Preparing samples by particle removal is an essential step prior to nearly all analytical techniques, such as high pressure liquid chromatography (HPLC). Sartorius has developed a new, easy-to-use and straightforward filtration setup. The manually operated Claristep® Filtration System consisting of a station and filter units offers a novel way for clarifying your samples prior to analysis. Claristep® Filters are suitable for small sample volumes of 60 to 600 µl and are used without syringe. By using the accessory Claristep® Station up to eight samples can be processed simultaneously.
