As an indispensable and efficient automation tool in modern laboratories, the liquid workstation's precise, fast and reliable operation capabilities have greatly improved the efficiency of scientific research and production. Before operating the liquid workstation, a series of rigorous preparations are key to ensuring the smooth progress of the experiment.

1. Preparation 1. Check the equipment: First, check whether all components of the liquid workstation are intact, such as pumps, valves, pipes, etc., to ensure that the equipment is in good working condition. 2. Wear protection: Workers should wear corresponding labor protection supplies, such as hats, masks, gloves, etc., to protect their own safety and prevent contamination. 3. Prepare reagents and samples: According to the experimental requirements, prepare the required reagents, samples and consumables, such as test tubes, pipettes, filters, etc. Make sure all containers are clean, uncontaminated and clearly labeled. 4. Connect the power supply and air source: Make sure the power supply and air source of the liquid workstation are connected properly, and perform preheating or precooling if necessary.

2. Installation and connection 1. Loading samples and reagents: Load the liquid samples and reagents to be processed into corresponding containers according to the experimental requirements, such as test tubes, bottles, etc. 2. Connect equipment: Use a special adapter or valve to connect the container containing samples and reagents to the liquid workstation, make sure there is no leakage at the connection, and check whether the valve is in the correct position.

3. Set parameters 1. Set experimental parameters: According to the experimental requirements, set various parameters on the liquid workstation, such as flow rate, temperature, pressure, etc. These parameters can be set via the touch screen, keys or computer software. 2. Check parameters: Before starting the equipment, confirm again whether all parameter settings are correct to avoid errors or deviations during the experiment.

4. Startup and operation 1. Start the equipment: Press the start button, and the liquid workstation will automatically perform sampling, distribution, mixing and other operations according to the preset program. 2. Monitoring status: During operation, monitor the working status of the liquid workstation at any time, such as flow rate, temperature, etc., to ensure the smooth progress of the experimental process.

5. Collect and process samples 1. Collect samples: After completing the preset operations on the liquid workstation, collect the processed samples into the corresponding containers. 2. Further analysis: If further analysis is required, such as chromatography, mass spectrometry, etc., the sample can be directly introduced into the analysis equipment.

6. Cleaning and maintenance 1. Turn off the equipment: After the experiment, turn off the power and air source of the liquid workstation, and disconnect it from external equipment. 2. Cleaning equipment: Use special detergent and soft cloth to clean the surface and internal pipes of the equipment, and be careful not to damage the equipment. Replace worn or damaged parts such as pumps, valves, etc. 3. Maintain equipment: Conduct comprehensive inspections and maintenance of equipment regularly to ensure that its performance is stable and reliable.

7. Records and reports 1. Record operations: During the experiment, record the operation process and experimental results of the liquid workstation in detail to facilitate subsequent analysis and summary. 2. Writing reports: Write experimental reports based on experimental data, and analyze and discuss the experimental process and results.

The above operating procedures are only general guidance. For specific operations, you should refer to the user manual of the liquid workstation or follow relevant experimental specifications. In addition, different brands and models of liquid workstations may have differences in operational details, so they should be flexibly adjusted in actual operations.
