The Multi-position Magnetic Stirrer provides simultaneous stirring for up to six vessels with independent speed control across positions. The unit employs a DC brushless motor system delivering consistent rotation from 50 to 1600 rpm across a 369×269 mm working plate. The integrated timer function supports extended protocols up to 99 hours and 59 minutes, enabling unattended operation for lengthy mixing procedures.
The 25W stirring power accommodates vessels up to 1L capacity per position, suitable for diverse laboratory mixing applications including buffer preparation, sample homogenization, and solution preparation. The unit operates within ambient conditions of 5-40°C and up to 80% humidity, providing reliable performance in standard laboratory environments.
How It Works
The multi-position magnetic stirrer operates through electromagnetic field generation beneath each stirring position on the working plate. When a magnetic stir bar is placed in a vessel above each position, the rotating electromagnetic fields cause the stir bars to rotate synchronously. The DC brushless motor system provides precise speed control and eliminates maintenance issues associated with brushed motors.
Each position generates an independent magnetic field, allowing different vessels to be stirred at the same speed setting while maintaining consistent rotation across all active positions. The 25W power output distributes across active positions, providing sufficient magnetic coupling for stir bars up to standard laboratory sizes in vessels containing up to 1L volume per position.

Practical Tips
Verify speed accuracy using a tachometer or strobe light at regular intervals, particularly at commonly used speed settings.
Why: Ensures consistent mixing parameters across protocols and between different experimental sessions.
Clean the working plate surface regularly with appropriate solvents to remove chemical residues that could affect magnetic coupling.
Why: Chemical buildup can create distance between vessel and magnetic field, reducing stirring efficiency.
Start stirring at low speeds and gradually increase to prevent stir bar decoupling and solution splashing.
Why: Prevents sample loss and ensures stable magnetic coupling throughout the mixing protocol.
Use stir bars approximately one-third to one-half the diameter of the vessel bottom for optimal mixing efficiency.
Why: Proper stir bar sizing ensures effective solution movement without excessive turbulence or vessel contact.
If stir bars decouple frequently, check for ferromagnetic interference from nearby equipment or vessel materials.
Why: External magnetic fields or ferromagnetic materials can disrupt the coupling between motor and stir bar.
Ensure vessels are stable and properly centered before starting operation, especially when using the timer function.
Why: Prevents vessel displacement during extended unattended operation that could lead to spills or equipment damage.
Document stirring speed and duration as part of protocol parameters for reproducible results across experiments.
Why: Mixing conditions significantly affect solution homogeneity and can impact experimental outcomes and reproducibility.
Inspect stir bars regularly for chips or deformation that could affect mixing performance or damage vessels.
Why: Damaged stir bars create uneven mixing patterns and may scratch glassware or create sample contamination.

Background reading relevant to this product:
Can different positions be operated at different speeds simultaneously?
All positions operate at the same speed setting. The unit provides uniform stirring across all active positions but does not offer independent speed control per position.
What is the maximum stir bar size that maintains coupling?
Consult product datasheet for specific stir bar compatibility. Generally, standard laboratory stir bars up to vessel diameter maintain coupling with the 25W power output.
How does the timer function operate during power interruption?
Timer settings are not retained during power interruption. Protocols requiring uninterrupted timing should include backup power considerations.
What vessel materials are compatible with magnetic stirring?
Non-magnetic materials including glass, plastic, and ceramic vessels are compatible. Avoid ferromagnetic containers that interfere with magnetic field transmission.
Can the unit handle viscous solutions effectively?
The 25W power output accommodates moderate viscosity solutions. Very viscous samples may require lower speeds to maintain stir bar coupling or alternative mixing methods.
What maintenance is required for the brushless motor system?
Minimal maintenance required due to brushless design. Regular cleaning of the working plate and periodic inspection of magnetic coupling performance are recommended.
Are replacement parts available for long-term use?
Standard replacement components including stir bars and accessories are typically available. Contact ConductScience for specific part availability and compatibility.
