When plate temperature rises above 50°C, a hot warning light flashes even if the unit is turned off or unplugged. All units feature an integral fixing point for a retort rod and are BioCote™ antimicrobial protected. Each stirring hot plate is custom designed. Select a favorite body color and choose between a glass ceramic or ceramic-coated aluminum plate surface. The glass ceramic plate is chemical resistant, easy to clean, and allows for very high plate temperatures; plus the white surface ensures good visibility of color changes.

The ceramic-coated aluminum plate offers excellent heat transmission, rapid heating with a 700-watt element, even temperature distribution, and is chemical resistant. The stirring hot plates also feature three different interface models—analog, digital, and premium. The digital interface model features a digital temperature setting. The set and actual temperature is shown on the seven-segment digital display. Stirring speed is displayed by a ‘hockey stick’ LED array with the lights progressively illuminating to represent the speed range. To achieve accurate sample temperature control up to 392°F (200°C), a digital temperature controller (sold separately) can be connected to the rear of the unit.
