Microprocessor Control Advanced electronics regulate both heating and stirring and bring samples to temperature quickly and efficiently. Precise speed control provides consistent stirring at all speeds. Powerful continuous duty motor delivers dependable and reliable stirring.
Control Panel Touch pad controls with easy-to-read, independent LED displays for temperature, speed, and time allow operator to view all settings at once. Provides repeatable and accurate results every time and is easily visible from outside fume hoods or across lab benches. 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.
Top Plate Material Ceramic tops feature a chemical resistant, reflective white top plate surface that is easy to clean. Durable aluminum tops will not crack or chip.
Low Profile Design Takes up minimal space and fits easily into fume hoods. Spill-resistant design channels fluids away from internal components.
Cool Touch Housing Housing is made of a heat resistant polymer that is not only cool to the touch, but is also chemical resistant.
Stir Protection If stirrer motor stops or fails, unit will automatically shut down heater.
Speed Ramping Feature Slowly increases motor speed for improved safety and enhanced coupling. Avoids splashing, improves spin bar control, and provides excellent low end speed control.
Audible Alarm In timed mode, alarm will sound when time reaches zero or when unit reaches set-point temperature.
