Products & Reviews

PURADISC ® BIO SD is the first depth filter using the advantages of alluvial filtration in a disposable format. The filtration system removes particles (e.g. cells), impurities (e.g. HCP, DNA) and other turbid matter. This technology is also available for single-use cell separation. The system is fully scalable and disposable.

DISCSTAR ® BIO SD stainless steel housings are designed to insert PURASDISC ® BIO SD single-use filter modules. The housings are tiltable and a trolley is available to transport the modules, which guarantees easy loading and unloading of the filter modules.

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.

PURAFIX ® depth filter sheets are specially developed for use in demanding applications in the biological and pharmaceutical industries. They are characterized by their high purity and extremly low content of extractable endotoxins and ions. This product line is also available with a positive zeta potential. PURAFIX ® filter sheets are also available as lenticular modules (12" and 16" PURADISC ® ).

The NOVOX ® CP is a high precision plate & frame filter, designed for pharmaceutical and other critical applications. This filter is an enclosed filtration system completely sealed for CIP without filter sheets. It eliminates any drip loss and prevents the liquid from having contact with the outside environment.

DISCSTAR ® LS and H are high-capacity depth filtration systems with no drip loss. They have pharma-approved valves and pressure gauges and are therefore ideally suited for highly sensitive applications in healthcare and the pharmaceutical industry. DISCSTAR ® LS and H are the system of choice for frequently changing filtration applications.
