Sartorius Sartopure PP3 Filter Capsule 20 um Size 5 Pack of 5 Filters

Description

Sartorius 5051320P5–00–B Sartopure PP3 Capsule – 20 µm, Size 5

The Sartorius 5051320P5–00–B is a premium, ready-to-use filter capsule designed for the high-efficiency clarification and pre-filtration of biological solutions. At the core of this Size 5 capsule is the Sartopure PP3 pleated depth filter matrix. Constructed entirely from polypropylene, it features a unique, multi-layered fleece geometry tailored to trap heterogeneous particles, colloids, and cellular aggregates without causing rapid pressure buildup, culminating in a reliable 20 µm retention rating. Housed in a durable, self-contained polymer shell with integrated 1/4-inch stepped hose barbs, this capsule eliminates the need for stainless steel filter housings and associated cleaning validation. The all-polypropylene construction ensures broad chemical compatibility and a very low extractables profile, making it a seamless, plug-and-play solution for pilot-scale bioprocessing, buffer preparation, and downstream equipment protection.

Technical Performance and Design

• All-Polypropylene Construction: Both the filter media and the outer housing are manufactured from high-purity polypropylene, offering excellent chemical resistance to strong acids, bases, and various organic solvents.

• High Throughput Fleece: The advanced depth fleece material is engineered for high flow rates and low differential pressure, which reduces the total filtration area required and improves overall process economy.

• Low Unspecific Binding: The naturally low-binding characteristics of the binder-free polypropylene maximize product yield, ensuring that high-value proteins or recombinant vaccines are not lost to the filter matrix.

• Integrated Hose Barbs: Features multiple stepped hose barbs (1/4″ or 6 mm) on both the inlet and outlet, ensuring secure, leak-free connections to standard flexible silicone or PVC tubing without the need for specialized adapters.

Key Benefits & Applications

• Downstream Protection: Serves as a highly cost-effective guard 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 harvests, fermentation lysates, and crude serum preparations.

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

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