OS-4000 Shaker (Dual Action) (Orbital), 450×450mm Platform

OS-4000 Shaker (Dual Action): High-Performance Orbital & Reciprocating Shaking

The OS-4000 is a robust, large-capacity laboratory shaker designed for versatility and precision. Featuring a generous 450×450mm platform, it is engineered to handle heavy workloads while maintaining a smooth, quiet operation. Whether you are working on cell cultures, solubility studies, or general mixing, the dual-action motion (Orbital or Reciprocating) provides the flexibility needed for diverse laboratory applications.

Key Performance Features

• Dual-Action Versatility: Easily switch between orbital and reciprocating motions to accommodate different sample types and mixing requirements.
• Precision Control: Driven by a microprocessor PID controller, the unit offers a wide speed range up to 500 rpm. The maintenance-free Brushless DC (BLDC) motor ensures consistent, powerful motion without the noise or vibration of traditional motors.
• Intelligent Load Management: The "Best Effort Run" function automatically adjusts RPM if the workload exceeds capacity, ensuring your run continues safely without sudden stops.
• Variable Amplitudes: Standard 19.1mm (0.75”) or optional 25.4mm (1”) stroke lengths are available to optimize oxygen transfer or mixing intensity.

Designed for Convenience

• User-Friendly Interface: Features Lab Companion’s signature bright VFD display and a durable membrane touch control panel that is easy to clean and operate even with gloves.
• Automated Positioning: The platform always stops at its original starting point. This is a critical feature for laboratories using automated dosing, sampling systems, or liquid handling robots.
• Digital Connectivity: Equipped with RS-232 and USB ports for comprehensive data logging and external control.
• Remote Monitoring: With the optional LC GreenBox, you can monitor your shaking parameters in real-time via a mobile app, giving you peace of mind when away from the lab.

Safety First

• Automatic Restart: In the event of a power interruption, the shaker automatically resumes operation to protect your samples.
• Integrated Alarms: Visual and audible alarms for speed deviations, over-current protection, and stalled platform detection.
• Low-Profile Stability: The heavy-duty design minimizes "walking" or sliding across the benchtop, even at maximum speeds.
