The Table Top Shaker is a precision benchtop instrument designed for controlled agitation of samples in laboratory environments. This rotatory shaking platform features a multidimensional drive system with PID controller technology, delivering consistent orbital motion across a speed range of 20-300 rpm with ±1 rpm accuracy. The system accommodates an 800×600mm tray platform, making it suitable for processing multiple samples simultaneously in various container formats.
The instrument incorporates an LCD display for real-time monitoring of operational parameters and offers programmable timing control up to 9999 hours. With its adjustable amplitude range up to 50mm diameter, the shaker provides versatile agitation conditions for applications ranging from cell culture maintenance to extraction protocols and sample preparation procedures across multiple research disciplines.
How It Works
The Table Top Shaker operates through a multidimensional drive mechanism that generates controlled rotatory motion across the platform surface. The PID (Proportional-Integral-Derivative) controller continuously monitors and adjusts motor speed to maintain precise orbital motion within ±1 rpm of the setpoint. This closed-loop control system compensates for load variations and ensures consistent agitation regardless of sample weight distribution across the platform.
The orbital motion pattern creates a centrifugal force that maintains samples in constant circulation while preventing settling or stratification. The variable amplitude adjustment (up to 50mm diameter) allows researchers to optimize mixing intensity for different sample types and container geometries. The multidimensional drive system distributes mechanical stress evenly across the platform, enabling uniform agitation of multiple samples simultaneously while minimizing vibration transfer to the surrounding work surface.

Practical Tips
Verify speed accuracy monthly using a tachometer at low, medium, and high speed settings across the 20-300 rpm range.
Why: Maintains measurement traceability and ensures reproducible experimental conditions over time.
Clean the platform surface with appropriate laboratory disinfectants after each use and inspect mounting hardware quarterly.
Why: Prevents cross-contamination between samples and maintains mechanical integrity of the drive system.
Distribute sample weight evenly across the platform and secure all containers to prevent movement during operation.
Why: Ensures uniform agitation and prevents mechanical stress that could affect speed accuracy or cause sample spillage.
If speed fluctuations occur, check for unbalanced loads and verify the platform is properly secured to the drive mechanism.
Why: Unbalanced operation can overwhelm the PID controller and lead to inconsistent agitation parameters.
Record actual speed and amplitude settings along with timing parameters in experimental documentation for reproducibility.
Why: Enables accurate protocol replication and troubleshooting of inconsistent results between experimental runs.
Ensure adequate clearance around the unit for full platform motion and never attempt to adjust settings during operation.
Why: Prevents injury from moving parts and protects the drive mechanism from damage during parameter changes.
Allow the motor to reach thermal equilibrium before critical experiments by running for 10-15 minutes at operating speed.
Why: Eliminates temperature-related speed variations that can occur during initial operation startup.
Document baseline vibration levels when properly balanced to establish reference conditions for troubleshooting.
Why: Provides objective criteria for identifying mechanical issues before they affect experimental results.

Background reading relevant to this product:
What is the maximum sample capacity for the 800×600mm platform?
The platform dimensions accommodate various container arrangements depending on vessel size. For standard microplates, multiple 96-well plates can be processed simultaneously. For larger flasks or bottles, consult the platform loading guide to ensure proper weight distribution and secure positioning.
How does the PID controller maintain speed accuracy across different load conditions?
The PID controller continuously monitors motor speed and compensates for variations caused by sample weight, viscosity, or platform loading. This closed-loop system maintains ±1 rpm accuracy regardless of reasonable load variations within the specified operating range.
Can the amplitude be adjusted during operation or only when stopped?
Amplitude adjustments should be made when the unit is stopped to prevent mechanical stress on the drive system. The range extends up to 50mm diameter, allowing optimization for different mixing requirements before starting each protocol.
What maintenance procedures are required for consistent performance?
Routine maintenance includes periodic cleaning of the platform surface, inspection of mounting hardware for tightness, and annual calibration verification. The multidimensional drive system requires minimal lubrication following manufacturer specifications.
Is the timer function suitable for overnight or weekend protocols?
Yes, the programmable timer supports operation up to 9999 hours with automatic shutdown capabilities. This enables extended incubation protocols common in cell culture and extraction applications while maintaining consistent agitation parameters.
How does this compare to linear shakers for cell culture applications?
Rotatory shaking provides gentler agitation suitable for shear-sensitive cells while maintaining effective mixing. The orbital motion pattern reduces mechanical stress compared to linear shakers, making it preferable for suspension cultures requiring extended agitation periods.
What safety features prevent damage from unbalanced loads?
The multidimensional drive system includes overload protection and vibration monitoring. If excessive imbalance is detected, the system will reduce speed or stop operation to prevent mechanical damage and ensure operator safety.
Can the unit operate in temperature-controlled environments?
The shaker is designed for standard laboratory conditions. For temperature-sensitive applications, the unit can be placed in environmental chambers or incubators that accommodate its dimensions and provide adequate clearance for platform motion.
