Sartolab® P20 are ready-to-use pressure filtration units mainly used for sterile filtration applications of media and buffers. They are currently offered in 2 variations: with a polyethersulfone and Cellulose Acetate membrane, with 0.2 μm or a 0.45 μm pore size. Due to commercial considerations and to streamline the portfolio, we have decided to discontinue these cellulose acetate filtration units end of the year 2020.
