Key features

Hydrophilic, controlled asymmetric, high-capacity MachV polyethersulfone (PES) membrane ensures maximum flow and throughput performance for smaller, more cost-effective filtration systems.
For large production volumes, scale up from Mini Kleenpak capsules to high-area AB-style cartridges and Kleenpak Nova capsule filters. These formats feature a laid-over pleat membrane construction coupled with a narrow core design for the highest flow rates and rapid fluid processing when effective time and cost control is paramount.
Bacterial titer reduction in excess of 6 log for Brevundimonas diminuta ensures low bioburden levels in filtrate, regardless of bacteria or particle loading
Broad pH compatibility for processing a wide range of buffers and other fluids
High membrane area featuring cresent-shaped laid-over pleat construction combined with a narrow diameter core guarantees high flow rates, robustness and smaller multi-cartridge assemblies
Kleenpak capsule formats eliminate housing cleaning and associated validation, for ease of use and integration into Allegro single-use disposable systems
Low-binding polyethersulfone membrane for maximum transmission of proteins
