Sartorius Filter Capsule Sartopore 2 XLI SartoScale 25 0.2 um 6 Filters

The Sartorius 5445307IV--LX--C Filter Capsule is a specialized, single-use filtration unit designed for sterile fluid processing, particularly within process development and scale-up studies. This capsule is part of the Sartopore 2 XLI family, known for its validated sterilizing performance and long service life.

A key feature is its 0.2 µm pore size, which is the industry standard for sterile filtration, ensuring the removal of bacteria and other microorganisms from liquids. The filter membrane is typically a highly robust polyethersulfone (PES) material that provides high flow rates and low protein binding. The "XLI" designation often refers to an extended life version of the membrane, optimized for high throughput and challenging filtration streams.

This capsule is specifically in the SartoScale 25 format, meaning it is designed to mimic the performance of large-scale Sartopore 2 XLI cartridges using a small 25 cm² filtration area. This makes it an essential tool for method development, filter sizing, and scale-up trials, allowing researchers to accurately predict the performance of large filters with minimal product consumption. The Sartorius 5445307IV--LX--C capsule is a vital tool for achieving reliable and scalable sterile filtration in biopharmaceutical manufacturing.
