Glovebox
The Glovebox is located on the 7th floor of the Huygens in HL713a.
The manual can be found here: ilab_user_manual_final_6-7-13.pdf
The glovebox is capable of keeping O2 and H2O levels below 1ppm. O2 and H2O levels can be read out on the display on the top right. The system is equipped with a large and small antechamber, a gas purification system and vacuum pump to minimize concentrations of O2 and H2O inside.
The box is kept at a 5mbar N2 over pressure to prevent leakage from the outside into the box. (If the gloves are not pointing horizontally this indicates there is no proper over pressure inside).
General rules
Clean your items before bringing them in the glovebox.
Discuss your experiments with other glovebox users to avoid cross contamination.
Flush the antechamber 3 times when loading and unloading to prevent O2 and H2O contamination and unwanted chemical release respectively.
At all times it should be prevented that sharp objects are lying around, there's a high risk of piercing the gloves.
The gloves have a maximum reach inside, do not store stuff out of reach.
Clean up when done, bring in a new white solid waste trash can when full and remove old.
Using the antechambers
When possible use the small antechamber. Do not use the antechamber for storage.
Small antechamber
The antechamber can be opened from the inside or outside when it's on atmospheric pressure. The pressure can be read out on top of the antechamber.
Make sure antechamber is closed at the inside of the glovebox.
Turn black valve to “EVACUATE” to remove unwanted chemicals from the antechamber.
Turn black valve to “REFILL” antechamber will be filled with N2, fill to atm. pressure
Do this at least three times to minimize contamination.
Open antechamber and load, close antechamber.
Evacuate, Refill, do this at least three times.
Fill to atmospheric pressure, open antechamber from the inside.
Large antechamber
The principle for the large antechamber is the same as the small, but there is not one valve for the evac/refill but two separate valves.
Flushing
Regenaration
Changing gas cylinder
Working with high pressure gas cylinders should only be done by technicians!
Make sure full cylinder is ready to go.
Close gas cylinder
Open reducer
Open vent valve on top of the glovebox (large red handle) to empty the gas line
Check pressures on the reducer are zero
Close the reducer
Close vent valve
Unmount reducer from gas cylinder
Mount reducer to new gas cylinder
Make sure reducer is closed
Open gas cylinder with angle key
Open reducer and set pressure to 5 bar
Open vent valve completely to initiate automatic purge
Check 02 level
