This article will comprehensively introduce the technical characteristics, application fields, and comparison with other centrifuges of the 21S high-speed cryogenic centrifuge, helping users make the best choice.
Maintenance free design: The 21S high-speed freeze centrifuge adopts a brushless high torque variable frequency motor, which means that the equipment requires almost no maintenance during use, eliminating the trouble of regularly replacing carbon brushes and reducing the cost of equipment use.
No dust pollution: Due to the use of brushless motors, the equipment will not produce carbon powder during operation, ensuring a clean experimental environment, especially suitable for experiments with high requirements for laboratory environment.
Fast lifting speed: This motor provides higher power, allowing the equipment to quickly reach the set speed, reducing the waiting time for experiments and improving experimental efficiency.
Accurate speed control: The flexible shaft drive system of the 21S high-speed freeze centrifuge can directly drive the rotor, ensuring more precise speed control.
Smooth operation: The flexible shaft drive system not only reduces the burden on the motor, but also effectively reduces vibration and noise during equipment operation, ensuring a smooth and undisturbed centrifugal process, suitable for high-precision experimental requirements.
Protecting the motor: This system effectively protects the motor, reduces mechanical losses, and extends the service life of the equipment.
Easy to operate: The 21S high-speed freezing centrifuge is equipped with a 5-inch high-definition LCD touch screen, providing users with an intuitive operation interface, clear interface, and convenient function operation.
Real time display: Through the LCD screen, parameters such as speed, time, temperature, and rise and fall rate can be displayed simultaneously, and the operation of the equipment can be monitored in real time to ensure the accuracy of experimental data.
Human Computer Interaction Design: A user-friendly interface allows operators to quickly master device usage without the need for tedious training.
Environmentally friendly refrigeration: 21S adopts imported fluorine free compressor units, which not only improves refrigeration efficiency, but also meets modern environmental standards, avoiding the pollution of traditional fluorine refrigerants to the environment.
Dual circulation pipeline design: The unique dual circulation pipeline and dual electronic valve temperature control system can achieve more precise temperature control, ensuring smaller temperature changes and reducing temperature fluctuations during sample processing.
Rapid cooling: The device can reduce the temperature from room temperature to 4 ℃ within 5 minutes, ensuring the stability of temperature sensitive samples and suitable for efficient separation operations.
Automatic induction electric door lock: To ensure the safety of operators, the 21S is equipped with an automatic induction electric door lock, which automatically locks the door during equipment operation to prevent experimenters from opening the door cover during operation.
Emergency unlocking function: In emergency situations, the device is equipped with an emergency unlocking function to ensure that users can quickly open the device and take out samples.
Overspeed, overtemperature, and imbalance protection: The equipment has automatic protection functions for overspeed, overtemperature, and imbalance. Once overspeed or other abnormalities occur, the system will automatically stop running to ensure experimental safety.
High quality steel structure: The equipment body is made of high-quality steel structure, equipped with a precision steel explosion-proof protective inner sleeve, and multiple internal and external protection designs to ensure that the equipment will not be damaged abnormally during high-speed centrifugation.
Stainless steel centrifugal chamber: The use of stainless steel centrifugal chamber improves the corrosion resistance and damage resistance of the equipment, and adapts to various high-strength experimental requirements.
Three level vibration reduction system: This equipment is equipped with a three-level vibration reduction system, which effectively reduces the impact of vibration during the centrifugation process on the equipment and ensures the optimal centrifugal effect.
