Fully automated workflow and precautions for pipetting workstations

Pipetting workstations are commonly used equipment in laboratories, which can help experimenters achieve precise distribution and pipetting of liquids. When performing pipetting work, we need to follow a certain fully automated workflow, and we also need to pay attention to some matters to ensure the accuracy and efficiency of the experiment.

1. Fully automatic workflow of the pipetting workstation 1. Preparation: (1) Place the pipetting workstation on a stable table and connect the power cord. (2) Make sure the workstation is clean and tidy, and there are no distractions from other items on the desktop. (3) According to the experimental requirements, prepare the required reaction materials and containers and place them on the work platform. 2. System settings: (1) Through LCD display or PLC programming, set parameters such as capacity, speed and depth of suction and discharge during pipetting. (2) Select appropriate liquid handling heads, filters, and plates, and ensure that these parts are clean and suitable for the current experiment. 3. Pipetting operation: (1) The pipette tip or needle of the pipetting workstation will automatically absorb the set volume of reactant. (2) Accurately distribute the absorbed reaction materials to different reactors through the control of solenoid valves, air pumps and other equipment. (3) If mixing operation is required, the needle or air pump will mix, and the liquid will be fully mixed before being distributed to the designated reactor. 4. Data processing and recording: (1) Fully automatic pipetting workstations usually have data recording functions and can automatically save various parameters and results during the pipetting process. (2) Experimenters can export data for analysis and reporting as needed.

2. Precautions 1. Inspection before operation: (1) Before use, you must check whether the power supply and connecting cable of the system are normal. (2) Check whether the grating measurer and electronic balancer are correctly calibrated. (3) Ensure that the liquid level sensor can correctly measure the liquid height. 2. Safe operation: (1) Do not let any objects touch or enter the workstation, such as fingers, reagent bottle caps, etc. (2) Do not knock or apply pressure on the pipetting head to avoid damaging the equipment. (3) Before adding liquid, make sure that the adding needle has no bubbles and no residual liquid. (4) Wear appropriate personal protective equipment such as lab coats, gloves, and goggles. 3. Maintenance and maintenance: (1) The pipetting workstation should be stored in a dry environment with suitable temperature and lighting to prevent direct sunlight and moisture accumulation. (2) Carry out thorough cleaning and maintenance of the workstation every week, including cleaning pipetting heads, adding needles, filters and other components. (3) Regularly replace liquids and washing buffers, and calibrate the aspiration capacity of the pipetting head and adding needle. (4) Regularly calibrate the grating measurer, electronic balancer and liquid level sensor. 4. Consumables management: (1) The use of the pipetting workstation depends on some consumables, such as pipetting heads, liquid adding needles, plates, filters, etc. (2) These consumables will be worn or contaminated and need to be replaced in time to ensure the accuracy of the experiment and the normal operation of the equipment. 5. Comply with the operating procedures: (1) Read the instruction manual carefully before operation, and carry out environmental preparation, operation preparation and reagent preparation in accordance with the requirements of the instruction manual. (2) Comply with operating procedures and precautions during operation to avoid equipment damage or experimental failure caused by improper operation.

The smooth execution of the fully automatic workflow of the pipetting workstation and the strict compliance with the precautions are important guarantees for the success of the experiment and the safety of the laboratory. We call on every experimenter to take every link in this process seriously and promote the continuous progress and development of laboratory research with a rigorous attitude and scientific methods.
