Sartorius Sartopure PP3 Midicaps 20 um Size 7 Pack of 4 Filters

Description

Sartorius 5055320P7–00–A Sartopure PP3 Midicap – 20 µm, Size 7

The Sartorius 5055320P7–00–A is a premium, ready-to-use Midicap capsule designed for the high-efficiency clarification and pre-filtration of biological solutions. At the core of this Size 7 capsule is the Sartopure PP3 pleated depth filter matrix. Constructed entirely from polypropylene, it features a unique, multi-layered fleece geometry with progressively tighter pore zones, culminating in a 20 µm retention rating. This graduated density acts as a highly effective trap for heterogeneous particles, colloids, and cellular aggregates without causing rapid pressure buildup. Housed in a durable, self-contained polymer shell, the Midicap eliminates the need for stainless steel filter housings and associated cleaning validation, providing a seamless, plug-and-play solution for pilot-scale bioprocessing, buffer preparation, and downstream equipment protection.

Technical Performance and Design

• Graduated PP3 Depth Media: The pleated, multi-layer polypropylene fleece captures larger debris in the outer layers and finer particles at the 20 µm inner zone, maximizing total throughput and preventing premature surface blinding.

• Midicap Size 7 Architecture: The self-contained capsule design offers a substantial effective filtration area tailored for pilot-scale and mid-volume processing, bridging the gap between small syringe filters and massive production-scale filter cartridges.

• All-Polypropylene Construction: Provides exceptionally broad chemical compatibility across a wide pH range (pH 1 to 14), allowing for the safe filtration of aggressive buffers, acids, bases, and complex organic solvents.

• Low Extractables: Manufactured without the use of binders, resins, or surfactants, ensuring that no unwanted leachables contaminate the biological product or interfere with downstream analytics.

Product Specifications

• Catalog Number: 5055320P7–00–A

• Filter Series: Sartopure PP3

• Retention Rating: 20 µm

Key Benefits & Applications

• Downstream Protection: Serves as a highly cost-effective pre-filter to drastically extend the operational lifespan of expensive 0.2 µm sterilizing-grade membranes and chromatography columns.

• Upstream Clarification: Ideal for the initial processing of moderately viscous or high-solids fluids, such as cell culture broths, fermentation lysates, and crude serum preparations.

• Closed-System Efficiency: The capsule format is easily integrated into single-use bioprocessing assemblies, minimizing exposure risks and setup time in cleanroom environments.

• Linear Scale-Up: The Sartopure PP3 materials and flow geometries provide reliable performance data that translates flawlessly to larger MaxiCaps or standard filter cartridges for commercial production.
