Sartorius SartoScale Sartoguard PES 0.2 um Pack of 4 Filters

The Sartorius 5445307FS--FF--M SartoScale Sartoguard PES 0.2 µm is a filtration unit designed to achieve sterile filtration of liquids in a scalable manner. This unit is a combination of a SartoGuard prefilter and a Sartopore membrane, both integrated within the SartoScale housing, providing a reliable and efficient filtration solution.

The SartoScale designation indicates that the unit is part of Sartorius's SartoScale product line, which is specifically engineered to facilitate seamless scale-up from small-scale laboratory trials to large-scale industrial production. This design ensures that the filtration performance remains consistent as the process moves from development to manufacturing. The SartoGuard component refers to a prefilter layer incorporated within the unit. Prefilters play a crucial role in removing larger particles from the liquid stream, effectively protecting the downstream sterilizing-grade filter and significantly extending its operational lifespan.

The PES 0.2 µm specification details the final filter membrane material and pore size. PES stands for polyethersulfone, a membrane material widely recognized for its high flow rates and low protein binding characteristics, making it ideal for biopharmaceutical applications. The 0.2 µm pore size is the industry standard for sterile filtration, ensuring the efficient removal of bacteria and other microorganisms from the liquid.

This Sartorius filtration unit provides a two-stage filtration process: the SartoGuard prefilter removes larger particles, and the SartoPure PES 0.2 µm membrane guarantees sterile filtrate. This combination makes it particularly well-suited for applications in the biopharmaceutical industry, where the sterile filtration of cell culture media, buffers, and other critical fluids is of paramount importance.
