The role of pipettes in pipette workstations

The pipette pipetting workstation is an experimental equipment that integrates high-precision pipetting technology and automated control technology. Its core advantage is that it combines the excellent performance of pipettes in precise measurement and transfer of liquids, and the simplicity of the automated workstation. Remarkable ability in complex experimental procedures and improving work efficiency. As the core component of the workstation, the pipette plays a vital role in ensuring the accuracy and reliability of liquid manipulation.

1. Components of pipette pipetting workstation 1. Pipette: a precision pipe used to absorb and discharge liquids. Pipettes of different specifications and materials can be selected according to experimental needs. 2. Control system: including computers, controllers and other hardware devices, as well as corresponding software programs, used to control the operation of the pipette and the operation of the entire workstation. 3. Operating platform: used to place samples and reagents to be processed, as well as pipettes and other experimental equipment. 4. Auxiliary equipment: such as cleaning devices, waste liquid collection devices, etc., used to keep the workstation clean and hygienic.

2. Pipette Pipette of pipetting workstation 1. Basic structure of pipette Pipette is usually made of a slender glass tube or plastic tube, and may have an enlarged part in the middle to increase stability. The lower end of the pipette is tip-shaped, which is used to insert into the liquid to draw the liquid; the upper end of the pipe neck is engraved with a marking line, which is an accurate mark of the volume of the liquid taken. Commonly used pipette specifications include 1mL, 2mL, 5mL, 10mL, 25mL and 50mL, etc. Choose the appropriate specifications according to experimental needs. 2. Working principle of pipette The working principle of pipette is based on its precise graduation system and good sealing performance. When using it, first insert the pipette into the liquid to be taken, and use an ear cleaning ball or vacuum pump to suck the liquid into the pipe until the liquid level reaches the marked position. Then, remove the liquid with the pipette and remove the excess liquid at the tip against the wall. Finally, insert the pipette into the receiving container and release your fingers to allow the liquid to flow out into the receiving container. In this way, the volume of liquid pipetted can be precisely controlled. 3. The role of pipettes in pipetting workstations In pipetting workstations, pipettes play an important role as the core tool. It uses an automated control system combined with a pipette to achieve high-precision, automated transfer of liquids. Specific functions include: (1) Precise pipetting: The high-precision graduation system of the pipette ensures the accuracy of each pipetting and reduces human errors. (2) Automated operation: Through preset programs and control systems, pipettes can automatically complete operations such as pipetting, dispensing, and mixing, improving experimental efficiency. (3) Multi-channel processing: Some pipetting workstations support multi-channel pipettes and can process multiple samples at the same time, further improving experimental efficiency. 4. Use and maintenance of pipettes In order to ensure the accuracy and extend the service life of pipettes, they need to be used and maintained correctly. Specific details include: (1) Inspection before use: Check whether the mouth and tip of the pipette are damaged. If they are damaged, they cannot be used. Also check the pipette's accuracy level and graduation mark position. (2) Cleaning and calibration: The pipette needs to be cleaned before and after use to remove dirt and residual liquid. Also, calibrate the pipette regularly to ensure its accuracy. (3) Correct operation: When using a pipette, you need to follow correct operating methods, such as avoiding inhalation of air, controlling the pipetting speed, etc. (4) Proper storage: After use, the pipette should be cleaned and properly stored in a dry, clean environment, away from direct sunlight and high temperature baking.

When discussing the operation and performance of a pipette workstation, we cannot but emphasize the crucial importance of the pipette as its core component. The pipette, a seemingly simple but extremely precise tool, is not only the basis for precise operation of the workstation, but also an important guarantee for the reliability of experimental results. By closely cooperating with the automated control system, pipettes can flexibly respond to various complex pipetting needs in the workstation, achieve precise measurement and rapid transfer of liquids, and pave a solid path for scientific research exploration and technological innovation.
