis up to 6 months from the build date listed on the cathode datasheet and label.
