New Stirring Hot Plate Stores 10 Programs in Memory
Aug 25 2006
Ideally suited for use in chemical, pharmaceutical, environmental, biochemical, and other laboratories where reproducible, accurate, hands-off sample preparation and experimentation are a must.
With the easy to use EchoTherm? Model HS40, programming is done through the 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, stirring speed and time. Each program can be made to repeat itself automatically from 1 to 98 times or infinitely if wanted. 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 450Â°C in less than 3 minutes.
Plate surface temperature or solution temperature can be controlled directly using the appropriate PID control loop to 1Â°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 is 100 to 1500 rpm and controlled by optical coupler to 10 rpm. Count down timer with alarm and user settable Auto-Off are standard.
