Opening and closing the door
Test procedure:
An Automatic-Desiccator with three shelves is loaded with six bottles of 1.5 litres capacity on the two lower shelves. In addition, there are 12 beakers on the upper shelf. A relative humidity of 13% is produced in the desiccator. The airtight door is opened for 10 seconds and closed. The curves show the relative humidity versus time.
Results:
The humidity falls to the initial value of 13 % after a short period of time. Application errors that may occur with silica gel are avoided.
