1. RPBS-B: Pre-set rotational speed and time.
2. RPBS-C: Heat dissipation holes enable rapid heat dissipation to ensure continuous operation without overheating. The microcomputer control system offers overload safety protection and automatic memory function.
3. RPBS-D: The torque of the top penetration hole can reach 100 N.cm. It is only necessary to adjust the height of the stirring paddle, rather than that of the machine head.
4. RPBS-F: Short press the knob for switching, long press the knob for starting, and single press during starting for stopping.
5. Full View LCD Color LCD Screen: The tempered glass panel features high-definition digital display, presenting an intuitive and clear view.
6. DC brushless motor: It starts smoothly and effectively prevents sample spillage.
7. Universal chuck: It is self-locking and adjustable, with simple loading and unloading, and is anti-corrosion and wear-resistant.

Working Environment Conditions:
1. Ambient Temperature: Generally, it ranges from 5°C to 40°C. Drastic temperature fluctuations should be avoided to ensure the equipment operates under a stable temperature.
2. Relative Humidity: Typically, it should not exceed 80% RH. Environments with high humidity should be evaded to prevent the equipment from being dampened or corroded.
3. Placement Location: It ought to be placed on a stable and level laboratory bench.
4. Surrounding Environment: Direct sunlight, strong airflows, high concentrations of dust, and corrosive substances should be avoided.

Precautions:
1. Inspection of Equipment: Ensure that the exterior of the stirrer is free from damage, and the power cord, plug, and grounding wire are in pristine condition. The power voltage and frequency should conform to the equipment specifications.
2. Installation of Stirring Paddle: Select the appropriate stirring paddle in accordance with the experimental requirements and ensure its firm installation.
3. Placement of Container: Position the container to be stirred beneath the stirrer and guarantee its stability.
4. Activation of Stirrer: Increase the rotational speed gradually to prevent the liquid from splashing.
5. Monitoring of Stirring Process: Pay close attention to the operational state of the stirrer to avoid overload. Cleaning and Maintenance
6. Cleaning of Equipment: Clean the stirrer promptly after usage to avoid residues that might affect the subsequent operation.
7. Regular Maintenance: Periodically inspect the mechanical and electrical components of the equipment.
8. Avoidance of Contact: Do not come into contact with the stirring paddle during operation.
9. Storage Conditions: Store in a dry and clean environment. Moisture Avoidance: Prevent dampness or corrosion.
