Coy Laboratory Products catalyst boxes come in two styles, heated and unheated.

DIGITAL, HEATED
The heated catalyst box allows the whole glove box to be operated at a thermostat controlled temperature above ambient up to approximately 4O°C. The heating unit employs very reliable resistance type heaters. The glove box atmosphere is drawn in by a quiet, powerful fan motor, across the heaters and up through the desiccant and type D catalyst Stak-Paks*. This ensures a complete mix of the atmosphere to eliminate uneven temperatures and control humidity and oxygen levels. Therefore, with a double chamber, one may be used for the daily routine while the other is used as an incubator.

HIGH RANGE TEMP: An optional high range Digital Heated Fan Box may also be purchased to controll the temperature inside a COY glove box from ambient to 65°C.

UNHEATED
The unheated catalyst box is designed for those laboratories which do not require elevated temperatures in their anaerobic glove box. It functions in a manner similar to the heated box. Air is quietly drawn in and up through the desiccant and catalyst Stak-Paks*, thus ensuring a complete mix of the atmosphere to control humidity and oxygen levels.
