Not every Sartorius Sartopore 2 XLI configuration has an exact Ultrafilter match. Our filtration experts review your part number and application and recommend the right replacement.
What it is: Biotech-optimized variant — 0.35µm + 0.2µm double-layer construction. The tighter 0.35µm prefilter gives better protection against the specific particulate load found in cell culture media, monoclonal antibody solutions, and downstream intermediates. Validated per HIMA + ASTM F-838-05.
Use for: Cell culture media filtration where colloids and protein aggregates are the dominant fouling mode. Buffer filtration for biotech processes. mAb production downstream intermediates.
