circularorbitaldigital

Product Overview
The ZWY-304C benchtop CO2-resistant orbital shaker combines a magnetic direct-drive system with FOC vector control to provide stable, low-energy orbital shaking suitable for cell culture, microbiology and pharmaceutical labs operating under elevated CO2 and humidity conditions. Compact footprint and durable construction enable reliable operation in demanding incubator environments.

Key Features

• Magnetic Direct Drive System: High-torque magnetic driver with low power consumption (18 W), smooth motion, low noise, minimal vibration and very low heat generation for stable temperature control.
• Adjustable Shaking Orbit: 10-step orbit diameter adjustment (3–50 mm) to fit various vessel sizes; maximum load up to 7.5 kg.
• Dual Intelligent Control Modes:
  • Fixed-Value Mode: Quick setting of speed and time for straightforward operation.
  • Program Mode: Up to 9-step programmable sequences for complex protocols.
• High-Precision Speed Control: Speed range 20–350 rpm (no load) with accuracy up to ±1 rpm, ensuring uniformity and repeatability.
• Durable Construction: Built from high-performance materials for long-term use in harsh conditions (up to 37°C, CO2 20%, 95% RH).
• Handheld Intelligent Controller: Remote controller for operation without opening the incubator, with real-time parameter display.
• Safety & Protection:
  • Dual alarms for stall and overspeed.
  • Power-failure memory and auto-recovery to resume previous status after power restoration.
  • Parameter lock with password protection to prevent accidental changes.
  • Selectable motor rotation direction: forward and reverse.

Capacity & Applications
Designed for cell culture and microbiology workflows. Supports flasks, microplates and tube racks with multiple accessory platforms available for specific flask sizes and plates, making it suitable for biological research, pharmaceutical development and routine laboratory incubation with orbital shaking requirements.
