Motorless Magnetic Stirrer
Product Code : EL-LS-10749
Quick answer: The motorless magnetic stirrer turns the stirrer bar with an electronically generated magnetic field, so there is no motor, bearing or moving part to wear out, which suits continuous long-duration stirring. It offers stepless speed from 100 to 900 rpm, a clockwise or counter-clockwise selector and a high/low mode for different viscosities. Lab Exports manufactures it in Delhi for school, college, research and industrial laboratories.

How the motorless stirrer works
Instead of a motor spinning a magnet, electromagnets under the plate are switched in sequence to create a rotating magnetic field, and the stirrer bar (magnetic follower) in the vessel turns with it. With nothing mechanical to wear, the stirrer can run for long periods in cultures, slow reactions, solubility studies or equilibrium experiments without bearing noise or wear.
The high/low mode matches the drive to the liquid: low for thin aqueous solutions, high for thicker, more viscous ones. Reversing direction with the selector breaks up a steady vortex and mixes suspensions more thoroughly. If the follower is knocked off-centre, the reset button re-centres it and returns to the previously set speed.
- Place the vessel centrally and add the stirrer bar.
- Select high or low mode to suit the viscosity and choose the direction.
- Set the speed between 100 and 900 rpm.
- Press reset if the follower loses its position.

Frequently asked questions
What is a motorless magnetic stirrer?
A stirrer that turns the bar with an electronically generated rotating magnetic field instead of a motor, so no moving parts or bearings wear and it suits continuous use.
What speed range does it have?
Stepless variable speed from 100 to 900 rpm, with high and low modes for different viscosities.
What happens if the stirrer bar is knocked off-centre?
The reset button re-centres the magnetic follower and restarts stirring at the previously set speed.
