Gas Cylinders
(Not Supplied Accessory)
To control the gas concentration, gas cylinder(s) or a laboratory gas handling
system with pressure reduction valves are required.
Gases: Carbon Dioxide (CO
2
) to regulate CO
2
concentration; Nitrogen (N
2
) for the
reduction of O
2
concentration. (e.g. 50 Liter cylinder).
Pressure Reduction Valve for Carbon Dioxide and Nitrogen Gas Cylinder
The pressure reduction valve must have two gauges – one for the pressure in the
bottle and one for the reduced pressure of max 2 bar (max 29 psi).
Take care that the display for regulating the pressure has a range of 5 bar
(72.5 psi) or maximum 15 bar (217.5 psi) to allow regulation from 1 – 2 bar).
Make sure that the pressure reduction valve is designed for use with biological
applications (ask manufacturer).
The connection from gas cylinder to pressure reduction valve is different for each
country.
Check with a gas bottle company in your country for the proper
connection!
Check that the connection piece of pressure reduction valve matches the inner
diameter of the gas tube to the instrument (The inner diameter of this tube is
approx. 6mm). The tube on the connector to the pressure reduction valve must
be secured with a plastic clip; a pair of pliers will be necessary to perform this
task.
Make sure that there are no bends or kinks in the tubing.
If necessary, convert bar into psi: bar x 14.5 = psi (pounds per square inch), e.g.
2 bar = 29.0 psi.
To protect the gas cylinder from falling, a cylinder stand or table mount (with a
securing chain or strap), or gas cylinder cradle can be bought from a gas cylinder
company or ordered from a laboratory catalog.
