While in the process of transferring to a new manufacturing facility, scientists and engineers at Genentech, Inc. performed small-scale studies to evaluate several candidates for a single-stage depth filter train to accommodate existing equipment at the new facility.

After testing several dual-layer, single-stage filter media, the team chose a robust filter and implemented it at commercial scale. By replacing the traditional two-stage filtration train, they were able to provide significant cost savings relative to piping reconfiguration, new equipment purchase, and new equipment validation.
