Torrey Pines Scientific has introduced the Echotherm Digital Hot Plates and Digital Stirring Hot Plates, which use minimum bench space.
These units are ideal in chemical, pharmaceutical, environmental, biochemical, electronic and other laboratories where temperature accuracy, ease of use and reproducible sample preparations are a must.
The Echotherm Models HP50 and HS50 Digital Hot Plates and Digital Stirring Hot Plates are designed for samples of two litres or less.
They feature a membrane keyboard and full-function liquid crystal display where target and actual sample or plate temperature, stirring speed and timer, are continuously visible.
These units can store two of the user's settings in memory for instant recall and use at any time.
Heater tops are 6 x 6in square and feature energy-efficient 400W heaters.
The solid ceramic plate is white, chemically resistant and designed for use with solutions in a vessel.
The milled-flat cast aluminium top is recommended for working with solids directly on the heater plate surface.
Temperatures can be set to 450C on the ceramic topped units and to 400C on cast aluminium tops.
The units are readable and settable to 1C.
Accuracy is one per cent over the entire temperature range.
Temperature control is by PID software and is controlled to +/-1C or F.
Stirrer speeds can be set from 100 to 1500rpm.
The built-in timer can be set to 99 hours and is readable to one second.
It has an audible alarm with user settable auto-off for turning off the heater and stirrer when the timer counts down to zero.
The units are supplied with an immersion probe for controlling solution temperatures directly.
All units are available in 100, 115 and 230V AC, 50/60 Hz models.
