The MRC Laboratory MH Series are four position and six position hotplate stirrers with digital controls and aluminum top heater plates.  These units are designed for years of reliable and trouble-free performance, even with 24/7 continuous operation. Made with a heavy-duty aluminum hotplate top, and made in Germany, maintenance free AC motors, 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 (warning/curing),
• Solubility and viscosity studies,
• Reaction optimization.

Features

• Stirring and heating operations controlled individually,
• Provides gentle or vigorous mixing with wide range of stirring speeds,
• Strong magnetic coupling for continuous use in viscous liquids,
• Aluminum Top Plates: 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 controllers 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.
