The ConductScience Microplate Mixer delivers precise orbital mixing for microplates in laboratory applications requiring gentle yet effective sample agitation. This benchtop instrument utilizes a brushless DC motor to provide consistent 4.5mm orbital motion across a speed range of 0-1500 rpm for single microplates and 0-1000 rpm when accommodating double microplate configurations.
The compact design features IP21 protection rating and operates reliably within standard laboratory environmental conditions (5-40°C, 80% RH). The 10W motor output provides sufficient torque for consistent mixing while maintaining low power consumption at 20W total. The scale speed display allows for reproducible experimental protocols, and the universal AC100-240V power supply ensures global laboratory compatibility.
How It Works
The microplate mixer operates on orbital motion principles, where the platform moves in a circular pattern with a fixed 4.5mm diameter. This orbital motion creates controlled fluid dynamics within microplate wells, generating convective currents that promote mixing without the harsh acceleration forces associated with linear shaking methods.
The brushless DC motor provides precise speed control and eliminates electromagnetic interference common with brush-type motors. The 10W output delivers consistent torque across the entire speed range, while the motor's feedback control system maintains stable orbital motion even as sample viscosity varies. The IP21 protection rating ensures reliable operation in typical laboratory environments where dust and occasional liquid exposure may occur.

Practical Tips
Verify speed settings with empty plates before adding samples to ensure proper orbital motion without excessive vibration.
Why: Prevents sample spillage and ensures reproducible mixing conditions across different experimental protocols.
Clean the platform regularly with laboratory disinfectants and ensure ventilation openings remain clear of dust buildup.
Why: Maintains motor cooling efficiency and prevents contamination between different sample sets.
Start mixing at lower speeds and gradually increase to optimal settings to prevent sudden fluid displacement in wells.
Why: Minimizes risk of sample loss and cross-contamination between adjacent wells during protocol initiation.
If excessive vibration occurs, verify the platform is properly secured and total load weight is within 0.5kg specification.
Why: Prevents mechanical damage and ensures stable orbital motion necessary for consistent mixing results.
Allow samples to settle briefly after mixing before optical measurements to eliminate air bubbles that may affect absorbance readings.
Why: Ensures accurate spectrophotometric measurements by eliminating optical interference from entrained air.
Use sealed plates or plate sealing films when mixing volatile solvents or potentially hazardous biological samples.
Why: Prevents vapor exposure and sample evaporation while maintaining mixing effectiveness in controlled environments.
Match mixing time and speed to sample viscosity - use lower speeds for longer duration with viscous solutions.
Why: Achieves thorough homogenization without generating excessive heat or shear forces that could affect sample integrity.
Inspect platform attachments regularly for wear and ensure secure mounting before each use session.
Why: Prevents platform detachment during operation and maintains consistent orbital motion characteristics.

Compliance
What is the maximum sample volume per well that can be mixed effectively?
The 4.5mm orbital diameter is optimized for standard microplate well volumes up to 200-300μL. Consult product datasheet for specific volume recommendations based on plate format and mixing requirements.
Can the mixer accommodate different microplate formats beyond standard 96-well plates?
The platform can accept various microplate formats including 384-well and deep-well plates, provided the total weight including samples remains within the 0.5kg maximum load capacity.
How does the speed range change when using double microplate configuration?
Speed range reduces from 0-1500 rpm (single plate) to 0-1000 rpm (double plate) to maintain stable orbital motion and prevent mechanical stress with increased load.
Is the mixer suitable for temperature-controlled applications?
The mixer operates in ambient temperatures from 5-40°C but does not provide active heating or cooling. For temperature-controlled mixing, use within an incubator or temperature-controlled chamber.
What maintenance is required for the brushless motor?
Brushless motors require minimal maintenance - periodic cleaning of external surfaces and ensuring adequate ventilation. No brush replacement or internal maintenance is needed.
Can the mixing speed be programmed or automated?
The current model features manual speed control via scale display. For automated protocols, integration with external control systems would require additional interface hardware.
How does orbital motion compare to linear shaking for microplate mixing?
Orbital motion provides gentler mixing with reduced risk of sample spillage and foam formation compared to linear shaking, making it preferred for cell cultures and sensitive assays.
