The new Axygen® brand GEN3 multi-barrier filter pipet tips offer the ultimate in protection against cross contamination using tri-filter technology. These tips will prevent liquid or aerosol from passing through and will lock on contact. GEN3 tips effectively separate liquid from the self-sealing barrier using an additional protective layer of conventional polyethylene filter material. In addition to the self-sealing properties, our GEN3 multi-barrier pipet tips feature our exclusive Maxymum Recovery® technology which reduces the amount of reagent or sample adhering to the pipet tips. Offered in Racks, sterile, tips are nonpyrogenic and human gDNA and PCR inhibition free and DNase-/RNase-free.
