The Hotplate Magnetic Stirrer MS Series combines precision heating and magnetic stirring capabilities in a single benchtop instrument designed for laboratory sample preparation and reaction monitoring. Featuring a 184×184mm glass ceramic work plate and brushless DC motor technology, this stirrer accommodates vessels up to 20L capacity while providing uniform heat distribution and consistent stirring performance.
The stainless steel construction with ceramic coating ensures chemical resistance and thermal stability across demanding laboratory protocols. The 18W brushless motor delivers reliable magnetic coupling for extended operation periods, making this instrument suitable for routine analytical procedures, synthesis reactions, and sample dissolution workflows requiring precise temperature and agitation control.
How It Works
The hotplate magnetic stirrer operates through electromagnetic induction heating of the glass ceramic work plate surface, providing uniform temperature distribution across the 184×184mm working area. The heating element beneath the ceramic surface generates controlled thermal energy that transfers efficiently to laboratory vessels while maintaining temperature stability during extended operations.
Magnetic stirring is achieved through a brushless DC motor system that rotates a magnetic field beneath the work plate. This rotating field couples with magnetic stir bars placed inside sample vessels, creating consistent rotational motion without direct mechanical contact. The 18W motor provides sufficient torque to maintain stirring action in viscous solutions and large volume containers up to 20L capacity.
The glass ceramic work plate material offers superior chemical resistance and thermal shock tolerance compared to metal surfaces, while the stainless steel housing with ceramic coating provides durability against corrosive laboratory environments. The brushless motor design eliminates mechanical wear points, reducing maintenance requirements and ensuring long-term operational reliability.

Practical Tips
Verify temperature accuracy using calibrated thermometers placed in representative sample volumes before critical analytical procedures.
Why: Ensures measurement traceability and protocol compliance for temperature-sensitive reactions and dissolution studies.
Clean the glass ceramic surface with appropriate solvents immediately after use to prevent residue buildup that could affect heat transfer.
Why: Maintains uniform temperature distribution and prevents contamination of subsequent samples.
Select stir bar size to approximately 2/3 of the vessel diameter for optimal mixing efficiency in different container geometries.
Why: Provides adequate agitation while preventing bar decoupling during high-speed stirring operations.
Allow adequate cooling time before handling vessels or cleaning the work plate surface after high-temperature operations.
Why: Prevents thermal injuries and thermal shock damage to glassware during routine laboratory procedures.
Monitor stirring consistency by observing vortex formation and stir bar rotation stability throughout extended procedures.
Why: Ensures reproducible mixing conditions critical for analytical method validation and quality control testing.
Check for magnetic interference from nearby equipment if stir bar coupling becomes unstable during operation.
Why: External magnetic fields can disrupt motor performance and compromise stirring effectiveness in sensitive analytical procedures.
Position the unit away from vibration sources and ensure level installation for optimal magnetic coupling performance.
Why: Mechanical stability is essential for consistent stirring action and accurate temperature control during lengthy analytical procedures.
