Prevent liquid backsuction contamination:

During the use of the pipette, due to improper operation or accidental circumstances, the liquid may backsuck. The suction head with filter element can effectively block the anti-suction liquid, so that it can not enter the pipette inside. For example, when conducting nucleic acid detection experiments, the samples are precious and contain a large number of bioactive substances, which will not only contaminate the pipette, but also lead to deviations in subsequent experimental results. The filter element acts as a barrier to prevent this from happening, ensuring that the pipette is clean and avoiding subsequent experiments due to pipette contamination.

Avoid cross contamination:

In biological experiments, it is often necessary to deal with a variety of different samples, such as blood samples from different patients, microbial samples from different strains, etc. The use of a suction head with a filter prevents cross-contamination between different samples through the pipette. Even when multiple samples are continuously operated, the filter element can prevent the residue of the previous sample from entering the next sample, ensuring the independence and purity of each sample, thus improving the reliability and repeatability of the experiment.

Filter impurities:

Some samples may contain small particles of impurities, cell debris, or other insoluble substances. The suction head with a filter element can initially filter the absorbed liquid, intercepting these impurities and making the liquid entering the pipette more pure. This is very important for some experiments that require very high sample purity, such as cell culture, protein purification, etc., to avoid adverse effects of impurities on experimental instruments and experimental results.

Protect pipette internal structure:

When the suction head is used without a filter element, particles, vapors or chemicals in the liquid may enter the inside of the pipette, corroding or wearing key components such as the piston and seal ring of the pipette, shortening the service life of the pipette. The filter element can block these harmful substances, reduce the risk of damage to the internal parts of the pipette, reduce the frequency of maintenance and replacement of parts, save experiment costs, and improve the use efficiency and stability of the pipette
