Opening and closing the door
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.
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.
