Sartopure® PP3 Maxicaps® 20 µm 30"

Sartopure^® PP3 Maxicaps^®

Sartopure^® PP3 Maxicaps^® are ready-to-use polypropylene fleece prefilters designed for particle reduction in pharmaceutical and biopharmaceutical process streams. The enclosed capsule format supports convenient handling and helps reduce the need for separate stainless steel housings. With retention ratings from 0.45 µm to 50 µm, Sartopure® PP3 Maxicaps^® help lower particulate load and support protection of downstream membrane filters and process equipment.

Main Formats:

• Maxicaps^® Format: Enclosed, ready-to-use capsule devices for process filtration in development, pilot-scale and manufacturing environments.
• Retention Ratings: Available from 0.45 µm to 50 µm to support different particle loads, feed streams and prefiltration requirements.
• Filtration Areas: Offered in multiple sizes to support a range of process volumes and throughput needs.
• Connection Options: Available with different connector configurations for integration into existing process setups.
• Scalable Platform: Part of the Sartopure^® PP3 product family, supporting alignment with cartridges, Midicaps^®, Mini Cartridges and Capsules.

Applications:

• Downstream Filter Protection: Used upstream of membrane filters to help reduce particle burden before final filtration steps.
• Biopharmaceutical Clarification: Suitable for clarification in vaccine production, viral vector processes, including lentivirus applications, and other biopharmaceutical workflows.
• Pharmaceutical Process Filtration: Applicable for ophthalmic solutions, large-volume parenterals, antibiotics, solvents and other product-contact filtration steps.
• Process Development and Scale-Up: Supports evaluation and implementation of polypropylene fleece prefiltration from smaller formats to larger process setups.
• Enclosed Processing: The Maxicaps^® design supports convenient filter handling where capsule-based filtration is preferred.

Materials Used:

• Filter Medium: Polypropylene fleece with a multilayer structure for particle reduction and dirt-holding capacity.
• Support, Core and Housing Components: Polypropylene construction for 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 Capsule Format: Maxicaps^® devices simplify setup and eliminate 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 or in-line steam sterilization within the specified limits for the selected configuration.

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