Sartorius Sartopore 2 XLG Midicaps Sterile Size 8 0.2 um Pore Pack of 4 Filters

The Sartorius Sartopore 2 XLG Midicaps are high-performance, sterile, ready-to-use filter capsules designed for the pharmaceutical and biotechnology industries. This Size 8 Midicap features a unique heterogeneous double-layer membrane construction, consisting of a 0.8 micron pre-filter and a 0.2 micron final membrane. The XLG version is specifically engineered with high-capacity polyethersulfone (PES) to provide superior total throughput, making it ideal for filtering media with high particle loads, lipids, or cell culture supernatants.

Technical Performance and Design

• Double Layer Membrane: The integrated 0.8 micron pre-filter effectively protects the 0.2 micron final membrane, extending service life and preventing premature clogging in challenging fluids.
• Heterogeneous Construction: This design delivers significantly higher throughput compared to single-layer 0.2 micron filters, reducing the total number of filter changes required per batch.
• Size 8 Capacity: The Midicap Size 8 provides an effective filtration area of approximately 0.2 square meters, serving as an ideal mid-range solution for pilot-scale processing.
• Chemical Compatibility: The PES membrane is highly resistant to a broad range of chemicals and remains stable across a wide pH range.
• Sterility Assurance: These capsules are supplied pre-sterilized and are 100 percent integrity tested during manufacturing to ensure the highest quality and safety standards.

Operational Advantages

• Optimized Recovery: The modified PES membrane is designed for low non-specific protein binding, ensuring maximum recovery of valuable active ingredients.
• Ready to Use: Being self-contained and pre-sterilized, these capsules eliminate the time and labor associated with cleaning and assembling traditional filter housings.
• Scalability: The Sartopore 2 XLG line uses identical materials across all sizes, allowing for a predictable and linear scale-up from Midicaps to full-scale production cartridges.
• Reduced Contamination Risk: The fully enclosed capsule design minimizes operator exposure to the process fluid and reduces the risk of external contamination.
