3. **Maximum Relative Centrifugal Force (RCF)**: The highest RCF that the rotor can achieve, suitable for separating even dense samples.
4. **Maximum Capacity**: Indicates the largest volume of samples that can be processed at one time.
5. **Temperature Control Range**: Operates efficiently between -20°C to 40°C, making it ideal for various sample types.
6. **Temperature Control Accuracy**: ±1°C, providing stable and reliable cooling during operation.
7. **Timing Range**: Allows for precise control with a range from 0 to 99 hours, 59 minutes, and 59 seconds.
8. **Display Mode**: Equipped with an LCD screen for easy monitoring and adjustment of parameters.
9. **Motor**: Utilizes an AC variable frequency motor for smooth and energy-efficient performance.
10. **Drive Shaft**: Features a sealed, pre-lubricated drive shaft for long-lasting durability and minimal maintenance.
11. **Refrigeration System**: As previously mentioned, includes a fully enclosed, air-cooled Copeland compressor with fluorine-free refrigerant.
12. **Door Lock**: Incorporates an electronic door lock for enhanced safety and convenience.
13. **Shock Absorption**: Equipped with a three-stage shock absorption system to reduce vibration and improve stability.
14. **Maximum Noise Level**: Operates quietly at up to 60 dB, ensuring a comfortable working environment.
15. **Power Requirements**: Supports standard voltage, frequency, power, and maximum current specifications.
16. **Liner Material**: Constructed with stainless steel for corrosion resistance and ease of cleaning.
17. **Cabinet Material**: Made from high-quality steel plate for durability and structural integrity.
18. **Main Current Protection**: Automatically cuts off power if the current exceeds the rated value, preventing damage.
19. **Over-Temperature Protection**: Stops the motor if the temperature rises beyond the set point by ±6°C.
20. **Overspeed Protection**: Activates when the speed goes beyond the preset limit by ±300 rpm.
21. **Unbalance Protection**: Detects excessive vibration caused by unbalanced loads and stops the motor to prevent damage.
22. **Door Safety Protection**: Prevents startup if the door is not properly closed, and automatically stops the motor if the door is opened during operation.
This advanced centrifuge is ideal for laboratories requiring precision, reliability, and safety in their sample processing. Its comprehensive protection systems ensure both equipment longevity and user safety. For more information, visit [http://news.chinawj.com.cn](http://news.chinawj.com.cn).

Electric Gate Valve
An electric Gate Valve is a type of valve that uses an Electric Actuator to open and close the gate of the valve. The gate is a flat or wedge-shaped piece that moves perpendicular to the flow of the fluid. When the valve is open, the gate is lifted or pushed aside to allow the fluid to pass through. When the valve is closed, the gate is lowered or pressed against the valve seat to prevent the fluid from flowing.
Electric gate valves are commonly used in industrial applications where precise control of the fluid flow is required. They are often used in pipelines, water treatment plants, oil and gas refineries, and chemical processing plants. The electric actuator allows for remote control of the valve, which can be operated from a control room or a computerized system. This makes it easier to monitor and adjust the flow of the fluid, which can improve efficiency and reduce the risk of leaks or spills.
