Sartopore® 2 XLG Capsule Size 4 | 5pc

Sartopore® 2 XLG Capsule is a sterile delivered PES membrane filter in a single-use housing and performs sterilizing-grade filtration of small volumes in bioprocesses. Its unique membrane composition boosts the filtration efficiency in downstream processing of proteins or lipid nanoparticles.

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.

The XL in its name indicates an increased effective filtration area (EFA). By using a different pleating technology, the EFAs of Sartopore ® 2 XLG filters are - depending on filter format - 30-40% higher than for the conventional Sartopore® 2 filters. This leads to higher total throughput per filter element and less filter consumption or enables the use of a smaller filter element for a process to reduce the footprint and waste.

Sartopore® 2 XLG filters are available in all established formats with different sizes and for different purposes: Conventional filter cartridges for stainless steel housings or single-use capsules like the small Capsules, the mid-sized Midicaps®, the larger Maxicaps® / T-Style Maxicaps® and the Maxicaps® MR for very large volumes (e.g, clarification after bioreactor harvest). The single-use capsules are available as pre-sterilized (by autoclaving), autoclavable or gamma irradiatable versions. The wide range of different filter formats and sizes ensures that customers can easily scale up their process during drug development process – from preclinical to commercial scale.
