CARLSBAD, CA . . . Torrey Pines Scientific announces its new EchoTherm™ Programmable Hot Plates and Digital Stirring Hot Plates for use with large samples in chemical, pharmaceutical, environmental, biochemical, electronic and other laboratories where temperature accuracy, accurate temperature profiles, ease of use, and reproducible sample preparations are a must.

The EchoTherm™ Models HP61 and HS61 Programmable Hot Plates and Programmable Stirring Hot Plates are rugged and designed for large samples. These units feature 10 program memory with 10 steps per program, temperature ramping, RS232 I/O port, membrane keyboard and full function liquid crystal display where all parameters are continuously visible.

Heater tops are available in ceramic or milled-flat cast aluminum. They are 12" by 12" square and have 1400 watt heaters. The aluminum top is recommended for working with solids directly on the heater plate surface.

Temperatures can be set to 450°C on the ceramic topped units and to 400°C on cast aluminum tops. The units are readable and settable to 1°C. Accuracy is 1% over the entire temperature range.

Temperature control is by PID software and is controlled to ±1°C or ±1ºF. Stirrer speeds can be set from 100 to 1500 rpm.

Temperature ramping can be set from 1ºC/hour to 450ºC/hour in 1ºC increments. The built-in timer can be set to 99 hours and is readable to 1 second.

The 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 230 VAC, 50/60 Hz models.
