Accelerating Therapies from Start to Scale.

We started PBS Biotech because cell therapy was clearly going to move from a handful of academic successes to medicines manufactured at scale. The bioreactors the industry had were built for a different problem — stirred tanks were designed for microbes and proteins, not for living cells that bruise. Scaling a cell therapy meant changing the very thing you were trying to keep constant.

The Vertical-Wheel® platform is designed around a single requirement: the environment a cell experiences should not change when the volume does. That has to work in both directions — scale up from 0.1 L to 80 L, and scale down from a commercial process to a benchtop model that genuinely predicts it. Same geometry, same energy dissipation, same result. Five systems, one continuous platform.

Our customers told us the hardware was only half the problem. Cell therapy is still a young field: there is no settled playbook, few standard protocols, and process knowledge is scarce and hard-won. So our application scientists run feasibility, optimization and tech transfer alongside your team — and we publish what we learn, so the whole field moves faster.
