Sartopure® PP3 Capsule 8 µm Size 4

Sartopure^® PP3 Capsules

Sartopure^® PP3 Capsules are compact, ready-to-use polypropylene fleece prefilters designed for particle reduction in pharmaceutical and biopharmaceutical process streams. The capsule format supports convenient handling for laboratory, development and small-volume filtration steps where an enclosed device is preferred. With retention ratings from 0.45 µm to 50 µm, Sartopure^® PP3 Capsules help reduce particulate load and support protection of downstream membrane filters and process equipment.

Main Formats:

• Capsule Format: Enclosed, ready-to-use filter units for small-scale filtration tasks, process development and limited-volume applications.
• Retention Ratings: Available from 0.45 µm to 50 µm to support different particle reduction requirements and process fluid characteristics.
• Compact Design: Suitable for workflows where limited hold-up volume, easy installation and practical handling are important.
• Scalable Product Family: Part of the Sartopure^® PP3 platform, enabling alignment with larger formats such as Midicaps^®, Maxicaps^® and filter cartridges.

Applications:

• Downstream Filter Protection: Used as a prefilter upstream of membrane filters to help reduce particle burden before final filtration steps.
• Biopharmaceutical Clarification: Suitable for clarification tasks in vaccine production, viral vector processing, including lentivirus applications, and other biopharmaceutical workflows.
• Pharmaceutical Process Filtration: Applicable for ophthalmic solutions, large-volume parenterals, antibiotics, solvent-containing streams and other product-contact filtration steps.
• Process Development: Supports screening and evaluation of polypropylene fleece prefiltration before transfer to larger Sartopure^® PP3 formats.
• Small-Volume Processing: Designed for laboratory-scale and limited-volume applications where a compact disposable format is useful.

Materials Used:

• Filter Medium: Polypropylene fleece with a multilayer structure for particle reduction and dirt-holding capacity.
• Support and Housing Components: Polypropylene construction, supporting broad chemical compatibility.
• O-Rings: Silicone as standard, with EPDM or fluoroelastomer options depending on configuration and process requirements.
• Product-Contact Design: All-polypropylene filter construction supports use in regulated pharmaceutical and biopharmaceutical applications.

Advantages:

• Broad Retention Range: 0.45–50 µm options allow adaptation to different clarification and prefiltration needs.
• Broad Chemical Compatibility: Polypropylene materials support use with many acids, bases and solvents within specified operating conditions.
• Low Unspecific Binding: Helps support product recovery in sensitive biopharmaceutical process streams.
• Low Extractables Profile: Designed for product-contact filtration applications.
• Ready-to-Use Handling: Capsule format simplifies installation and reduces the need for separate reusable housings.
• Dirt-Holding Capacity: Multilayer fleece design supports particle loading and can help manage prefilter changeout frequency depending on process conditions.
• Sterilization Options: Suitable for autoclaving within specified limits for the selected capsule configuration.

Together, these features make Sartopure^® PP3 Capsules a practical prefiltration option for particle reduction, process development and downstream filter protection in biopharmaceutical and pharmaceutical workflows.
