The Table Top Capacity Shaker provides reliable rotatory agitation for laboratory applications requiring gentle to moderate mixing. This benchtop instrument features a brushless DC motor delivering orbital shaking motion with 10mm amplitude across a speed range of 50-500 rpm with ±1 rpm accuracy. The 320×320mm platform accommodates standard laboratory vessels including petri dishes, culture plates, and flasks up to 7.5kg total load capacity.
The LED display provides clear visualization of speed and timing parameters, with programmable timing from 1 minute to 99 hours 99 minutes. The universal power supply (AC 100-240V, 50/60Hz) ensures global laboratory compatibility, while the compact footprint (365×355×142mm) fits standard benchtop configurations. Standard configuration includes a universal petri dish rack set with rubber pads and fixing ropes for secure vessel positioning during operation.
How It Works
The Table Top Capacity Shaker operates through orbital motion generated by a brushless DC motor system that converts rotational motion into a horizontal circular pattern. The platform moves in a fixed 10mm diameter orbit at user-selected speeds between 50-500 rpm, creating gentle mixing action that promotes fluid circulation without the high shear forces associated with magnetic stirring or vortex mixing.
The brushless motor design provides consistent torque delivery and eliminates maintenance associated with brush wear while ensuring quiet operation. The orbital motion pattern creates a rolling wave action in liquid samples, promoting efficient gas exchange at the liquid-air interface and uniform distribution of nutrients or reagents throughout the sample volume. The rubber pad system and fixing ropes secure vessels against the centrifugal forces generated during operation, preventing sample spillage while maintaining consistent positioning.

| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Speed Range | 50-500 rpm | Entry-level models often offer narrower speed ranges or lower maximum speeds | Wide speed range accommodates both gentle cell culture applications and more vigorous extraction procedures in a single instrument. |
| Speed Accuracy | ±1 rpm | Basic models may have ±5-10 rpm accuracy | Precise speed control ensures reproducible results in applications sensitive to agitation variations. |
| Load Capacity | 7.5kg including fixtures | Smaller units often support 2-5kg maximum load | Higher capacity enables simultaneous processing of multiple samples or larger volume containers for improved throughput. |
| Platform Size | 320×320mm | Compact models typically offer 250×250mm or smaller platforms | Larger platform accommodates more vessels or larger containers for versatile experimental designs. |
| Timer Range | 1min to 99h99min | Basic models may limit timing to 24 hours or less | Extended timing capability supports multi-day protocols without requiring operator intervention or timer resets. |
| Motor Type | Brushless DC motor | Budget models often use brushed motors | Brushless design provides longer operational life and more consistent performance with reduced maintenance requirements. |
This orbital shaker offers a combination of precise speed control, substantial load capacity, and extended timing capability in a compact benchtop format. The brushless motor system and wide speed range make it suitable for diverse applications from gentle cell culture to vigorous extraction procedures.
Practical Tips
Start new protocols at lower speeds (50-100 rpm) and gradually increase to determine optimal agitation conditions for your specific application.
Why: Prevents sample damage and allows optimization of mixing conditions for reproducible results.
Clean the platform and rubber pads after each use with appropriate laboratory disinfectants to prevent cross-contamination.
Why: Maintains sterile conditions for cell culture work and prevents buildup of residues that could affect platform balance.
Always secure vessels with fixing ropes and verify total load is under 7.5kg before starting operation.
Why: Prevents vessel displacement during operation which could cause spillage or damage to samples and equipment.
Verify speed accuracy periodically using a calibrated tachometer, especially for protocols requiring precise agitation conditions.
Why: Ensures continued accuracy of speed control which is critical for reproducible experimental results.
Record speed and timing parameters in laboratory notebooks for each experiment to enable protocol replication.
Why: Documents agitation conditions as experimental variables that can affect results and enable troubleshooting if needed.
If excessive vibration occurs, check that vessels are properly secured and total load is evenly distributed across the platform.
Why: Unbalanced loads can cause vibration that affects mixing efficiency and may damage the motor system over time.
Allow the motor to warm up for 2-3 minutes at low speed before starting high-speed operations for optimal performance.
Why: Enables motor components to reach operating temperature for consistent performance and extends equipment lifespan.
Inspect fixing ropes regularly for wear and replace when elasticity decreases to maintain secure vessel mounting.
Why: Worn ropes may not provide adequate securing force, increasing risk of vessel movement and sample spillage during operation.

Background reading relevant to this product:
What is the maximum vessel size that can be accommodated on the 320×320mm platform?
The platform can accommodate vessels up to 320mm in any dimension, with total load capacity including fixtures limited to 7.5kg. Common configurations include multiple 150mm petri dishes, standard tissue culture plates, or larger flasks depending on the specific rack configuration used.
How does the speed accuracy of ±1 rpm affect reproducibility in cell culture applications?
The ±1 rpm accuracy ensures consistent shear conditions between experiments, which is critical for cell culture applications where growth rates and morphology can be sensitive to agitation variations. This precision supports reproducible results in protocols requiring specific mixing conditions.
Can the timing function be used for overnight or multi-day protocols?
Yes, the timing range extends to 99 hours 99 minutes, supporting extended protocols including overnight cell culture maintenance, multi-day extraction procedures, or long-term dissolution studies without requiring operator intervention.
What maintenance is required for the brushless motor system?
Brushless motors require minimal maintenance compared to brushed alternatives. Regular cleaning of the platform and inspection of the drive mechanism are typically sufficient. Consult the user manual for specific maintenance intervals and lubrication requirements.
How does the 10mm amplitude compare to other orbital shakers for extraction efficiency?
The 10mm amplitude provides moderate agitation suitable for most laboratory applications. This amplitude offers efficient mixing for extraction procedures while remaining gentle enough for cell culture work, representing a balance between mixing efficiency and sample protection.
Can multiple different vessel types be used simultaneously on the platform?
The universal rack system with rubber pads can accommodate different vessel types simultaneously, provided the total weight does not exceed 7.5kg and vessels can be adequately secured with the fixing ropes to prevent movement during operation.
What data output or monitoring capabilities does the shaker provide?
The LED display shows current speed and timing parameters during operation. For data logging or remote monitoring capabilities, consult the product datasheet as these features vary by specific model configuration.
How does power consumption compare to magnetic stirrer alternatives?
At 30W power consumption, the orbital shaker uses more power than magnetic stirrers but provides superior mixing for larger volumes and multiple vessels simultaneously. The energy cost is offset by the ability to process multiple samples in parallel.
