(1) Placement and stability: Ensure that the instrument is placed smoothly and avoid vibration affecting the experimental results. The instrument should be placed on a stable workbench to avoid the influence of instrument vibration on the experiment.
(2) Power and Grounding: Use the manufacturer's configured power cord to ensure stable power supply and good instrument grounding to prevent electrical leakage and safety issues.
(3) Pre operation inspection: Before the experiment, check whether the connection of each component of the instrument is normal to avoid component detachment or damage. At the same time, check if the instrument software is installed correctly, if the power supply is functioning properly, and if the internal components are working properly.
(4) Cleaning and maintenance: Keep the instrument clean to prevent impurities from contaminating the instrument and affecting the experimental results. Regularly add bearing lubricating oil to the pump head bearing body and check the wear condition of the pump pipe regularly. If any abnormalities or damages are found, please replace them in a timely manner.
(5) Safe operation: Read and follow the steps in the instrument manual to avoid improper operation. During the experiment, keep the instrument clean and observe its operation. If any abnormalities are found, stop the machine immediately for inspection to avoid safety accidents.
(6) Shutdown and Storage: After the experiment is completed, clean the residual liquid inside the instrument and follow the instructions for shutdown and storage. If the equipment is stored for a long time, the pump tube needs to be cleaned and removed. During storage, attention should be paid to moisture, dust, and corrosion prevention.
(7) Use the correct consumables: Ensure the use of the correct board and follow the correct steps when shutting down. Before use, check the connections of each interface and ensure that the preparation and storage of samples and reagents meet the experimental requirements.
(8) Avoid contamination: Pay attention to keeping the liquid analyzer clean and avoid contamination. Clean the liquid and debris on the peristaltic pump and casing to avoid affecting the accuracy and service life of the pump head.
Pipette workstations and fully automatic separators are laboratory instruments used for liquid transfer and separation, but they have some limitations in terms of functionality, automation level, and applicabilitydifference:
function
Pipette workstation: With diverse and flexible functions, it can not only achieve precise liquid transfer and distribution, but also perform complex operations such as dilution, mixing, and gradient creation. For example, in molecular biology experiments, a series of tasks requiring multiple liquid processing steps such as nucleic acid extraction and PCR system construction can be completed.
Liquid divider: Its main function is to accurately divide a large amount of liquid into several equal parts or divide it according to specific ratios. The operation is relatively simple and focuses on the distribution function of the liquid. Commonly used for batch dispensing reagents into multiple containers, such as dividing culture media into culture dishes or test tubes.
degree of automation
Pipette workstation: a highly automated device that can be programmed to perform a series of complex pipetting tasks, achieving fully automated operations, reducing manual intervention, and improving the repeatability and accuracy of experiments. For example, in high-throughput drug screening experiments, a large number of samples can be continuously pipetted according to a preset program.
Liquid separation instrument: The degree of automation varies, and simple liquid separation instruments may only have basic liquid separation functions, requiring manual setting of parameters such as liquid separation volume and quantity; Although some advanced liquid separators can achieve a certain degree of automation, the overall automation level and functional complexity are usually lower than those of pipetting workstations.
Scope of Application
Pipette workstation: suitable for experimental scenarios with high precision requirements, complex operation steps, and large sample sizes, widely used in fields such as life sciences, drug development, clinical diagnosis, such as gene sequencing, proteomics research, etc.
Liquid analyzer: It is more suitable for rapid and large-scale distribution of liquids, and is used for batch separation of reagents and samples in routine laboratories, pharmaceutical factories, food factories, and other places, such as hospital laboratory departments for batch separation of blood samples.
