The L20R Desktop High-Speed Refrigerated Centrifuge is a high-efficiency centrifuge developed by Changsha Shi Ge Yan Biotechnology Co., Ltd., specifically designed to meet the demands of high-speed, high-precision experiments, delivering reliable and stable performance.
This article provides a detailed overview of the L20R Desktop High-Speed Refrigerated Centrifuge, including its technical features, technical parameters, compatible rotors, application fields, and other key aspects. It aims to help users gain a comprehensive understanding of the equipment and highlight the after-sales service commitment of Changsha Shi Ge Yan Biotechnology Co., Ltd.: a three-year warranty with replacement instead of repair.
Maintenance-Free Design: The L20R Desktop High-Speed Refrigerated Centrifuge adopts a brushless inverter motor. The brushless design eliminates the need for regular maintenance required by traditional motors, such as carbon brush replacement. There is no need to worry about carbon powder contamination, which improves the cleanliness of the laboratory environment.
High Torque and Low Noise: This motor provides high torque, enabling it to reach the set high speed in a short time to ensure efficient centrifugation. Meanwhile, the low-noise design creates a quiet working environment for experiments, making it suitable for long-term use.
Fast Acceleration and Deceleration: The inverter motor not only enhances the operating efficiency of the equipment but also supports fast acceleration and deceleration, significantly saving experiment time.
Digital Display and Real-Time Adjustment: The L20R Desktop High-Speed Refrigerated Centrifuge is equipped with a microprocessor control system, which displays key parameters such as speed, time, and temperature via digital display. Users can adjust parameters in real time to achieve optimal experimental results.
Operating Parameter Switching and RCF Value Display: The equipment offers RCF value display, allowing real-time monitoring of centrifugal force. This helps researchers precisely control experimental conditions.
Automatic Memory and Quick Program Calling: The equipment can automatically memorize the last set of operating programs and store and call up to 10 programs. Additionally, the panel is equipped with four quick program keys, making the operation of frequently used programs more convenient.
Imported Fluorine-Free Compressor Unit: The L20R is equipped with an imported fluorine-free compressor unit and uses R404A refrigerant, ensuring that the refrigeration process contains no harmful substances and complies with environmental protection requirements.
Fast Refrigeration Function: After reaching the maximum speed, the equipment can maintain the sample temperature at 4°C or below. Even at high speeds, samples remain at a low temperature, making it suitable for processing temperature-sensitive samples.
Precise Temperature Control: The equipment achieves a temperature control accuracy of ±1°C. It effectively controls the temperature of the centrifugal chamber through a condensation pipeline system and a dual-circulation refrigeration pipeline, ensuring temperature stability during centrifugation.
Automatic Electric Induction Door Lock: The equipment is equipped with an automatic electric induction door lock function. It ensures that the door lock closes automatically during operation, preventing safety hazards caused by incorrect operation.
Emergency Unlocking Function: In case of abnormal operation of the equipment, users can quickly take out samples through the emergency unlocking function, ensuring operational safety.
Automatic Protection Against Over-Speed, Over-Temperature, and Imbalance: The equipment has a built-in multiple safety protection system. In the event of over-speed, over-temperature, or imbalance, the equipment will automatically shut down and display an error code to prevent damage to the equipment or samples.
Independent Motor-Serviced Door Cover: The L20R is equipped with an independent motor-serviced door cover, which greatly reduces the labor intensity of operators.
High-Quality Body and Inner Sleeve Design: The equipment body adopts a high-quality steel structure, with a built-in fine steel explosion-proof protective inner sleeve and a 304 stainless steel centrifugal chamber. This triple protection enhances the stability and safety of the equipment.
Spring Cone Sleeve for Rotor Connection: A spring cone sleeve is used to connect the rotor to the main shaft. The rotor can be installed and disassembled very conveniently, and the non-directional design makes the operation simpler and more efficient.
Three-Level Shock Absorption System: The L20R Desktop High-Speed Refrigerated Centrifuge is equipped with a three-level shock absorption system, which effectively reduces vibration during high-speed operation, improves the stability of the equipment, and ensures the accuracy of sample separation results.
The L20R Desktop High-Speed Refrigerated Centrifuge supports a variety of rotor configurations to meet different capacity and centrifugal force requirements. The following are common compatible rotors and their parameters:
