The magnetic stirrer and vortex breaker design help ensure isothermal conditions in this bath throughout its temperature range. Utilizing a liquid medium, the Multi Cool handles heat loads substantially larger than its liquid nitrogen counterparts and does not utilize expendable refrigerant. The Multi Cool is available with an on/off switch or an optional digital controller providing +/- 0.1C stability. Digital controller offers a temperature range of -80C to +100C and comes complete with RS-232 interface.
