The 8-channel pipette is an experimental tool used for high-throughput liquid transfer, commonly found in molecular biology, cell biology, and chemical experiments. Accuracy is crucial when in use, especially when conducting precise experiments. Here is how to use it correctly8 pipettesSteps and techniques:

1、 Choose the appropriate pipette model and pipette head

Before use, it is necessary to confirm the required pipetting volume for the experiment. Choose the appropriate model based on the required volume. Different models have different capacity ranges. Choose a model that matches the experimental requirements, avoiding exceeding its maximum range to ensure accuracy. In addition, the choice of pipette tip is also important. The size of the pipette head should match its model to ensure good sealing and avoid leakage or sample contamination.

2、 Correctly set up

Set it to the desired volume. Most of them have a regulator that can change the volume of the pipette by rotating it. Be careful when adjusting and do not exceed the maximum range. In addition, confirm whether the volume units (such as μ L, mL) meet the experimental requirements.

3、 Regular calibration

Regular calibration is crucial to ensure the accuracy of the 8 pipettes. After a period of use, errors may occur, so standard calibration methods need to be used for inspection. The accuracy can be verified by weighing the liquid being transferred, ensuring that the amount of liquid transferred each time is consistent with the set volume.

4、 Correct use

During operation, ensure that the suction port is perpendicular to the surface of the liquid. Avoid immersing the pipette head too deeply into the liquid, as this may cause bubbles to enter the interior of the pipette, affecting the accuracy of the suction volume. When sucking liquid, a stable speed should be maintained to avoid rapid suction or discharge, which can reduce the generation of bubbles or uneven liquid. When suctioning, press the suction button and slowly release it to ensure that the pipette tip sucks in the liquid. Subsequently, move the pipette head onto the target container and release the liquid evenly.

5、 Accuracy of liquid transfer

When conducting liquid transfer, especially in high-throughput experiments, the volume of liquid in each transfer channel should be kept consistent. To ensure accuracy, the built-in locking function can be used to ensure that the transfer volume of each channel does not deviate throughout the entire process.

6、 Cleaning and maintenance

Cleaning should be carried out after each use to avoid liquid residue from affecting the experimental results. Suitable cleaning solutions and warm water can be used for cleaning, avoiding the use of highly corrosive solutions. The pipette head is also a component that is prone to contamination and should be replaced or disinfected regularly. If not used for a long time, it is recommended to conduct a comprehensive inspection and cleaning before storage to avoid damage caused by long-term storage.

The 8-channel pipette is one of the important tools in the laboratory, especially when efficient processing of multiple samples is required, it can significantly improve work efficiency. To ensure the success of precise experiments, it is necessary to be familiar with their structure and operating methods, regularly calibrate and maintain them, and follow operating procedures. By following these steps, the accuracy of the experimental results can be effectively ensured.
