M90 Temperature Chamber

Pictures may show optional items
Click on the picture for details


 


 

The M90, M90M, & M90MM are compact temperature chambers. With the M90M the controller and refrigeration unit is mounted under the chamber workspace. With the M90MM the refrigeration unit is mounted under the chamber workspace, and the controller must be mount on the top or remotely. The M90's small footprint is equally at home on a bench top or on the optional castered stand. (The M90 chambers were formally known as the Sigma Super Cyclers.)

   Configure chamber for specific needs

Standard with Model C controller C4 programmable controller is optional
Models Description
M90 Cryogenic with L-CO2 or L-N2
M90M Single Stage Refrigerated system
M90MM 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.
