Filtering effect

Interception of impurities: It can intercept insoluble impurities, cell fragments, dust particles, etc. in the sample, ensuring the purity of the drawn sample. For instance, when drawing samples from cell culture medium, the filter element can block cell debris, preventing it from entering the pipette and affecting the accuracy of pipetting or interfering with subsequent experiments.

Microbial removal: For samples with a risk of microbial contamination, the filter element can block bacteria, fungi and other microorganisms, preventing them from entering the pipette or spreading among different samples. In microbiological experiments, such as the transfer of bacterial cultures, the filter element can effectively prevent contamination by miscellaneous bacteria.

Prevent the generation of aerosols

Avoiding cross-contamination: During pipetting operations, especially when drawing up and discharging liquids, the filter element can reduce the formation and spread of aerosols. Aerosols may carry components from the samples. If they spread in the experimental environment, they can easily cause cross-contamination among different samples or in the experimental area. For example, in genetic testing experiments, preventing the generation of aerosols can avoid mutual contamination among different DNA samples and ensure the accuracy of the experimental results.

Protecting laboratory personnel: Some samples may contain harmful or infectious substances, and the generation of aerosols can pose a threat to the health of laboratory personnel. The filter element can reduce the formation of aerosols, thereby reducing the risk of exposure of laboratory personnel to harmful substances.

Maintain the stability of the internal environment of the suction tip

Balancing air pressure: During the pipetting process, the filter element helps balance the air pressure inside and outside the pipette tip, making the suction and release of the liquid smoother. Especially when performing rapid pipetting or drawing high-viscosity liquids, it can prevent inaccurate liquid drawing or liquid splashing due to changes in air pressure.
