Choose a filter suction, if you choose the wrong pipette suction type, the accuracy of even a better calibrated filter suction can be ruined. Depending on the experiment you are conducting, the wrong suction head type can also make your straws a source of contamination, resulting in wasted valuable samples or reagents, or even physical injury to you in the form of repetitive stress injury (RSI).

Currently there are many different types of filter suction tips available on the market, you need to know which straw is best for your situation, which is the purpose of our pipette knowledge selection here. So that you can choose the correct pipette element suction, and prevent unnecessary experimental errors and other problems.

Select a high quality pipette suction to ensure precision and accuracy. Precision and accuracy are the first things to consider when considering which tip type to choose. If there is any change in the shape of the pipette suction end between batches or within batches, your pipette will be inaccurate. It's a matter of manufacturing precision and quality control, and as with any manufacturing process, manufacturing precision and quality control costs money. So it's best to stay away from cheap products, after all, you get what you pay for.

If the cartridge suction does not fit your particular particular pipette, it may affect the accuracy of the pipette. If the seal between the pipette tube and the suction head is poor, inhaled air may escape, preventing the correct amount of liquid from being sucked out. So the final volume assigned is not infallible. Choosing the right tip for your pipette can be tricky.
