The ConductScience Wrist Shaker is a precision orbital shaking platform designed for consistent sample agitation in laboratory applications. This benchtop instrument features dual-arm 304 stainless steel construction with variable frequency motor control, providing reliable orbital motion at 12° angle with speeds ranging from 50-600 rpm. The system accommodates up to 12 standard flasks simultaneously with a maximum loading capacity of 6.8 kg per side.
The unit operates in both continuous and timed modes, making it suitable for extended protocols requiring consistent agitation over defined periods. With its robust construction and precise speed control, the instrument supports various mixing and extraction applications where reproducible sample movement is critical for experimental consistency.
How It Works
The wrist shaker operates on orbital motion principles, where samples undergo simultaneous horizontal circular movement at a fixed 12° angle. The variable frequency motor drives dual arms in synchronized motion, creating consistent agitation patterns across all mounted vessels. This orbital movement generates continuous mixing through gravitational and centrifugal forces as samples move in elliptical paths within their containers.
The 12° angle optimization provides efficient mixing while minimizing sample splashing and vessel stress. The stainless steel construction ensures chemical compatibility and thermal stability across the specified temperature range of 4°C to 40°C, while the variable speed control allows protocol optimization for different sample viscosities and mixing requirements.

| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Loading Capacity | 6.8 kg per arm side (13.6 kg total) | Entry-level models often offer 2-4 kg total capacity | Higher capacity enables simultaneous processing of more samples or larger vessels, improving laboratory throughput. |
| Speed Range | 50-600 rpm with variable frequency motor | Basic models may have limited speed ranges or fixed increments | Wide speed range allows optimization for different sample viscosities and mixing requirements across diverse protocols. |
| Construction Material | 304 stainless steel main body and arms | Budget models often use painted steel or aluminum | Stainless steel provides superior chemical resistance and durability for harsh solvent environments and extended use. |
| Operation Modes | Continuous or timing operation | Many models offer only continuous operation | Timing mode enables precise protocol control without constant monitoring, improving experimental reproducibility. |
| Clip Capacity | 12 flask clips with 50mm maximum opening | Smaller units often accommodate 6-8 vessels | Higher vessel capacity and larger opening size accommodate more samples and diverse glassware types in single runs. |
| Power Consumption | 60W consumption | Varies by model depending on motor design | Efficient power usage minimizes heat generation while providing consistent performance for temperature-sensitive applications. |
The ConductScience Wrist Shaker offers high loading capacity, comprehensive speed control, and durable stainless steel construction. The combination of dual timing modes and 12-vessel capacity provides versatility for diverse laboratory mixing applications.
Practical Tips
Verify actual speed using a non-contact tachometer periodically, especially after extended use or transport.
Why: Speed accuracy is critical for reproducible extraction protocols and consistent experimental results.
Clean stainless steel surfaces with isopropanol after use with organic solvents to prevent residue buildup.
Why: Regular cleaning maintains chemical compatibility and prevents cross-contamination between different sample types.
Load vessels symmetrically across both arms and secure all clips before operation to minimize vibration.
Why: Balanced loading ensures smooth operation, reduces wear on motor components, and prevents vessel displacement during extended runs.
Always verify clip security and vessel compatibility before starting, especially with new glassware types.
Why: Proper clip engagement prevents vessel ejection during operation, protecting both samples and laboratory personnel.
Document speed settings, timing, and ambient temperature for each protocol to ensure reproducibility.
Why: Environmental conditions and agitation parameters directly affect extraction efficiency and experimental outcomes.
If excessive vibration occurs, check for unbalanced loading and ensure the unit is on a level, stable surface.
Why: Vibration indicates mechanical stress that can affect mixing consistency and potentially damage internal components.
Allow samples to reach thermal equilibrium with ambient temperature before starting agitation protocols.
Why: Temperature differences can create convection currents that interfere with consistent orbital mixing patterns.
Inspect flask clips monthly for wear or damage, particularly the gripping surfaces that contact vessel necks.
Why: Worn clips may not securely hold vessels during operation, creating safety hazards and potential sample loss.

Background reading relevant to this product:
What is the maximum vessel size that can be accommodated on this shaker?
The flask clips accommodate vessels with neck openings up to 50mm diameter, which covers standard Erlenmeyer flasks, beakers, and most laboratory glassware. Maximum loading is 6.8 kg per arm side.
Can the unit operate continuously for extended extraction protocols?
Yes, the shaker features both continuous and timing operation modes. The variable frequency motor and robust construction support extended continuous operation within the specified environmental conditions.
How precise is the speed control for reproducible protocols?
The variable frequency motor provides speed control across 50-600 rpm range. For specific speed accuracy and stability specifications, consult the product datasheet.
What maintenance is required for consistent performance?
Regular maintenance includes cleaning the stainless steel surfaces with appropriate solvents, checking clip tightness, and periodic inspection of motor operation. The stainless steel construction minimizes corrosion-related maintenance.
Is the unit suitable for temperature-sensitive samples?
The 60W power consumption generates minimal heat, and operation is specified for 4°C to 40°C ambient conditions. However, for precise temperature control, external temperature monitoring is recommended.
How does this compare to magnetic stirring for mixing applications?
Orbital shaking provides gentler agitation than magnetic stirring, especially for larger volumes and solid-liquid extractions where magnetic bar effectiveness decreases. The orbital motion ensures complete sample circulation.
Can both arms be loaded independently with different sample types?
Yes, each arm can accommodate different vessel types and sample volumes up to the 6.8 kg per side limit, though balanced loading is recommended for optimal operation.
What power supply variations are acceptable?
The unit accepts AC 110V or 220V ±10% at 50/60Hz, providing flexibility for international laboratory installations with appropriate power cord configuration.
