Purifiers (Oxygen Traps)
 The OxiClear™ Gas Purifiers are oxygen-absorbing gas purifiers with high efficiency and
low resistance to gas flow. OxiClear™ Gas Purifiers are primarily designed for
applications involving gas chromatography, glove boxes and anaerobic experiments.
They remove oxygen and trace amounts of water and organics from inert carrier gasses
such as nitrogen, helium and argon. OxiClear™ purifiers are efficient to less than 5 ppb
when the incoming oxygen concentration is 15 ppm or less. Furthermore, all models can
withstand temperatures up to 100°C. All models are fitted with 60 micron stainless steel frits.
The OxiClear™ Gas Purifiers are offered in a large variety of designs and configurations:
Disposable purifiers
The OxiClear™ Disposable Gas Purifier is offered in th "inline" configuration,
with either 1/4" or 1/8" brass mal tube compression fittings. It is capable of
purifying the contents of 4-5 standard cylinders of 300 cubic feet, eas ily removing
oxygen from inert carrier gasses down to less than 5 ppb. Offering a very low resistance
to gas flow, .03 psi/(cc/second), the OxiClear™ Disposable Gaf Purifier will deliver
100 cc/second at a pressure drop o: only 0.3 psi. Flow rate to 5 liters per minute.

- Indicating Oxygen Traps (purifiers)
Now you are sure when your O2 purifier is expended and needs replacement
(or refilling, if using a refillable model). Simply install the Indicating Oxygen Trap
after the OxiClear™ purifier. When the color of the Indicating Oxygen Trap turns from
light green to grey, it is time to change both the purifier and indicator. No more
calculating or guesswork.
This safe, compact unit has a capacity of 40 cc of pure oxygen; it will remove
oxygen from a full 200ft3 cylinder helium with 10 ppm oxygen (or several cylinders
of higl purity helium). The heavy-walled inner glass tube of cats is protected from
accidental breakage by the outer plasti tube. Maximum pressure is 100 psi. The
Indicating Oxyj Trap is delivered in the active state, filled with helium. I
recommended that the trap be purged before use with the gas you will be using.
