The compact design with a footprint of 205 x 260 mm allows the use on crowded laboratory tables or under fume hoods. All three units feature a ceramic coated stainless steel plate highly resistant against strong acids and bases. The stirrer is equipped with a speed control knob for a range of 60 – 500 rpm. The heatplate of the SLH and SLHS has maximum power consumption of 500 Watts and is electronically controlled to prevent overcharging. Two control LEDs on the front plate light up when heating and stirring function are on.
