1. Equipped with a 7-inch high-definition true-color touchscreen for easy operation and intuitive display; setting parameters and real-time operating parameters can be displayed on the same screen.
2. Ultra-large-capacity data storage and fault record functions can store thousands of historical records, making it convenient for users to track operational history data. Data can be exported via USB.
3. Users can customize the names and edit up to 100 stepwise centrifugation programs, each of which consists of 10 distinct centrifugation steps, thereby meeting diverse experimental needs.
4. Equipped with program mode, curve mode, and preset program call functions, as well as a three-level password control system to ensure safe and reliable instrument operation and facilitate fine-grained management. The system can record the rotational speed, temperature, and ramp-up/ramp-down curves from the previous run.
5. It features 10 acceleration curves and 11 deceleration curves, with adjustable acceleration and deceleration times to optimize the centrifugation effect as needed.
6. Equipped with rotor recognition functionality, it automatically identifies the installed rotor, preventing users from setting incorrect rotor number parameters.
7. Equipped with a suction-type door lock, the lid closes effortlessly and securely locks the centrifuge in place.
8. Equipped with a high-performance compressor from a renowned imported brand and using the fluorine-free refrigerant R134a, the machine can delay the shutdown of the compressor’s cooling function when in standby mode. Additionally, after the door is closed, the compressor’s cooling function can be delayed before being turned on, making it energy-efficient and environmentally friendly.
9. Equipped with multiple protection features, including door cover protection, overspeed protection, and imbalance protection, ensuring the instrument operates safely.
10. An optional RS232 serial port is available for easy collection of screen parameter information.
