It's hard to believe that simple plastic molded disposable tips are a livelihood in the world of molecular biology, chemistry and medicine. That's right, we're talking about pipette tips. These tips create a reliable and accurate pipetting system. Pipette tips are divided into three different types, including non-sterile tips, pre-sterilized tips, and filter tips.
The most commonly used pipette tip types are non-sterile tips. They are typically used in laboratory applications where sterility is not critical 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 culture.
Filter tip
Filter tips are designed to prevent aerosol formation. Aerosols are airborne small liquid or solid particles. These particles can actually stay in the air for a long time and can be inhaled. To make matters worse, 65% of laboratory infections are caused by aerosols, usually through inhalation. Filtered pipette tips help reduce the risk of aerosol formation in the laboratory. They also protect pipette stems from contamination and reduce the risk of cross-contamination. These pipette tips are often used in contamination-sensitive applications such as forensics and clinical diagnostics.
Due to the potential for aerosol infection, we cannot stress enough the importance of enforcing safe work practices in the laboratory. This includes proper sterilization of pipettes and handling of pipette tips after use.
