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 |

| M33M | Single Stage Refrigerated system |
| M33MM | Cascade Refrigerated system |
A castered stand (with or without bottle rack) is available for easy roll around use.
