The multi-channel pipette is an efficient and convenient laboratory operation tool that can pipette liquids from multiple wells at the same time. It usually consists of an adjustable-capacity suction head, a volume-adjustable dispensing head and an operating lever. Its characteristics are that it can greatly improve work efficiency, reduce manual operation errors, and adapt to the working positions and habits of different users.

1. Working principle

Multi-channel pipettes work by controlling the volume of an adjustable-capacity tip via a manual lever (for manual models) or an electric controller (for electric models), thereby accurately controlling pipetting during aspiration and placement of liquids. quantity. At the same time, liquid can also be distributed through a volume-adjustable distribution head to achieve multi-channel distribution of liquid.

2. Types and specifications

Multi-channel pipettes can be divided into manual and electric types according to the operation mode. Manual multi-channel pipettes use a manual lever to control the pipetting process, while electric models use an electric controller to set the volume and dispensing mode of the pipette. In terms of specifications, multi-channel pipettes usually have a variety of specifications such as 8 channels and 12 channels to meet the needs of different experiments.

3. Application advantages

1. Improve work efficiency: Multi-channel pipettes can pipette multiple liquids at the same time, greatly shortening experimental time and improving work efficiency.

2. Reduce errors: Due to the use of automated or mechanized operations, multi-channel pipettes can reduce errors caused by manual operations and improve the accuracy of experiments.

3. Strong adaptability: Multi-channel pipettes usually have a large volume range and can adapt to pipetting needs of different volumes. At the same time, its streamlined design, light weight, simple and comfortable operation also make it suitable for different users.

4. Precautions for use

1. Before use, check whether all parts of the pipette are intact to ensure that they are not damaged or loose.

2. Select the appropriate pipetting head and number of channels according to the experimental needs to ensure the smooth progress of the experiment.

3. During the operation, attention should be paid to controlling the pipetting speed and strength to avoid bubbles or liquid splashing.

4. After use, the pipette should be cleaned and maintained in time to extend its service life and maintain good working condition.

5. Example products

1. Brand and model: Flex pipette from Opentrons

2. Main features: Modular design: Flex’s Z-axis gantry design allows users to install any two Flex single-channel or 8-channel pipettes, or configure a Flex 96-channel pipette separately according to experimental needs.

Multi-channel pipette is an important laboratory operation tool with wide application prospects and market demand. During use, we should pay attention to its working principle, type specifications, usage advantages and usage precautions to ensure the smooth progress of the experiment and the accuracy of the results.
