Operating Conditions

Your Mtops hot plate, stirrer or stirring hot plate is a general purpose heating and/or stirring plate designed for laboratory procedures requiring precise control of temperature and/or stirring speed. Your hot plate, stirrer or stirring hot plate has the following properties:

  1. Ceramic coated top plate: Ceramic coated top plate is corrosion proof, temperature
    resistant and resists aggressive fluids.
  2. Coated in a pure white plate allows for easy observation of sample color change during use.
  3. The top plate allows for quick thermal conduction and uniform surface temperature.
  4. This device uses an electronic Analog temperature controller to control temperature
  5. The Mtops Hot Plate Stirrers were designed to start and stop smoothly to prevent fluid
    spill over from rapid turnover and decoupling of stir bar.
  6. The Mtops hot plate has an electronic feedback control which will accurately maintain

Mtops hot plates, stirrers, and stirrer/hot plates are designed to provide safe functioning under
the following conditions:

  • Indoor use
  • Altitude up to 2000 meters (6,500 feet)
  • Ambient temperatures of 0°C to 40°C
  • Product should be placed on a flat surface at least 30.5 cm (12″) from walls, 122 cm (48″)
    from ceilings, and 30.5 cm (12″) from other hot plates if using multiple units.
  • Maximum relative humidity of 85% for temperatures up to 31°C, decreasing linearly to
    50% relative humidity at 40°C.
  • Pollution Degree 2: Any foreign matter that may accumulate on or within the product
    during normal use is not electrically conductive.
  • Installation Category II: Product is designed for connection to an electrical branch circuit
    inside a building with main supply voltage fluctuations not exceeding ±10% of the nominal voltage.

  2. Place your container or heating bath with magnetic stirrer bar. Stirrer bar should be placed in Center of hot plate.
  3. Turn Power Switch ON


Stirring Instructions


  1. Fill vessel with solution to be stirred.
  2. Place stir bar into vessel.
  3. Place vessel in the center of the top surface.
  4. Turn power switch ON. Then Hot Top Indicator Lamp will illuminate.
  5. Turn Stir Control Knob until the desired speed.
  6. Speed On Indicator Lamp will illuminate when the motor runs.
  7. Heating and stirring can be performed simultaneously on the MS300HS models which offer
    both heating and stirring functions.
  8. When the desired stirring is complete, turn the Stir Control Knob to “0” position. Allow stir bar to cease rotation before removing the vessel from the unit.
  9. Disconnect Main power cord from the unit.
  10. Keep the product dry and clean disconnecting Main power cord when the unit is not used for a long time.


  1. Range of speed control : 100~1500 RPM
  2. Speed control knob in extreme left (CCW) position stops operating.
  3. If motor does not run upon turning the knob, increasing until 100rpm or more

Please note that the viscosity of the stirred material will affect the ability of the stir bar to remain
coupled to the rotating ring magnet. Materials of high viscosity must be stirred at slower speed
