Rentschler Invests EUR 24 Million in Stainless Steel Bioreactor Manufacturing

Rentschler Biotechnologie GmbH has announced the investment of €24m to build a Twin system with two 3,000 L stainless steel bioreactors mainly targeting market supply at the company’s site in Laupheim, Germany.

The Twin system is designed for running two main bioreactors in parallel with one shared downstream processing unit thus providing higher throughput while reducing incremental labor costs involved.

It integrates well into the existing 3,000 L GMP line and will more than double the production capacities for cell culture-derived proteins. The Twin system allows us to run cell culture processes in fed-batch mode with a very high output in a single suite.

“The expansion will strengthen our global competitiveness and increase our market awareness of being a CMO partner of first choice all the way down from early clinical trials up to approval and market supply with a wide range of manufacturing technologies to offer” explains Frank Ternes, Chief Business Officer at Rentschler.

In the last few years, Rentschler has been heavily investing in single-use technology and only recently announced that it will add a new 2,000 L single-use bioreactor. Nevertheless, manufacturing in stainless steel is far from being outdated.

Rentschler is experiencing a high demand for stainless steel bioreactor capacity, mainly for market supply, but also for late clinical phases.

The criteria for bioreactor selection includes the characteristics of the product to be manufactured, the approval phase, the expected volume requirements, the required flexibility, and competitive pricing due to optimal technological fit.
