4-5R Refrigerated High-speed Centrifuge 750ml x 4 Rotor for Labs

The 4-5R Refrigerated Centrifuge is a high-capacity, desktop low-speed refrigerated centrifuge engineered for high-throughput laboratories. It supports sample volumes from 0.2 ml to 750 ml, making it ideal for clinical, CDC, blood bank, urine, saliva, biochemical, radioimmunology, and pharmaceutical applications.

Driven by an AC frequency conversion motor, the 4-5R features a microprocessor-controlled electrical system with an HD touch panel for intuitive operation. Its T45 steel one-piece stamped body, electronic door lock, and comprehensive safety protections ensure reliable daily performance in demanding laboratory environments.

• Robust Build & Safety: T45 steel one-piece stamping body, accidental power-off door protection, and 3-grade rubber damping automatic balance.
• Smart & Efficient: Rotor auto-ID with alarm, 99 programmable presets, and one-key recall for rapid workflow setup.
• Eco-Friendly Cooling: Environmentally friendly refrigerant with intelligent temperature control and scene-switching capability.
• User-Friendly HD Touch: Smooth touchscreen operation with multiple centrifugal functions including timed, gradient, spot movement, and timing centrifugation.
• 10-Gear Acceleration/Brake: Soft start/stop technology prevents secondary mixing of samples.
• Aerodynamic Design: Circular hanging basket reduces wind resistance and saves energy.
• Corrosion-Resistant: Teflon-coated horizontal bracket for long-term durability.
• Versatile Rotor & Adapters: Compatible with blood vessels, centrifuge tubes, microplates, and cell culture bottles.

The instrument's electronic door lock prevents operation unless the door is properly closed and locked. During operation, the door cannot be opened; it unlocks automatically only when the rotor reaches zero speed, ensuring operator safety at all times.

An optimized shock absorption system delivers smooth, low-vibration, low-noise operation with excellent separation results. Additional safety protections include:

• Steel plate protection surrounding the centrifugation chamber
• Automatic shutdown in case of unbalance, over-temperature, or over-speed
• Automatic slowdown and stop protection when maximum speed reaches 500 r/min
• Automatic storage of all run parameters for direct recall on next power-up
• Multiple rotor options for multi-purpose use from a single machine
