Introduction
The unit accepts a wide range of angle and swing rotors and can be fitted with custom adapters to accommodate tubes from 0.1 ml to 500 ml, enabling multi‑purpose use. The integrated refrigeration system allows accurate temperature regulation during runs to protect temperature‑sensitive samples and improve separation efficiency.

Features

• Full metal construction with multi‑layer explosion protection for operator safety and long service life.
• High‑strength aluminum alloy rotors, compatible with high‑temperature and high‑pressure disinfection.
• Embedded microprocessor control with brushless DC motor drive: maintenance‑free, good shock absorption and stable operation.
• 5‑inch LCD screen displaying parameters in real time; intuitive and simple user interface.
• Electromechanical integrated door lock for secure operation.
• Integral food‑grade silicone sealing ring to prevent aerosol leakage and ensure operator safety.
• CFC‑free compressor unit with environmentally friendly refrigerant R404a; adjustable temperature range during operation: -20℃ to +40℃; rapid cooling and standby cooling to maintain set temperature.
• Self‑test and alarm functions for blockage, overspeed, overtemperature and other fault conditions; excellent vibration damping.
• Multiple user‑defined program groups; easy access to common programs and boot recall of the last program.
• Optional automatic rotor recognition.
