F3 pipette is a precision instrument commonly used in laboratories, widely applied in fields such as molecular biology, chemical analysis, medical testing, etc., for accurate suction and transfer of liquids. Proper use can not only improve the accuracy of experiments, but also extend the service life of instruments. Here isF3 pipetteThe operation guide and skills.

1、 Preparation before use

1. Choose the appropriate pipette: Select a pipette with a suitable volume range according to the experimental needs. Ensure that the pipette (tip) used matches the pipette to avoid errors.

2. Calibration pipette: Before use, especially during high-precision experiments, it is essential to check the calibration status. The accuracy can be verified by weighing a known volume of water. If any deviation is found, it can be adjusted according to the calibration method provided by the manufacturer.

3. Installation of pipette: Gently insert the pipette into the tube opening to avoid damage caused by excessive force.

4. Check the status of the pipette: Ensure that the button and adjustment knob are in normal working condition, and the rebound effect of the button should be good.

2、 Procedure for pipetting operation

1. Set volume: According to the experimental requirements, use the adjustment knob to adjust the desired pipetting volume. When adjusting, rotate slowly to ensure accuracy to the desired volume. When adjusting, avoid excessive rotation to avoid damaging the knob.

2. Liquid suction: Place the suction head vertically into the liquid, press the suction button, slowly release the button, and allow the liquid to be sucked into the pipette. Be careful not to let the suction head touch the container wall or bottom when sucking liquid, as this can reduce the generation of bubbles and improve the accuracy of pipetting.

3. Discharge liquid: Place the suction head into the receiving container and press the transfer button to release the liquid. Ensure that the liquid is discharged and avoid leaving any residue. If more precise operation is required, you can press the discharge button and continue to press it slightly to ensure that the residual liquid in the suction head is released.

4. Cleaning the pipette: After each use, the pipette should be replaced promptly and the surface should be cleaned. Regularly clean the internal structure to avoid liquid residue affecting accuracy.

3、 Usage skills

1. Avoid sucking too much liquid: When using, avoid sucking too much liquid, especially when approaching the maximum volume, as the liquid is prone to inhaling bubbles or causing errors. Try to use an F3 pipette that is close to the required volume.

2. Avoid vigorous operation: Do not press the suction button or quick release button vigorously during the operation, as this can easily generate bubbles and affect the accurate suction of the liquid. Try to maintain smooth operation.

3. Use slow release suction button: When suctioning liquid, release the suction button slowly and smoothly to avoid bubbles in the liquid. During operation, avoid tilting the pipette to prevent the formation of bubbles.

4. Regular calibration: To ensure accuracy and stability, it is recommended to calibrate it regularly and conduct performance testing. Especially after prolonged use, it is crucial to regularly check the accuracy.

Proper use of the F3 pipette can not only improve the accuracy of experimental data, but also avoid equipment damage or operational errors. By selecting appropriate pipettes, precise volume setting, stable operation, regular calibration and maintenance, etc., the reliability and service life of the experiment can be maximized.
