The newest model of the EchoTherm line of programmable digital stirring hot plates, Model HS65, comes with five stirring positions. It is suitable for use in chemical, pharmaceutical, environmental, biochemical, and other laboratories where reproducible, accurate, hands-off sample preparation and experimentation are needed. Programming is done through a front panel membrane switch and full-functioned custom liquid crystal display. The unit can store 10 programs in memory of as many as 10 steps each where each step is a temperature, temperature ramp rate (if wanted), stirring speed and time. Torrey Pines Scientific
