Eight-channel pipetting equipment composition and instructions for use

The eight-channel pipette is a precision liquid handling tool widely used in laboratories. It is mainly used to absorb and distribute multiple samples at the same time to improve experimental efficiency. This article will introduce in detail the composition and usage instructions of the eight-channel pipetting device to help you better understand and use this important tool.

1. Equipment composition

1. Handle and display

The handle of the eight-channel pipette is ergonomically designed, comfortable to hold and easy to operate. The handle is usually equipped with a display screen to display the pipetting volume and other setting information, allowing users to monitor and adjust operating parameters in real time.

2. Pipette tips and pipette tips

The pipetting head is the core part of an eight-channel pipette and consists of eight independent channels, each equipped with a tip. Tips are usually disposable and made of high-quality plastic materials to ensure the accuracy and reliability of experiments.

3. Calibration and adjustment devices

To ensure pipetting accuracy, the eight-channel pipette is equipped with a calibration and adjustment device. Users can regularly calibrate pipettes through these devices to ensure that the volume pipetted each time is within the set range.

4. Power supply and charger

Some high-end eight-channel pipettes have built-in batteries and are equipped with dedicated chargers to maintain the continuous working ability of the device during long-term use. This design is particularly suitable for high-intensity laboratory work environments.

2. Instructions for use

1. Startup and Setup

Start the pipette by pressing the power button on the handle. After starting up, the display lights up and shows the current pipetting volume setting. Users can adjust the pipetting volume through the adjustment button on the handle to ensure that it meets experimental requirements.

2. Install the suction head

Attach the eight tips securely to the pipette head, making sure each tip is fully inserted and not loose. Pipetting accuracy can be improved by using appropriately sized tips.

3. Aspirate and dispense liquids

Insert the pipetting tip vertically into the sample liquid and gently press the aspiration button on the handle to allow the liquid to be sucked into the tip. After the liquid is aspirated, move the pipetting head above the target container and press the dispensing button to evenly distribute the liquid into the target container. During this process, keep the pipetting head vertical to avoid liquid loss caused by tilting.

4. Replace tips and clean

After completing a pipetting operation, if you need to replace the tip, you can press the eject button on the handle to eject the old tip. Continue using a new tip. Regularly clean and maintain pipettes, especially the pipette heads and suction tips, to prevent cross-contamination and ensure the accuracy of experiments.

5. Calibration and Maintenance

Regularly check the calibration status of your pipettes and make necessary adjustments using the calibration device. In terms of maintenance, avoid violent collisions with pipettes, keep them dry during storage, and avoid high-temperature environments to extend the service life of the equipment.

3. Precautions

Avoid cross-contamination: Always change tips each time you use a different sample, and clean equipment before and after operation.

1. Accurate calibration: Calibrate the pipette regularly to ensure the accuracy of each pipetting.

2. Correct operation: Keep your hands steady during operation to avoid rapid aspiration or dispensing, which will affect the pipetting accuracy.

3. Regular maintenance: Keep the pipette clean and in good condition to extend the service life of the equipment.

4. Conclusion

As an indispensable tool in the laboratory, the eight-channel pipette greatly improves experimental efficiency through its multi-channel design. During use, strictly follow the equipment composition and instructions for use, which can effectively ensure the accuracy and reliability of experimental results. Regular calibration and maintenance can extend the service life of the equipment and improve the overall efficiency of the experiment. We hope that the detailed introduction in this article will help you better understand and use eight-channel pipettes, and bring convenience to your experimental work.
