The Model M765 is available in 3 basic configurations 1 Cryogenic and 2 mechanically cooled designs.  All 3 designs come standard with a castered stand. 

The M765 is a high performance Cryogenic chamber with high temperature ramp rates.

The M765M and M765MM are mechanically cooled chambers that are available with a number of compressor configurations depending on your cooling  requirements.

Model C controller is standard
Model C4 programmable controller is optional

Models Description
M765 Cryogenic with L-CO2 or L-N2
M765M Single Stage Refrigerated system
M765MM Cascade Refrigerated system

Single Zone Shock Chamber

The M765 chamber can be configured as a high performance single zone shock chamber that meet the requirements of MIL SPEC 202, Method 107 testing, able to achieve -170°C.  Configured with the optional Shock package, the chamber features a top mounted C4 controller and maintains a very compact footprint, and is supplied with hinged lift off door.  Click here to learn more

§  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.
