Designed for applications that require repeatable results and superior temperature stability. These multi-purpose units are ideal for incubation and activation of cultures, enzyme reactions, immunoassays, melting/boiling points, and a wide variety of other laboratory procedures. Integral support rod holder with locking knob accepts optional External Temperature Probe Kit (available separately, Cat. No. 369-10655). Each of the models accepts separate interchangeable modular blocks, accommodating various tube sizes. Efficient heating due to close tube-and-block contact for maximum heat retention. Heaters require OHAUS modular heating blocks for operation. Modular blocks are sold separately (see accessories).

PID temperature control offers a temperature stability as low as +/- 0.1°C with a temperature uniformity as low as +/- 0.1°C. Samples are heated to temperature quickly and accurately. Temperature is adjusted in +/- 0.1°C increments. Touch pad controls with easy-to-read, independent LED displays for temperature, and time. Shows set-point and actual temperature. Timer will display elapsed time or, when programmed to user defined limit, will shut off unit when time reaches zero. Display will show last used settings, even after power has been turned off. Temperature calibration mode allows user to calibrate unit to an external temperature device. Hot warning symbol light is illuminated when the temperature is above 40°C. If the unit exceeds the set temperature by 10°C the unit will automatically stop heating. In timed mode, alarm will sound when time reaches zero and when unit reaches set-point temperature. Units can be run in conditions from 18 to 33°C (64 to 91°F), 20% to 80% relative humidity, non-condensing. Units include a detachable, 3-wire cord and plug.
