The MRC Laboratory Digital Aluminum Top Hotplates Stirrers are designed for years of reliable and trouble-free performance, even with 24/7 continuous operation. Made with a heavy-duty aluminum hotplate top, a made in Germany, maintenance free AC motor, a rugged housing, and digital controls, to provide exceptional value, performance, and reliability in industrial and laboratory hotplate stirrers.

Applications

• General lab and microbiology heating and stirring requirements,
•  Distillations, extractions & digestions,
• Aqueous and general reagent heating,
• Media preparation,
• Liquid evaporation,
• Semiconductor baking,
• Acid/Base digestions (trace metal analysis),
• Sample drying,
• Microscale chemistry,
• Heat TLC plates,
• Paste, adhesive & solder (warming/curing),
• Solubility and viscosity studies,
• Reaction optimization.

Features  

• Provides gentle or vigorous mixing with wide range of stirring speeds,
• Strong magnetic coupling for continuous use in viscous liquids,
• Aluminum Top Plate: Easy to clean and chemically resistant, with excellent thermal conduction to uniformly distribute heat over the entire heating surface, excellent temperature uniformity and precise temperature stability,
• PID microprocessor controller with easy setup and operation: 

• Provides digital temperature display (°F or °C) with illuminated readout for quick and easy observation,
• Precise temperature regulation over full temperature range, even at low settings close to the ambient, making it ideal for processing delicate materials at low temperature,
• Closed loop feedback control of temperature range by PID microprocessor, to monitor sudden changes, prevents boil-overs, destroyed samples and lost time,
• Temperature may be controlled either at the plate surface by internal sensor, or by signal from a thermocouple immersion probe,
• Digital timer and ramp to temperature function,
• Digital set-point and read-out of actual temperature, 
• Previously stored set point in memory displayed when unit is turned on.
• Hydraulic thermostat hotplate sensor to minimize thermal overshoot and undershoot,
• Safety shut down of heater in the event of broken sensor,
• Illuminated 'Heat On' indicator for safety,
• Thermal radiation shields below top plate for safety and reliability, even during continuous high temperature operation,
• Aluminum housing with chemically resistant paint, 
• Sturdy set screw support device at the rear of the base to holds standard labware mounting rod.
