1. What are the power requirements for my glovebox system?

All standard glovebox systems are either 115V 15 amps for domestic installations or 220V 8 amps for international installations. A standard wall outlet should work fine for running the glovebox systems.

2. Do I need any other power for my system?

Your system comes with an electrical feedthrough to supply power inside the glovebox system. This is either 115V 10 amps or 220V 5 amps. A standard wall outlet will work fine for this as well. Please refer to Installation Requirements documentation for additional power requirements.

3. Do I need a ventilation/exhaust connection for my glovebox?

You will need to connect the common vent line to an exhaust connection in your lab. The common vent line connects all of the exhausts for the entire glovebox system into one connection at the top of the system. This is a 1.5” pipe connection labeled VENT at the top of the system, typically located behind the antechamber.

4. What kind of inert gases do I need to run my system?

You will need either nitrogen or argon at a purity of less than 10 ppm oxygen and moisture to operate the system. You will also need regeneration gas (3-5% hydrogen balance nitrogen or argon) for the regeneration process. A quality of 99.995% or better is required to operate the system correctly.

5. How much regeneration gas do I need and do I need to leave it connected all of the time?

You will need 1 standard cylinder of regeneration gas to start the system. One regeneration consumes half a tank of regeneration gas. You will most likely only regenerate your system once every 3-6 months and you can disconnect the regeneration gas when not in use.

6. Do I need a regulator to run my glovebox?

You will need a regulator to run your system. The regulator will need to deliver between 60 – 80 PSI of gas pressure at a flow rate of 200 l/min. The regulator will need to have a 3/8” hose barb connection and should be equipped with a shut off valve. Please see your installation requirements for details.

7. Do I need a regulator for the regeneration gas?

Yes. You will need a regulator for the regeneration gas. This regulator will need to deliver between 10-15 PSI of pressure and need to have a flow meter attached to deliver 15l/min of flow to the system while regenerating. This regulator will also need a 3/8” hose barb connection and should be equipped with a shut off valve. Please see your installation requirements for details.

8. Do I need to purge my system when I first set it up and how much purge gas do I need?

You will need to purge your glovebox when you first set it up. A standard single length system takes approximately 2 cylinders of inert gas to purge the system. As a rule, the amount of purge gas is easy to calculate. First you need to calculate the volume of your glovebox in cubic feet. A typical standard single length glovebox is approximately (4 ft X 2.5 ft X 3 ft) 30 cubic feet. An estimate is fine to use for this calculation. Then multiple the volume by 15 and you get a purge gas amount of 450 cubic ft. There is 300 cubic feet of gas in a standard gas cylinder so you will need 2 cylinders of gas. This is a very useful calculation for larger or smaller systems.

9. Does the glovebox need to be purged before I run a regeneration?

You must purge the glovebox prior to running a regeneration. The regeneration process uses the glovebox environment for cooling and therefor needs to have a low oxygen environment inside the glovebox.

10. Does the glovebox need water cooling?

No. The glovebox system does not require any cooling water to run.
