As a common tool in the laboratory, the pipette filter head can accurately control the transfer and distribution of liquids. However, in the process of use, there are several points that need special attention.

First, be sure to check the cleanliness of the pipette before use. Suction heads that are not properly cleaned and disinfected may introduce impurities or bacteria that can interfere with the accuracy of experimental results. Therefore, it is recommended to thoroughly clean and disinfect the suction head before each use.

Secondly, the appropriate size of the suction head should be selected. Different sizes of suction heads are suitable for different volumes of liquid, and improper selection may lead to inaccurate suction or leakage. Therefore, when selecting the suction head, the appropriate size should be determined according to the specific needs of the experiment.

In addition, controlling the depth of the suction head is also crucial. During operation, ensure that the suction head is just below the liquid level to avoid air inhalation or foam formation. At the same time, avoid inserting the suction head too deeply to avoid damaging the pipette or damaging the container.
