WARNING To avoid a burn hazard, use an insulated cloth or hot pad to handle the heated
desiccant canisters. Always wait until the canisters have cooled to room temperature
before installing them in the instrument.
2. Use an insulated cloth or hot pad to remove the desiccant canisters from the oven.
Immediately place the hot canisters in a dry environment such as a desiccator and allow
them to cool to room temperature. As soon as the canisters reach room temperature, you
must either install them in the instrument or seal them in an airtight container or bag.
Otherwise, they will absorb moisture from the air in the room and quickly become
saturated again.
