The M88MM is part of Sigma's new line of high performance chambers. These chambers are specifically designed and built with high performance components. The M88MM is a very compact high performance temperature chamber with the refrigeration unit mounted under the temperature chamber workspace, the chambers' small footprint is equally at home on a bench top or on an optional roll around stand.

Standard with Model C controller   Model C4 programmable controller is optional
Models Description
M88 Cryogenic with L-CO2 or L-N2
M88M Single Stage Refrigerated system
M88MM 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.
