Opening and closing the door
Test procedure:
A desiccator with three shelves is loaded with approx. 30 beakers. A relative humidity of max. 7% is maintained inside the desiccator. On one shelf and at the bottom of the desiccator there is one tray (350 x 240 mm) with 500 g of silica gel. Then the airtight door is opened for 10 seconds and then closed. The curves show the development of humidity.
