JEOL Single Tilt Beryllium Retainer (EM-21150)

Under Construction!

Here are some additional images of the JEOL single tilt beryllium holder. Remember that this is a grid retainer, meaning that the entire grid-holding apparatus can be removed from the specimen rod.

You can simply loosen the screws and dump both them and the plate into a Petri dish lined with filter paper. Make certain that none of the small pieces get lost!

This is considered bad practice since it is more likely to generate toxic beryllium dust as the plate grids against various things. Note the cresent-shaped Be washer sitting on the Be plate. This is not stored inside the holder, but rather in a separate container where the entire retainer is stored.

Rock the tool towards the end of the holder (the part that stays outside the column) and then lift the retainer up and off of the pin that holds it in place using a pair of heavy duty forceps.
