Avoid Temperature Overshoot on Hotplate Magnetic Stirrers

Hotplate magnetic stirrers allow researchers to conduct mixing and stirring experiments at various temperatures to establish optimum processing recommendations for later scale-up.

While today’s hotplate magnetic mixers permit close control over temperatures set by lab technicians a malfunction in the unit’s thermostat could result in a potentially dangerous situation should a hotplate temperature overshoot occur.

CAT Scientific has addressed this concern in its MCS78 programmable hotplate magnetic stirrer video narrated by Steve Gold.

This short video describes how researches establish a set point control – that is, the desired temperature of the hotplate –  after which the MCS78 automatically programs an overshoot limit.  In the example, hotplate temperature was set at 120⁰C.  The unit’s processor instantly set 135⁰C as the shut-down temperature.

Should a malfunction occur allowing the hotplate to reach 135⁰C the MCS78 plate heater turns off but stirring continues until the sample reaches a safe temperature.
