As we all know, most of the daily experiments and research work are inseparable from pipettes. The performance of the Pipette is the key that directly affects the accuracy and precision of the laboratory, and the quality of Pipette Tips plays a vital role in the pipette.
Now the most popular nucleic acid detection is inseparable from pipetting. A nucleic acid detection requires at least dozens of pipetting operations. Pipetting and repeated aspiration can easily produce aerosol (aerosol), which is invisible to the naked eye. Small liquid particles are always ignored, not only will enter the handle part of the pipette, but also very easy to contaminate the new sample with the next pipetting operation. So how can we prevent aerosol pollution? How to ensure the accuracy of pipetting? here we come to find out. First of all, we need to understand what is aerosol? Aerosol (aerosol) is a colloidal dispersion system formed by solid or liquid small particles dispersed and suspended in a gas medium, also known as a gas dispersion system. The dispersed phase is solid or liquid small particles with a size of 0.001-100 μm, and the dispersion medium is gas. Liquid aerosol is usually called mist, and solid aerosol is usually called mist. The aerosol is produced because the dispersed system in the sample diffuses into the air under the action of some external force, thereby forming a dispersed system. In the laboratory inspection process, there are many operations that will form aerosols. Filter Pipette Tips can effectively block the presence of aerosols. The filter tip adopts a tortuous channel design, which effectively blocks aerosol and sample backwashing; the uniform filter pore size will not change the pipetting resistance or affect the accuracy of pipetting; the filter tip can effectively protect the sample and make the pipetting The device is protected from aerosol cross-contamination, which is especially important in DNA amplification and sequencing. As the pipette is in use, there is a risk of sucking up liquid. Therefore, in the process of transferring different samples or reagents using the same pipette, it is necessary to use a pipette tip with a filter element to avoid cross-contamination, which is also something that must be paid attention to in the diagnosis of COVID-19. Filtered Pipette Tips not only prevent aerosol contamination, but also avoid liquid corrosion and damage to the pipette. It is mostly used for the transfer of blood samples, virus samples and other toxic and harmful liquids. Therefore, for laboratory clinical testing personnel, when doing sample testing, we must wear masks, gloves, and protective clothing. At the same time, we must also pay attention to the use of filter tips for nucleic acid extraction to ensure personal and sample safety.
