Sartorius, FFU500259, Sartopore® 2 XLG

The Sartopore® 2 XLG family offers advanced filtration solutions with an asymmetric membrane structure, ensuring high throughput and reduced costs. Designed for diverse biopharmaceutical applications, they provide reliable performance across various scales.

Sartopore® 2 XLG is a high-performance membrane filter, offering more than just reliable sterilizing-grade filtration in biopharmaceutical processes. Its highly asymmetric membrane structure and composition of 0.8µm prefilter in front of the sterilizing-grade filter (0.2 µm pore size), boosts the filtration efficiency in downstream processing of protein-based therapies or innovative drug delivery systems like lipid nanoparticles (LNPs). Thanks to the outstanding total throughput, Sartopore® 2 XLG is also a choice for filtration after the cell harvest.
Main Applications
Focus applications include:
Cell culture media preparation
Post cell harvest filtration
Protein-based therapies (Downstream intermediates, form & fill)
Lipid nanoparticles (Downstream intermediates, form & fill)
Your Benefits
Increased total throughput leads to less filter consumption, less process interruptions and reduced costs
Increased effective filtration enables the use of smaller filters to reduce footprint and waste
Proven and robust membrane chemistry known from the widely established Sartopore® 2 family lowers validation effort in case of process optimization
Broad range of formats and sizes assures scalability and enables use of Sartopore® 2 XLG along the whole drug product lifecycle: from development to commercial processes
Offers secure bacterial retention according to ASTM guidelines
The XL family
The XL in its name indicates an increased effective filtration area (EFA). Thanks to a different pleating technology, these filters offer a 30-40% larger EFA compared to conventional Sartopore® 2 filters, depending on the format. This enhancement results in greater total throughput per filter element, reducing filter consumption and allowing for smaller filter elements, thereby minimizing both footprint and waste.
Membrane
Sartopore® 2 XLG uses a heterogeneous double membrane made of polyethersulfone
Compatibility
The Sartopore® 2 XLG polyethersulfone membrane has a high chemical compatibility between pH 1 to 14, making Sartopore® 2 XLG filters ideally suited for the filtration of high and low pH solutions in pharmaceutical | Biotech Industry.
Cost savings
Utilizing disposable filter elements removes the necessity for investing in stainless steel filter housings. This approach also eliminates additional expenses associated with housing cleaning and cleaning validation.
Flexibility
Sartopore® 2 XLG filters are available in a wide range of filtration areas from 4.5 cm² up to 2.4 m² and with a variety of commonly used connections to ensure easy integration into your process regardless of batch size.
Scalability
Consistent and predictable scale-up and scale-down procedures are ensured with Sartopore® 2 XLG filter elements, as they are all crafted using the same membrane type, support fleeces, and construction materials, providing reliability across applications.
Quality
Each element undergoes integrity testing to meet stringent quality standards, ensuring reliable performance in its applications.
Microbial Retention
Sartopore® 2 XLG filter cartridges are validated as sterile filter cartridges according to HIMA and ASTM F-838-05 guidelines.
Documentation:
Sartopore® 2 XLG filters have been designed, developed and produced in accordance with the ISO 9001 certified quality management system. A validation manual is available in accordance with regulatory requirements.
