The pipette automatic stretching machine is a device that can automatically complete the stretching and retracting of the pipette. Through the mechanical structure, it realizes the automatic operation of the pipette, which greatly improves the experimental efficiency. In addition, the equipment also has the characteristics of high precision and good stability, which provides a strong guarantee for the reliability of the experimental results.

　　The pipette automatic stretching machine has a wide range of application scenarios, involving biology, chemistry, pharmaceuticals and other fields. In research, it can help experimenters transfer liquids quickly and accurately, reduce errors, and improve the accuracy of experimental results. In production, the pipette automatic stretching machine can also realize the efficient transfer of liquids, improve production efficiency and reduce costs.

　　The operating principle of the pipette automatic stretching machine is mainly to realize the automatic operation of the pipette through the mechanical transmission system. Specifically, when a liquid needs to be transferred, the operator simply inserts the pipette into the device and presses the start button. At this point, the device will automatically stretch the pipette to the preset length. While stretching, the device also precisely controls the elongation of the pipette to ensure the accuracy of pipetting. When liquid transfer is complete, the device automatically retracts the pipette, returning it to its original shape.

　　The advantages of the pipette automatic stretching machine lie in its automation, high precision and good stability. First of all, the device can realize the automatic operation of the pipette, which reduces the cumbersome steps of manual operation and improves the experimental efficiency. Secondly, the high-precision control of the equipment can effectively reduce the liquid transfer error and improve the accuracy of the experimental results. Finally, the pipette automatic stretching machine has better stability and can maintain stable performance during long-term use.
