Models M33, M33M and M33MM are very compact temperature chambers. Models M33M and M33MM are the smallest footprint mechanically refrigerated chambers available anywhere. With the refrigeration unit mounted under the temperature chamber workspace, the chambers' small footprint is equally at home on a bench top or in a 19" rack. A lift-off hinged door is standard for all models and a pull-off door is available.

Standard with a Model C controller, Model C4 programmable controller is optional
Models Description
M33 Cryogenic with L-CO2 or L-N2
M33M Single Stage Refrigerated system
M33MM Cascade Refrigerated system

A castered stand (with or without bottle rack) is available for easy roll around use.

§  Cooling Rate

Cryogenic rates are highly dependent upon coolant type
(L–N2 or L–C02), pressure, and quality.  For more information download or request a copy of our brochure on Cryogenic Cooling

Mechanical refrigeration (not available on all chambers) rates are dependant on refrigeration system chosen and other factors.
Note: Cryogenic boost can be added to mechanically refrigerated systems to speed transition temperatures

    Heating Rate

Temperatures shown are for typical heaters. 
Faster and slower rates available.
