Torrey Pines Scientific has released its Echotherm digital hot plates and digital stirring hot plates.
The Echotherm models HP51 and HS51 digital hot plates and digital stirring hot plates are designed for large samples.
The units feature membrane keyboards and liquid crystal displays, where all parameters are continuously visible.
These units can store two of the user's favourite settings in memory for instant recall and use at any time.
They are suitable for use with large samples in chemical, pharmaceutical, environmental, biochemical, electronic and other laboratories where temperature accuracy and reproducible sample preparations are a must.
Tops are available in a choice of chemically resistant ceramic or milled-flat cast aluminum.
Both tops are 12in x 12in square.
The ceramic top has 1,400W heaters.
The aluminum top has a 1,200W heater and is recommended for working with solids directly on the heater plate surface.
Temperatures can be set up to 450C on the ceramic topped units and to 400C on cast aluminum 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 1,500rpm.
The built-in timer can be set to 99 hours and is readable to 1s.
These units have 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, 50/60Hz models.
