Functions of Filtered Tips

Pipette tips are commonly used in laboratories, the choice of pipette tips and the impact of different pipette tips on the experiment. So today we will talk about why we should use filtered pipette tips, and the role of filtered tips.

The filtered tip is an upgraded version of a regular tip, i.e., a filter (usually white in color) is added to the top of the regular tip to optimize the pore size and ensure good aeration while blocking the effect. This filter is generally made of polypropylene (PP), similar to the structure of a cigarette filter.

Thanks to this filter, the pipetted sample cannot enter the interior of the pipettes, thus serving to protect the pipette components from contamination and corrosion and, importantly, to ensure that there is no cross-contamination between samples. Therefore, pipette tips with filter cartridges are also an important tool for pipetting volatile and corrosive samples.

-Safeguard the safety of experimenters.

Can reduce the spread of harmful products and maximize the personal safety of operators.

-Safeguard the safety of samples.

No heat source, no DRNase, DNase, no PCR inhibitor, to prevent cross-contamination.

-Safeguard the safety of pipette use.

Avoid liquid flushing into the cavity, prevent the pipette from being damaged by the sample, maintain the precision and accuracy of the sample, and extend the service life of the pipette.

-In the processing of demanding molecular biology samples such as PCR samples.

-Application in the handling of hazardous samples such as radioactive, biotoxic, corrosive, volatile, etc.

-In all contamination-sensitive molecular biology applications where the use of filter tips is mandatory.

The filtered tips help reduce the possibility of fume formation and prevent aerosol contamination, which in turn results in protection of the pipette shaft from cross-contamination. The filter tips are autoclaved after packaging for enhanced protection of biological samples. In addition, the filter barrier prevents sample carryover from the pipette, thereby preventing PCR contamination

Viruses are infectious, and if filter tips are not used to isolate viruses in samples during virus detection, this can result in virus transmission through the pipette, which can have serious implications. Since the samples are different from each other, the filtered tips can effectively avoid cross-contamination of the samples during pipetting, which is also a very important part of our daily laboratory testing for the new coronavirus.
