High-Performance Rotary Shakers: Precision Agitation for Modern Laboratories

In biological research, chemical analysis, and industrial testing, the Rotary Shaker is an essential instrument for achieving consistent, circular motion. Designed to provide optimal aeration for cell cultures and uniform mixing for chemical reagents, our rotary shakers ensure a smooth, horizontal plane of motion that eliminates “dead zones” in your samples.

We offer three specialized configurations—Basic, Advance, and Pro—to provide the perfect balance of capacity, digital control, and environmental integration for your facility.

Detailed Model Breakdown

1. Basic Model: Reliable Daily Utility

The Basic Model is a robust, entry-level solution for standard laboratory shaking requirements where consistent speed and mechanical simplicity are the primary goals.

• Heavy-Duty Build: Features a powder-coated steel housing and a non-slip rubber platform suitable for standard flask attachments.

• Simple Interface: Equipped with an analog speed knob and a mechanical timer (up to 120 minutes) or a “continuous run” mode.

• Quiet Operation: Utilizes a balanced drive mechanism to minimize noise and benchtop vibration during long-run cycles.

2. Advance Model: The Research Standard

The Advance Model is designed for scaling up biological processes, offering precision microprocessor control and enhanced safety features for valuable samples.

• Triple-Eccentric Drive: Employs a sophisticated drive system that handles unbalanced loads with ease, ensuring the platform remains level even at high RPMs.

• Microprocessor PID Control: Maintains set speed within $\pm 1$ RPM, automatically compensating for changes in load or voltage fluctuations.

• Safety Alarms: Includes audible and visual alarms for speed deviations and an automatic shut-off feature if the platform is obstructed or the motor overheats.

3. Pro Model: The Intelligent Shaking System

Our Pro Model is the ultimate solution for high-throughput screening and automated pilot plants, offering total environmental integration and data traceability.

• Programmable Multi-Step Cycles: Allows users to program complex shaking profiles, including ramping speeds and timed pauses, via a high-resolution touchscreen.

• Direct Drive Technology: A maintenance-free brushless DC motor provides high torque at low speeds, ideal for large-volume carboys or heavy stainless steel trays.

• Environmental Connectivity: Designed to operate inside CO2 incubators or cold rooms (up to 40°C and 80% humidity) with remote control capabilities via RS485/USB.

• Smart Recovery: Features an “Automatic Restart” function that saves progress during power interruptions and returns to the exact set point once power is restored.

Key Features & Platform Versatility

• Universal Attachments: Platforms can be customized with universal spring-wire racks for mixed glassware, dedicated flask clamps ($50\text{ml}$ to $6000\text{ml}$), or flat rubber mats.

• Vibration Isolation: High-grade internal shock absorbers prevent kinetic energy from transferring to the laboratory bench, protecting sensitive nearby equipment.

• Soft-Start Technology: Gradually accelerates the platform to the set speed to prevent sudden splashing or mechanical stress on the drive system.

• Maintenance-Free Bearings: Permanently lubricated ball bearings ensure thousands of hours of service without the need for manual greasing.
