The refrigeration system features a fully enclosed, air-cooled Copeland compressor unit using fluorine-free refrigerant. This high-speed, large-capacity refrigerated centrifuge is designed for precision and efficiency in laboratory environments. Below are the detailed technical specifications:
1. **Maximum Speed**: Refers to the highest rotational speed achieved by the rotor and stator.
2. **Speed Accuracy**: ±30 rpm, ensuring consistent performance during operation.
3. **Maximum Relative Centrifugal Force (RCF)**: Represents the maximum force that can be applied by the rotor.
4. **Maximum Capacity**: Indicates the largest volume or weight that the centrifuge can handle at one time.
5. **Temperature Control Range**: Operates within a wide range of -20°C to 40°C, suitable for various sample types.
6. **Temperature Control Accuracy**: Maintains precise temperature control with an accuracy of ±1°C.
7. **Timing Range**: Offers flexible timing options from 0 to 99 hours, 59 minutes, and 59 seconds.
8. **Display Mode**: Equipped with an easy-to-read LCD screen for real-time monitoring.
9. **Motor Type**: Uses an AC variable frequency motor for smooth and energy-efficient operation.
10. **Drive Shaft**: Features a sealed, pre-lubricated drive shaft to ensure long-lasting performance.
11. **Refrigeration System**: As previously mentioned, it includes a fully enclosed, air-cooled Copeland compressor with environmentally friendly refrigerant.
12. **Door Lock**: Utilizes an electronic door lock for enhanced security and safety.
13. **Shock Absorption**: Incorporates a three-stage shock absorption system to minimize vibration and protect sensitive samples.
14. **Maximum Noise Level**: Operates quietly at no more than 60 dB, ensuring a comfortable working environment.
15. **Power Requirements**: Includes voltage, frequency, power rating, and maximum current specifications.
16. **Liner Material**: Constructed from stainless steel for durability and ease of cleaning.
17. **Cabinet Material**: Made from high-quality steel plate for strength and stability.
18. **Main Current Protection**: Automatically shuts down the unit if the power supply exceeds the rated current.
19. **Over-Temperature Protection**: Stops the motor if the internal temperature rises above the set point by 6°C.
20. **Overspeed Protection**: Prevents damage by stopping the motor if the speed goes beyond the preset limit by 300 rpm.
21. **Unbalance Protection**: Detects excessive vibration due to unbalanced loading and halts the operation.
22. **Door Safety Protection**: Ensures the centrifuge cannot start if the door is not properly closed, and automatically stops if the door is opened during operation.
This advanced refrigerated centrifuge is ideal for laboratories requiring accurate and reliable separation of biological and chemical samples under controlled conditions. Its comprehensive safety features and user-friendly design make it a top choice for researchers and professionals alike.

Ball Valve
Ball valve is evolved from the plug valve, its opening and closing parts as a ball, using the ball to rotate 90 degrees around the axis of the stem to achieve the purpose of opening and closing, the difference is that the cock body is a ball, with a circular through hole or channel through its axis. The ratio of the sphere to the passageway should be such that when the ball is rotated 90 degrees, the inlet and outlet should be completely spherical, thus cutting off the flow.
The role of ball valve in the pipeline is mainly used to cut off, distribute and change the direction of media flow, designed into the V-shaped opening ball valve also has good flow regulation function.
Ball valve is not only simple in structure, good sealing performance, but also in a certain nominal range of small volume, light weight, less material consumption, small installation size, and driving torque is small, easy to operate, easy to realize rapid opening and closing, is one of the fastest developing valve varieties in recent decades. Especially in the United States, Japan, Germany, France, Italy, West, Britain and other industrial developed countries, ball valves are widely used, the variety and number of use is still continuing to expand, and to high temperature, high pressure, large mouth, high sealing, long life, excellent regulatory performance and a valve multifunctional direction, its reliability and other performance indicators have reached a higher level, And has partially replaced Gate Valve, Globe Valve, Regulating Valve.
