BackpressureGasRegulator
Capillary GC inlet systems have backpressure regulators to
maintain a constant upstream pressure and rapidly respond to
catastrophic leaks. The 0–60psig (0-414 kPa) operating range is
sufficient to operate a 105 m, 0.25 mm ID column at its opti-
mum flow rate.
MINICYLRegulator
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

-inch tube fittings.
CylinderValveWrench
This specially-designedwrench enables easyopeningof cylinder
valves that are fitted with a hand wheel. It is also suitable for
removingdifficult cylinder caps.
UniversalCylinderWrench
Use this versatilewrench for tightening gauges and gas regulator
CGA fittings to cylinder outlets andpipe thread connections.

CylinderHolders,WallMounted
Prevent serious injuries! These holders are designed to prevent
free-standing gas cylinders from tipping over and injuring per-
sonnel.Thecast aluminumholder canbe secured toawall or the
side of a work bench. Each mount will secure a cylinder 4-15
inches indiameter.
CriticalPurityAutomaticSwitchoverSystem for
NoncorrosiveGases
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 achievedby set-
ting the two regulators at slightly different pressures and dis-
charging one side of the system at a time. Thesemodels include
flexible, all-stainless-steel pigtails with armor casing. The CGA
connectionon eachpigtail has a check valve in the gland topre-
vent contamination andminimize purging requirements.
ProtocolStation
Theprotocol station isdesigned
for convenient wall mounting
of high-purity gas regulators.
Wallmounting provides ease of
use,preventsgas regulatordam-
age, and improves safety. Either
chrome-plated brass or 316
stainless steel option is completewith a3-foot, flexible, all-stain-
less-steel pigtail with armor casing.TheCGA connectionon the
pigtail has an integral check valve in the gland to prevent
contaminationduring cylinder changeout.
