Backpressure Gas Regulator
Capillary GC inlet systems have backpressure regulators to
maintain a constant upstream pressure and rapidly respond to
catastrophic leaks. The 0–60 psig (0-414 kPa) operating range is
sufficient to operate a 105 m, 0.25 mm ID column at its opti-
mum flow rate.
MINICYL Regulator
This compact general purpose regulator
has many laboratory applications
including air-drying glassware, sparging
or evaporating solutions, and control-
ling pneumatic valves. It is constructed
of lightweight aluminum with an elas-
tomer diaphragm. Includes a 0–60 psig
(0-414 kPa) gauge and either
1

1
/

-inch tube fittings.
Cylinder ValveWrench
This specially-designed wrench enables easy opening of cylinder
valves that are fitted with a hand wheel. It is also suitable for
removing difficult cylinder caps.
Universal Cylinder Wrench
Use this versatile wrench for tightening gauges and gas regulator
CGA fittings to cylinder outlets and pipe thread connections.

Cylinder Holders, Wall Mounted
Prevent serious injuries! These holders are designed to prevent
free-standing gas cylinders from tipping over and injuring per-
sonnel. The cast aluminum holder can be secured to a wall or the
side of a work bench. Each mount will secure a cylinder 4-15
inches in diameter.
Noncorrosive Gases
High-purity automatic
switchover systems pro-
vide a continuous supply
of high purity gas to the
laboratory, process, or
instrument, to allow you
to replace a depleted gas
source without interrup-
tion in the gas supply. Continuous gas supply is achieved by set-
ting the two regulators at slightly different pressures and dis-
charging one side of the system at a time. These models include
flexible, all-stainless-steel pigtails with armor casing. The CGA
connection on each pigtail has a check valve in the gland to pre-
vent contamination and minimize purging requirements.
Protocol Station
The protocol station is designed
for convenient wall mounting
of high-purity gas regulators.
Wall mounting provides ease of
use, prevents gas regulator dam-
age, and improves safety. Either
chrome-plated brass or 316
stainless steel option is complete with a 3-foot, flexible, all-stain-
less-steel pigtail with armor casing. The CGA connection on the
pigtail has an integral check valve in the gland to prevent
contamination during cylinder changeout.
