Claristep® Syringeless Filter, 0.45 µm Regenerated Cellulose

Claristep® Filter units are the ideal solution for sample preparation by particle removal prior to analytics. The 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. The syringeless filter and the simple manual processing enable customers to simplify their sample clarification. Version 06FT---96 has a pore size of 0.45 µm and a package size of 96 non-sterile filters. Units can be sterilized by autoclaving or EO.

Make light work of a tedious task. Claristep® Filter units allow syringeless filtration with shortest contact time of filtrate and filter. They are composed of chemically stable components allowing filtration of aqueous liquids as well as harsh solvents. The reservoir and lid parts consist of one piece made of PP (polypropylene). In addition the lid part has a sealing made of TPE (thermoplastic elastomer) which enables a light lid closure. By closing the lid, the sample is filtered through the tightly connected filter membrane and collected by a receiving vial of choice.
