The Laboratory Air and Gas Drying unit is an all-purpose drier. This unit is suitable for most laboratory applications. It will dry air or inert gas to a dew point of -100 °F ( -73 °C ) 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. 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 drier in the presence of vapors or liquids containing phosphate esters, synthetic lubricants, hydrocarbon solvents, methanol, acetone, lacquer solvents, or other organics.
APPLICATIONS
The Laboratory Gas Drying Unit can be used anywhere to provide dry air or gas for applications especially for a glove box which requires drying gas with humunity (RH) < 2 %
Color Change
The Indicating desiccant constant visual assurance of active desiccant. When active, Indicating desiccant 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. The exhausted desiccant can be regenerated by heating it at 210°C for 2 hours ( better in vacuum oven ) and restore the drying capacity
