These aerosol tips provide you with complete protection from sample carry-over. Incorporating a robotically inserted 10 μm filter with a sponge-like porous pathway. The tips have such a small pore they even block fluids in the unlikely event that you should over pipet. Proven in independent studies to block aerosol contamination but unlike some leading brands of self-sealing aerosol resistant pipet tips they have no cellulose gum, toluene solvent, or colored dyes in the filter to mix with and contaminate your sample. Also, unlike self-sealing aerosol tips, our tips can be autoclaved in a steam autoclave. And they will not wick fluids like cellulose-filled aerosol resistant tips so you don’t have to worry about how you hold your pipettor.
