Hot plates (or Magnetic stirrer) are electronic devices used to uniformly heat the liquid with or without stirring it. The principle of working is same as in the one used in a kitchen, its usage is in chemistry and biology lab. A stir bar (or beads or ‘flea’) is immersed into the liquid and the device generates a magnetic field which causes the bar to rotate and thereby generating a vortex stirring the liquid. The temperature of the hot plate and the frequency of rotation (rpm) can easily be adjusted manually. The device is available in multiple dimensions. The manufacturer/supplier provides an operation manual with all specifications details. Calibration and application details can be seen in the manual.

 

Commercial Hot Plates are available with digital display, corrosion resistant plate, rotation frequency range 100 to 1000 rpm.
