LABORATORY GAS DRYING UNIT
The DRIERITE Laboratory Air and Gas Drying unit is an all-purpose drier.
This unit is suitable for most laboratory applications. It will dry air to a
dew point of -100° F at atmospheric pressure or pressures up to 90 psig.
A simple connection by rubber hose to the bottom inlet of the dryer provides
an immediate flow of dry air or gas. This unit is also available with 1 /8
inch SS NPT fittings (Stock No. 26840). Plastic coated mounting clips may be
purchased separately. Continuous flows are possible with two units in the
line and the necessary valves so that the exhausted column may be refilled
while the alternate column remains in use.
Note: Do not use this plastic column in
the presence of vapors or liquids containing phosphate esters, synthetic
lubricants, hydrocarbon solvents, methanol, acetone, lacquer solvents, or
APPLICATIONS: The Laboratory Gas Drying Unit can be used
anywhere to provide dry air or gas for applications such as: blanketing,
sample preparation, instrument protection, reaction mixtures, purging,
vacuum release, venting with dry air.
The Indicating DRIERITE
gives constant visual assurance of active desiccant. When active, Indicating
DRIERITE is a distinct blue color. When exhausted, it turns pink. The zone
between the two colors in the column may be a purple color and should be a
sharp narrow band when the flow rate is at equilibrium. Regeneration will
restore the drying capacity.
The Laboratory Gas Drying
Unit can be refilled with fresh DRIERITE, or the DRIERITE granules can be
removed from the column and regenerated. See
Regeneration of Drierite Desiccants
Column is molded polycarbonate.
Desiccant supports and coil spring are stainless steel.
Polycarbonate cap is fitted with o-ring gasket.
