OS-7200 Shaker (Orbital, 2.0in)

OS-7200 Orbital Shaker (2.0-inch Orbit)

The OS-7200 is a heavy-duty orbital shaker engineered for high-capacity laboratory applications that require a larger displacement and exceptional stability. Featuring a massive 50.8mm (2.0-inch) orbital diameter, it is specifically designed to provide superior aeration and mixing for large-volume vessels, such as 4L and 6L Erlenmeyer flasks.

High-Performance Engineering

The OS-7200 combines robust mechanical design with digital precision to handle the most demanding workloads:

• Powerful Brushless DC Motor: The direct drive (DD) system utilizes a maintenance-free brushless motor. Combined with a triple cam assembly, it ensures quiet operation and uniform rotation even under maximum weight loads.
• Microprocessor PID Control: Provides ultra-precise speed regulation and reproducible shaking results, ensuring your experiments remain consistent day after day.
• Intelligent Speed Calibration: A built-in calibration procedure ensures that the RPM displayed on the interface matches the actual mechanical speed, critical for validated environments.
• Wide Speed Range: Capable of speeds from 30 to 300 RPM (up to 500 RPM for specific configurations), providing the flexibility needed for everything from gentle washing to vigorous aeration.

Advanced Operational Features

• Best Effort Run: This safety logic automatically detects if the shaker is struggling due to an unbalanced load or excessive weight. Instead of halting, it adjusts the speed to the maximum safe RPM to ensure your experiment continues.
• Gentle Start/Stop: Programmed acceleration and deceleration ramps prevent sudden jolts, protecting your samples from splashing or flask displacement.
• Positioned Stop: The platform always returns to the same starting coordinates upon completion. This is a vital feature for labs using automated liquid handling or sampling robotics.
• Low-Profile Stability: The heavy-cast body and low center of gravity minimize vibration, preventing the unit from "walking" across the benchtop during high-speed runs.

User Convenience & Connectivity

• VFD Display & Intuitive Interface: Features a bright Vacuum Fluorescent Display (VFD) that is easily visible from across the lab. Controls include a responsive dial and durable membrane touch switches.
• Comprehensive Timer: Set-and-forget operation from 1 minute up to 1,000 hours, or choose continuous mode for long-term cell culture.
• Data Integration: Built-in RS-232 and USB ports allow for easy logging and remote PC control.
• LC Connected (Optional): Pair with the LC GreenBox to monitor and control your shaker remotely via smartphone or tablet, providing peace of mind during overnight runs.

Safety Measures

• Automatic Restart: In the event of a power outage, the unit resumes operation automatically using the last saved settings.
• Triple Protection: Includes a speed deviation alarm, over-current protection, and a motor-stall sensor to protect both the equipment and your samples.
