Most laboratories require simple, reproducible and accurate sample preparation and experimentation. Torrey Pines Scientific’s new EchoTherm Digital Stirring Hot Plate Model HS30 is for use in these environments. All functions are set through the front panel membrane keypad and the unit displays target and actual temperature, temperature ramp rate, stirring speed and time. Heater plates are 20.3 cm x 20.3 cm white solid ceramic glass for excellent chemical resistance and heating. The plate surface can be heated from ambient to 450°C in fewer than three minutes. Stirring speed is 100 to 1,500 rpm and controlled by optical coupler to 10 rpm. Torrey Pines Scientific Inc.
