The laboratory high-speed centrifuge, as a key separation equipment in the fields of biology, chemistry, and medicine, achieves efficient separation of trace samples through the centrifugal force generated by the high-speed rotation of the rotor. Its performance stability directly affects the reliability of experimental results. Yichen InstrumentTGL-16/YXJ-2High speed centrifuge with16000r/minThe maximum speed and intelligent control system are the core, making it the preferred tool in scientific research and production scenarios. The following analysis will be conducted from two aspects: technical characteristics and maintenance strategies.

1、 Core Performance Characteristics: Balancing Precise Separation and Security Protection

DC brushless motor drive, with long-lasting power and low noise

The equipment adopts a DC brushless motor, which has a longer lifespan compared to traditional brushed motors3Doubling and operating noise≤60dBIts maintenance free feature reduces long-term usage costs, making it particularly suitable for high-intensity experimental scenarios such as gene sequencing and protein purification that require continuous operation.

Microcomputer intelligent control, parameter free setting

The speed can be pre selected through the LCD display screen（1000-16000r/min）, Time（1-99Minutes) and centrifugal force（500-21000×g）, support10Adjust the lifting and lowering speed. For example, in cell fragment separation experiments, stepwise acceleration can be used（2000r/min/Avoid activity loss caused by severe shaking of the sample during the stage.

Multiple security protection systems

The stainless steel container chamber is equipped with an electronic door lock that automatically locks when the rotor is not stationary, preventing sample splashing caused by accidentally opening the lid. The warning and alarm function can monitor the speed deviation in real time±50r/min）In an unbalanced state, when the quality difference exceeds10gAutomatically stop the machine and display a fault code.

2、 Full cycle maintenance plan: key measures to extend equipment lifespan

Daily cleaning and storage standards

After each use, it is necessary to use75%Wipe the rotor and inner cavity with alcohol to avoid cross contamination caused by protein or nucleic acid residues. The equipment should be stored at a certain temperature5-35℃Humidity≤70%RHIn the environment where it is not in use for a long time, it needs to be run weekly10Minutes to prevent the motor from getting damp.

Regular inspection and replacement of rotors

Angular rotor is used every time500Secondly or2After the year, it is necessary to conduct dynamic balance testing, and for horizontal rotors, every300Check the aging condition of the sealing ring. For example, a university laboratory failed to replace the deformed rotor in a timely manner, resulting in severe vibration during the centrifugation process and causing a rotor rupture accident.

Calibration and software upgrade

Every year, a professional organization is commissioned to calibrate the speed sensor and temperature control system to ensure the error between the actual value and the displayed value≤±1%. ThroughUSBThe interface update control program can fix known vulnerabilities and optimize the acceleration and deceleration curves, improving separation efficiency.

Emergency handling of faults

If there is an inability to start, first check if the power cord is loose, and then confirm the doorIs the lock completely closedHehe. For the problem of decreased centrifugal effect, it is necessary to recalibrate the rotor model parameters and clean the residue on the centrifuge tube wall.
