Our customers use the Sartolab P20 Plus large-volume positive pressure filter. Since the filter volume is large, it is often used in the R&D phase. There are different membrane pore sizes to choose from, and we normally recommend a pore size of 0.2 µm. The benefit of the Sartolab P20 Plus is the fast and efficient filtration. At least 5 liters of water sample can be filtered by combining with a peristaltic pump. Many of our customers also use Tangential Flow ultrafiltration membrane to pack a Vivaflow cassette to concentrate hyaluronic acid and remove impurities.
