Claristep® Syringeless Filters

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.

Make light work of a tedious task. Claristep® Filter units are the ideal solution for sample preparation by particle removal prior to analytics. As the sensitivity of automated analytical instruments continues to improve, they increasingly require less volume to operate in order to maximize throughput. Therefore, fast clarification of small volumes that does not add leachables or extractables to the original sample is indispensable for achieving the best analytical results. The Claristep® filters are suitable for small sample volumes of 60 to 600 µl and are used without syringe. The Claristep® Filtration System can process up to eight samples simultaneously without any vacuum source or power supply. The syringeless filter and the simple manual processing enable customers to simplify their sample clarification.
