New programmable hot plate with precise temperature control

Torrey Pines Scientific, Inc. announces its new EchoTherm™ Programmable Digital Stirring Hot Plate for use in chemical, pharmaceutical, environmental, biochemical, and other laboratories where reproducible, accurate chemical reaction control and sample preparation are essential.

With the user-friendly EchoTherm™ Model HS40, programming is done through the front panel membrane switch and full-function custom liquid crystal display. The unit can store 10 programs in memory, each with up to 10 steps, where each step is a temperature, temperature ramp rate, stirring speed, and time. Each program can be set to repeat automatically from 1 to 98 times, or infinitely if desired. All programs are stored electronically.

Heater plates are 8" (20.3 cm) x 8" (20.3 cm) white, solid ceramic glass for excellent chemical resistance and quick heating. The plate surface can be heated from ambient to 450°C in less than 3 minutes. Plate surface temperature or solution temperature can be controlled directly to within 1°C of the target. Accuracy is 1% of the reading using platinum RTD circuitry. The units are supplied with temperature calibration certificates traceable to NIST.

Stirring speed ranges from 100 to 1500 rpm and is controlled by an optical coupler to within 10 rpm. A countdown timer with alarm, user-settable Auto-Off, and an RS232 I/O port are standard. Various sample probes are available as accessories. The Model HS40 is available in 100, 115, and 230 VAC, 50/60 Hz models. All units are ETL, CSA, and CE certified.
