Corning® filtered IsoTip™ pipet tips feature an inert, hydrophobic bonded-fiber barrier that prevents aerosolized contaminants from coming in contact with air displacement pipettors. Ideal for applications where avoidance of cross contamination is critical, such as DNA amplification and radioisotope handling. Packaged sterile and certified RNase-/ DNase-free and nonpyrogenic. Filtered IsoTip™ Plus tips (Cat.No. 83-4810) are designed for use with 2-20µL, 10-100µL, and 20-200µL pipettors, eliminating the need to stock three different filter tips.
