PURASPIN ® depth filtration units are designed for small scale filtration trials. They allow efficient and cost-effective depth filtration of up to 20 mL. They can be used as a depth filter unit in a centrifuge or by applying vacuum.

PURACAP ® and PURACAP ® BIO SD are filter capsules for lab and pilot scale filtration trials. The capsules are used as a tool to generate the data needed for a propper scale-up. PURACAP ® is used for standard depth filtration (sheet filtration), PURACAP ® BIO SD for alluvial filtration (e.g. clarification of cell broth).

ACTIVASORB ® depth filter sheets are used in various applications such as decolorization, deodorization or catalyst removal. This type of filter sheets contains immobilized activated carbon which allows a easy and clean handling. In addtion, treatment with immobilized activated carbon is much more efficient compared to loose carbon powder due to a forced contact of the impurities with the activated carbon.

The PURASPIN ® Test Kit contains 5 different filter sheet types for laboratory filtration tests for coarse, fine, clarifying and sterile filtration. A practical and easy-to-use tool to define the right filtration solution at an early stage in the development process.

The SCALE-UP Test Kit is a tool to find the ideal depth filter at an early stage of the process development. The test kit contains 10 different PURASPIN ® for 20 mL trials, a 2" capsule with a selection of filter sheets for verification and the necessary information for a proper scale-up calculation.
