The most commonly used type of pipette tip is non-sterile tips. They are often used in laboratory applications where sterility is not important to the experiment or test being performed. On the other hand, pre-sterilized pipette tips are designed to prevent contamination. They are certified free of DNA, RNase, ATP and pyrogens. Because these pipette tips are certified free of DNA, RNase, ATP and pyrogens, they are ideal for applications that require sterility such as cell cultures.
With the possibility of infection from aerosols, we can’t emphasize enough how important it is to enforce safe work practices in the laboratory. This includes properly disinfecting pipettes after use and disposing of pipette tips.
