The Decolorization Shaker SK-D700/SK-R800 is a precision benchtop agitation system designed for controlled mixing applications in research laboratories. This dual-model platform offers both 3D universal motion (SK-D700) and horizontal cyclotron motion (SK-R800) to accommodate diverse sample preparation requirements across multiple research disciplines.
Featuring high precision stepper motor control with ±1rpm accuracy, the system provides consistent agitation across a speed range of 10-100rpm (SK-D700) and 30-300rpm (SK-R800). The LCD display enables precise timing control up to 99.59 hours, while the robust 320×320mm platform accommodates up to 5kg of samples. Both models utilize specialized motion profiles - the SK-D700 employs 9° inclination with 25mm vertical displacement, while the SK-R800 delivers 20mm diameter circumferential motion for applications requiring horizontal mixing dynamics.
How It Works
The Decolorization Shaker employs precision stepper motor technology to generate controlled mechanical agitation through two distinct motion profiles. The SK-D700 model creates 3D universal motion by combining vertical oscillation (25mm amplitude) with a 9° inclination angle, producing a complex mixing pattern that enhances mass transfer in multi-phase systems. The SK-R800 model generates horizontal cyclotron motion with a 20mm diameter circumferential pattern, ideal for applications requiring gentle lateral mixing.
High precision stepper motor control maintains speed accuracy within ±1rpm across the operational range, ensuring reproducible agitation conditions essential for quantitative analytical procedures. The programmable timing system allows extended operation up to 99.59 hours, enabling unattended processing of samples requiring prolonged extraction or incubation periods.
The robust platform design accommodates various sample containers while maintaining stable operation at maximum 5kg loading. LCD display provides real-time monitoring of speed and timing parameters, allowing researchers to document exact agitation conditions for protocol standardization and regulatory compliance documentation.

Practical Tips
Verify speed accuracy monthly using a calibrated tachometer at low, medium, and high speed settings.
Why: Maintains traceability for regulatory compliance and ensures consistent results across extended use periods.
Clean platform surface after each use and inspect for residue buildup that could affect container stability.
Why: Prevents cross-contamination between samples and maintains proper platform balance during operation.
Document speed, time, and container arrangement for each application to develop standardized protocols.
Why: Enables method validation, facilitates technology transfer, and ensures reproducible results across operators.
Ensure containers are properly secured and weight is evenly distributed across the platform before operation.
Why: Prevents container displacement and maintains unit stability, especially at higher speeds and extended run times.
Run empty platform for 5 minutes before use to verify smooth operation and absence of unusual vibrations.
Why: Identifies potential mechanical issues that could affect agitation consistency and compromise experimental results.
If speed fluctuations occur, check for platform overloading or uneven weight distribution before suspecting motor issues.
Why: Most speed control problems stem from improper loading rather than motor malfunction, enabling quick resolution.
For volatile solvents, use appropriate container closures and consider fume hood placement for safety.
Why: Prevents vapor accumulation and exposure while maintaining proper ventilation for extended operation periods.
