Sartopure® PP3 Mini Cartridge 5 µm Size 7

Sartopure^® PP3 Cartrigdes

Sartopure^® PP3 Cartridges are polypropylene fleece prefilters designed for particle reduction in pharmaceutical and biopharmaceutical process streams. Installed in compatible filter housings, they support scalable prefiltration from development to manufacturing. With retention ratings from 0.45 µm to 50 µm, Sartopure^® PP3 Cartridges help reduce particulate load, support downstream membrane filter protection and provide broad applicability across product-contact filtration steps.

Main Formats:

• Standard Filter Cartridges: Designed for use in stainless steel housings and suitable for scalable process filtration setups.
• Mini Cartridges: Compact cartridge format for smaller process volumes, development work and scale-up studies.
• Retention Ratings: Available from 0.45 µm to 50 µm to match different particle loads, feed stream properties and prefiltration requirements.
• Multiple Sizes and Configurations: Offered with different filtration areas and adapter options to support integration into existing process equipment.
• Scalable Product Family: Part of the Sartopure^® PP3 platform, supporting alignment with capsule formats such as Midicaps^®, Maxicaps^® and standard 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 processing, including lentivirus applications, and other biopharmaceutical workflows.
• Pharmaceutical Process Filtration: Applicable for ophthalmic solutions, large-volume parenterals, antibiotics, solvents and other product-contact filtration applications.
• Process Scale-Up and Manufacturing: Cartridge format supports use in reusable housings for larger process volumes and established production lines.
• Equipment Protection: Helps reduce particulate exposure to downstream process equipment and filtration devices.

Materials Used:

• Filter Medium: Polypropylene fleece with a multilayer structure for particle reduction and dirt-holding capacity.
• Support, Core and End Components: Polypropylene construction to support 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.
• Dirt-Holding Capacity: Multilayer fleece design supports particle loading and can help manage filtration area and changeout frequency depending on process conditions.
• Scalable Housing-Based Use: Cartridge format is suitable for reusable housings and process setups that require defined filtration areas.
• Sterilization Options: Suitable for autoclaving or in-line steam sterilization within the specified limits for the selected configuration.

Together, these features make Sartopure^® PP3 Cartridges a practical prefiltration option for particle reduction, downstream filter protection and scalable biopharmaceutical manufacturing workflows.
