Gas Chromatography since 1965
UHP Two Stage Bar Stock Regulators
The AGC brass bar stock regulators are designed to regulate ultra high purity
non-corrosive gases commonly used in our gas chromatograph applications requiring
both high reliability and diffusion resistance. The metal to metal diaphragm to body
seal design assures maximum diffusion resistance. Convoluted stainless steel
diaphragms provide enhanced performance and excellent accuracy. The two-stage
design provides constant pressure control regardless of changes in cylinder (inlet)
pressure.

Standard Features
• Metal to Metal Diaphragm to Body
Seal (without back-up o-ring) assures
maximum diffusion resistance.
• High Purity Regulator Design permits
vacuum purging of regulator.
• Diaphragm Seal Outlet Valve maintains
gas purity.
• Filter traps foreign matter, extends
regulator life and reduces maintenance.
• 1/16" NPT Female Bonnet Vent Ports
allow bonnets to be connected to a
vent line or disposal system as a
precaution in the unlikely event of a
diaphragm failure.
Optional Features
• Mounting Ring permits regulator to
be panel mounted.
• Quick Mount Assembly provides for
convenient and safe wall-mounted
installation.
• Internal (Inboard) Helium Leak Test and
Test Report determines inboard leak
rate of gas from regulator to atmosphere;
test report certifies leak rate of
less than 2 x 10-8 sees air equivalent.
• External (Outboard) Helium Leak Test
and Test Report determines outboard
leak rate of gas from regulator to
atmosphere; test report certifies leak
rate of less than 5 x 10-7 sees air
equivalent.
