LifeASSURE™ PDA Series Filters — The Preferred Membrane For Biopharmaceutical Applications
In addition to sterile filtration prior to the final filling step, sterilizing filters are used in many intermediate steps to reduce cross-contamination risk from in-process liquids such as buffers. Since biopharmaceutical unit operations are discontinuous in nature, elution pools (e.g. Protein A pool) need to be filtered with 0.2 µm filters prior to storage in order to manage bioburden loads. To prevent growth of microorganisms in downstream chromatography steps, post depth filter permeate is filtered using 0.2 µm sterilizing or bioburden reduction grade filters.
