    Type Hotplates

    Perform life science and biotechnology applications with the help of Thermo Scientific™ Super-Nuova™ Multi-Position Digital Stirring Hotplates, which offer four independently-controlled stirring positions on one heated, ceramic top. Including 4-function memory and a low-temperature adjustment ideal for life science and biotechnology applications, these stirrers are designed for labs with multiple users and require high-volume processing with unmatched performance, safety and controls.

    Operating Features

    • Microprocessor control ensures accurate and stable setpoints for temperature and stirring speed
    • Electronic feedback controls monitor either top plate surface or liquid temperature (when using external PTFE-coated probe, included) and adjust to setpoint
    • Single control knob controls heat and speed; lock feature prevents accidental changes
    • Digital display for temperature or rpm
    • Powerful motor and magnetic system prevent magnetic decoupling
    • Thermo Scientific™ Stir Trac™ breaking feature brings stir bar to an immediate stop for quick false removal and prevents runaway or decoupled stir bars
    • Temperature adjusts in 1° increments
    • Four user-defined temperature/speed memory keys recall settings
    • Calibration mode allows remote probe to be calibrated to external standards; probe can be programmed as a system (probe, control, display) at any user-selected temperature
    • Ceramic tops clean easily, resist chemicals and provide fast boiling time
    • Can be used in 0° to 27°C, 80% relative humidity, noncondensing environment
    • RS-232 port allows output of time count, temperature setpoint, top surface/remote probe temperature, stirring setpoint and actual speed

    Safety Features

    • Red HOT TOP warning light activates when heating surface is above 50°C (122°F); unit flashes HOT OFF until surface temperature falls to 50°C or below, even when heat control is turned off
    • Adjustable overprotection circuit limits top plate temperature, prevents runaway conditions
    • Rugged low-profile cast aluminum body provides stability and durability
    • Unit design protects internal components from accidental spills
    • Walk-away timer shuts off heating, stirring or both after preset user-defined interval


    • Detachable line cord and plug
    • 6 in. Type K probe
    • Stirring models also include stir bar
