Helium Pressure Regulator Installation

Connecting the helium pressure regulator to a tank of pressurized helium.
Components needed:

• Pressure regulator for helium cylinder (with 0.45 micron in-line filter), provided with

unit (Figure 3.1).

• Cylinder of grade 4.5 to 5.0 helium (minimum 99.995% pure); maximum pressure of

2,600 psi, user supplied.

• 1 1/8" open-end wrench or a 10" or 12" adjustable wrench, user supplied.

Note: The regulator is intended for use only with helium gas under a maximum of 2,600 psi

of pressure. The outlet on pressurized helium cylinders used in the United States (maxi-

mum 2,600 psi) is compatible with the fitting supplied on the pressure regulator with the

PDS-1000/He unit (CGA 580, female fitting). Outside of the US, contact your local Bio-Rad

office for information regarding the proper cylinder/regulator fitting in your area.
