The six channel high-precision microinjection pump is a device commonly used in biomedical, chemical analysis, and drug development fields, which can accurately control the flow rate and injection speed of multi-channel liquids. Its main function is to inject liquid into the reaction system at a precise flow rate, suitable for various experimental and production needs. The following is the operation process of a six channel high-precision microinjection pump:
1. Equipment preparation
Check equipment: Ensure that the infusion pump is not damaged and all channels are in good condition.
Install syringe: Select the appropriate syringe according to the experimental requirements and install it correctly onto the pump. A six channel infusion pump requires the installation of six syringes, each connected to an independent liquid channel.
Connecting tubing: Ensure that all syringe tubing is securely connected and there is no leakage. According to the needs, infusion tubes of different lengths and materials can be connected.
2. Set injection parameters
Select injection mode: According to the experimental requirements, choose the working mode of the injection pump (such as continuous injection, quantitative injection, gradient injection, etc.).
Set flow rate: Set the flow rate for each channel. The six channel infusion pump allows each channel to independently set the flow rate, and the flow rate or velocity of individual channels can be adjusted as needed.
Set injection volume: Enter the volume of liquid to be injected for each channel. The system will automatically calculate and execute the injection task based on the set flow rate.
Set time control: For experiments that require precise control of injection time, the total injection time, injection time for each stage, or interval time can be set.
3. Debugging and Calibration
No load operation: Before starting the experiment, perform a no-load operation to check whether the injection in each channel is smooth and ensure that there is no liquid leakage.
Calibration flow rate: Some high-precision microinjection pumps require calibration to ensure the accuracy of liquid flow rate. Standard liquid flow meters can be used for calibration to ensure that the flow rate provided by the equipment is consistent with the set value.
Test Run: Before actual operation, conduct a short test run to ensure that all parameter settings are correct and the equipment is running normally.
4. Formal injection
Start injection: Ensure that the device is connected to the liquid source and begin injecting the liquid at the set flow rate and volume. The operation interface will display the real-time status, flow rate, volume, and remaining time of each channel.
Real time monitoring: During the experimental process, monitor the status of equipment and the injection of liquids. Some six channel infusion pumps are equipped with an alarm function, which will automatically sound an alarm when the liquid flow rate is abnormal or blocked.
Adjust flow rate: If the experiment requires dynamic adjustment of flow rate, the flow rate can be adjusted in real time through the pump control panel.
5. Maintenance and cessation
Stop injection: After the set injection task is completed, stop the equipment and turn off the injection pump. At this point, it is necessary to ensure that the syringe and tubing are completely emptied to avoid liquid residue affecting the next use.
Cleaning and maintenance: Regularly clean syringes and pipelines to avoid cross contamination caused by liquid residue. In different experiments, when using different solvents, corresponding cleaning solutions need to be used to clean the equipment.
Check the equipment: After each use, check the operating status of the equipment and injection system to ensure that there are no blockages or leaks.
6. Common troubleshooting
Blockage issue: If there is abnormal flow or inability to inject liquid, it may be due to pipeline or syringe blockage. At this point, it is necessary to check and clean the blocked area to ensure that the liquid can flow smoothly.
Unstable flow rate: If the flow rate fluctuates greatly, check whether the pump's drive system, power supply, and liquid source are stable, and recalibrate the flow rate if necessary.
Liquid leakage: Check whether the connection and pipeline of the syringe are sealed, and repair or replace damaged parts in a timely manner if leakage problems are found.
summary
The operation process of the six channel high-precision microinjection pump is relatively simple, but in order to ensure accuracy and safety, the equipment needs to be carefully inspected before and after each use, and regularly maintained and cleaned. Through reasonable parameter settings and control, precise liquid injection can be achieved to meet the needs of experiments and production.
