 MRC Labs Digital Aluminum Top Hotplate Stirrers

The MRC Laboratory model MHK-4D is a heavy duty ceramic top hotplate stirrer which combines performance, pricing and reliability to provide an exceptional value in laboratory equipment. It provides excellent temperature uniformity and precise temperature stability, making it ideal for processing of delicate materials at low critical temperatures and for all general laboratory heating procedures. Designed for years of reliable and trouble-free operation with features generally found only in a much more expensive laboratory hotplate.

 Features 

• Quiet direct drive motor with analog control of stirrer magnet,
• Temperature sensitive stepless analog control to set and maintain stable temperature,
  
• Strong magnetic coupling for continuous use in viscous liquids,
• Digital timer and ramp to temperature function,

• Digital set-point and read-out of actual temperature,
• Temperature may be controlled either at the plate surface by internal sensor, or by signal from a thermocouple immersion probe,
• Power to the heater is shut-down in the event of broken sensor,
• Hydraulic thermostat to minimizes thermal overshoot and undershoot,
  
• Excellent thermal conduction evenly distributes heat for uniformity over the entire heating surface,
• Rapid heating to reach 500°C maximum in 8 minutes,
  
• Illuminated 'Heat On' indicator for safety,
• High impact ceramic for strength and acid and alkali resistance, 
  
• Ceramic top plate remains flat at temperature to ensure maximum heat transfer,
• Reflective white top for easy sample viewing,
  
• Cast aluminum case with chemically resistant paint,
• Thermal radiation shields - safe and reliable, even during continuous high temperature operation,
• Sturdy set screw support device at the rear of the base to hold standard labware mounting rod.
