Opening and closing the transfer chamber

Test procedure:

Due to the constant gassing with nitrogen the relative humidity inside a glove box with transfer chamber is 15 %. A SICCO Gas Dosing Controller is connected during the lead in of nitrogen in order to control the gas supply. A SICCO Gas-saving Valve is connected to the outlet for aeration. In the Gas Dosing Controller, the attainable required humidity is adjusted to 10 %, the flow rate to 8 Liters / minute and the pressure reducer on the nitrogen bottle to 0,5 bar. The transfer chamber is not purged with gas. The relative humidity inside the transfer chamber is 47 % at the beginning of the test procedure. The door of the transfer chamber in direction of the workspace is opened completely for 30 seconds. The curves show the relative humidity versus time.

Results:

Due to the opened door of the transfer chamber in direction of the workspace the relative humidity inside increases slightly to approx. 20 %. After approx. 10 minutes the initial value is reached again by re-supply of gas.
