The Shanghai Yetuo low-speed multi tube rack automatic balancing centrifuge is a conventional sample separation equipment used in the laboratory. It is controlled by a microcomputer and driven by a DC brushless motor, integrating intelligent automatic balancing and multi tube rack batch processing core technology. It has the highest speed of 5500r/min, the highest relative centrifugal force of 4390 × g, and a speed accuracy of ± 10r/min. It can achieve solid-liquid, liquid-liquid, and mild separation, and effectively protect the activity of thermosensitive samples such as cells and proteins. The equipment is suitable for sample pretreatment needs in multiple fields such as biomedical, clinical laboratory, food testing, and chemical material research and development, and is the basic standard equipment for laboratory batch sample separation.

1、 Core technical parameters

1. Speed and centrifugal force: the highest speed is 5500r/min, the highest relative centrifugal force is 4390 × g, and it supports real-time conversion and setting of rpm/RCF

2. Processing capacity: Comes standard with multi specification tube racks, compatible with 5ml/7ml/15ml/50ml/100ml centrifuge tubes.

3. Time setting: 1min-99min.

4. Operating performance: The overall noise of the machine is ≤ 58dB (A), the amplitude is ≤ 0.1mm, and the acceleration/deceleration can be adjusted in multiple gears

5. Power supply: AC 220V 50Hz, power 450W, strong adaptability to wide voltage range

6. Body specifications: external dimensions 415mm × 560mm × 355mm, net weight 44kg, tabletop design saves space

2、 Core functional features

1. Intelligent automatic balancing: Equipped with a high-precision eccentricity detection system, it does not require manual calibration for balancing and can tolerate reasonable weight deviations. When the eccentricity exceeds the threshold, it automatically slows down and stops with sound and light alarms to prevent equipment resonance damage and sample leakage.

2. Batch processing of multi tube racks: Modular rotor design, supporting the adaptation of multi specification centrifuge tubes and microplates, capable of synchronously centrifuging dozens of samples at a time. The rack is equipped with sliding silicone gaskets to ensure that the centrifuge tubes are firmly fixed and the separation effect is uniform.

3. Jingzhun Control Display: LED high-definition LCD display screen, intuitively displaying parameters such as speed, time, centrifugal force, etc. It supports one click setting and multiple program storage. During operation, parameters can be modified in real time without stopping the machine, reducing operational errors.

4. Quan directional full protection: mechanical+electronic dual door lock, with self-locking cover during operation; Equipped with multiple protections for overspeed, overload, and imbalance, the centrifugal chamber is made of 304 stainless steel material, and a three-layer steel protective sleeve ensures the safety of both the human and machine in all directions.

5. Low noise and stable operation: The three-level damping and rubber damping structure effectively counteracts vibrations, ensuring smooth operation without significant displacement; Driven by a brushless DC motor, it operates with low temperature rise and low noise, creating a quiet experimental environment.

3、 Operation and usage steps

1. Power on inspection: Place the device on a stable surface, connect the power supply, check that there are no foreign objects in the centrifugal chamber and rotor, and that the pipe rack is securely installed.

2. Sample loading: Load the sample into a centrifuge tube (with a liquid volume not exceeding 75% of the nominal capacity), symmetrically place it on the tube rack, and ensure overall balance after loading.

3. Parameter setting: Close the cover and use the panel buttons to set the speed, centrifugation time, and up/down gear. The RCF value can be directly set and the equipment will automatically convert the speed.

4. Start up operation: After confirming that the parameters are correct, press the start button, and the equipment will automatically balance and start running. During operation, observe the equipment status and ensure that there are no abnormal vibrations or noises.

5. Shutdown sampling: After centrifugation is completed, the equipment automatically shuts down. When the speed returns to zero, press the unlock button to open the machine cover, remove the centrifuge tube, and complete the sample separation.

6. Shutdown cleaning: Turn off the power, clean the residual samples in the centrifuge chamber and tube rack, and keep the equipment clean and dry.

4、 Daily maintenance and precautions

1. Regularly clean the centrifuge chamber and rotor, and wipe them with anhydrous ethanol to prevent sample residue from corroding the equipment. Before cleaning, be sure to cut off the power supply.

2. Check for cracks and wear on the rotor and tube frame. If damaged, replace immediately. Do not use deformed or damaged centrifuge tubes.

3. When the equipment is running, it is forbidden to open the hood or move the device, and overloading the sample is prohibited. Ensure that the operating environment is ventilated and dry, with a temperature of 15 ℃~30 ℃ and a relative humidity of ≤ 80%.

4. If the equipment experiences abnormal vibration, noise, or alarm, immediately shut down the machine and cut off the power supply. After troubleshooting, use it again and do not operate with faults.

When the equipment is not used for a long time, the rotor should be removed and stored properly, the power should be cut off, the body should be covered with a dust cover, and placed in an environment free of dust and corrosive gases.

The Shanghai Yetuo low-speed multi tube automatic balancing centrifuge is a well-designed, stable, and widely applicable desktop centrifuge equipment. It is mainly aimed at research fields such as biochemistry, molecular biology, genetic engineering, as well as hospital laboratory departments, blood stations, central blood banks, and routine laboratories for the separation, precipitation, and concentration of body fluid samples such as serum, plasma, and urine. At the same time, it meets the preparatory testing needs of industries such as pharmaceutical hygiene and food security.
