Application Note: Comparative Investigations on the Blocking Efficiency of Filter Tips
11 May 2018
The blocking efficiency of Filter Tips is investigated using airborne particles. Filter tips mounted in air-displacement pipettes are used to prevent potential contamination of the pipette cones by e.g. DNA fragments. The more effective the filter, the less the risk of contamination. This is of utmost importance for preventing false-positive results, especially in highly sensitive PCR experiments. In this investigation Starlab TipOne 200 µl filter tips have been compared with those of nine other manufacturers.
