Filter tip
Pipettes are widely used in laboratories to measure small amounts of liquids when conducting experiments. Researchers take great care to choose a pipette that fits their needs, is ergonomic and has high quality and performance.
Since there is a lot to consider when deciding on the best model for a pipette, choosing the perfect tip for it is just as important. In order for the pipette to function properly, it is necessary to choose a tip with good chemical compatibility and match it with the pipette, so that the user can easily carry out the experiment. Users should avoid investing in inferior pipette tips as they may not be chemically compatible.
Filtered pipette tips, also known as aerosol barrier tips, have the basic purpose of protecting your pipettes from aerosols and aspiration of volatile or viscous solutions, avoiding contamination and damage to your pipettes. Filter tips are pre-sterilized, DNase/RNase-free, and fit into the proximal portion of the tip.
Filter tips serve two main purposes - they protect pipettes from aerosols and protect samples from aerosols.
Due to their functionality, filter tips are valuable for ultrasensitive applications such as polymerase chain reaction (PCR). The filter barrier prevents any cross-contamination by eliminating the opportunity to carry samples from the pipette, providing users with reliable results.
Filter tips also help new researchers conduct proper research. Often, new lab members accidentally suck reagents directly into the pipette, resulting in contamination of the pipette. To avoid this, filter tips should be fitted to the pipette as it is more cost effective if only the tips need to be discarded instead of sending the pipette for repair.
Standard and filter tips
Filter tip
Laboratories often use standard pipette tips for a variety of purposes. They can meet different performance requirements, such as high precision and reagent dispensing with wider tolerances. However, standard pipette tips may not have low retention, which in turn can lead to cross-contamination. However, as established at the outset, filter tips eliminate the risk of cross-contamination, making them suitable for sensitive applications such as clinical diagnostics.
Filter tips are also designed to prevent the formation of small particles, liquids or solids called aerosols. This is a big advantage because aerosols stay in the air for long periods of time and can be inhaled by lab users leading to infection.
Use of filter tips in COVID-19 testing
With the increasing severity of the COVID-19 pandemic, effectively testing people for the virus has become critical. For such high-risk and critical illness testing, pathologists must ensure that samples and testing equipment are not contaminated with viruses, so filter pipette tips are the best choice.
The FDA-approved COVID-19 test utilizes a PCR technique to measure RNA instead of DNA. The presence of disease is detected by RNA purified from the sample. Also, to reduce the risk of aerosol contamination, use only filtered pipette tips. With the current situation worrying, one cannot risk the chance of getting false readings. If by any chance the sample is contaminated, subsequent copies will become inaccurate, leading to false diagnoses.
Due to the need to test large numbers of samples quickly and efficiently, the Centers for Disease Control and Prevention (CDC) has directed testing centers to use filtered pipette tips. This eliminates the risk of cross-contamination between samples and also keeps laboratory personnel and equipment free from contamination.
Due to the increasing number of COVID-19 cases and high testing rates, testing centers are in desperate need of large quantities of high-quality filtered pipette tips.
