Model C76 is a ruggedly built controlled-temperature water bath shaker designed for continuous-duty orbital shaking, 24 hours a day, year-in and year-out. Microprocessor-controlled, the C76 achieves self-correcting feedback control of temperature and shaker speed. The advanced design comprises pushbutton setpoints, self-diagnostic status lights and alarms that warn of any functional deviation from control tolerances. With a broad speed range from 50 to 300 rpm, the C76 imparts gentle stirring for hybridization and gel staining, and the growth of shear-sensitive cells, as well as vigorous agitation and aeration for intense growth of bacterial cultures.
