A bioprocess equipment company built around real applications

bbi-biotech GmbH is a Berlin-based company specializing in bioreactors, fermenters, automation, sampling and lifecycle support for bioprocess applications.

When the process matters

More than a standard catalogue choice

Customers come to bbi-biotech when vessel configuration, automation, sampling, gas supply, documentation, service access or retrofit requirements cannot be solved by a simple standard catalogue system.

Configured around your application

Technical discussion before system definition

bbi-biotech combines technical discussion, engineering experience and configurable system concepts to help customers define equipment around their actual application – not the other way around.

From lab to production

A technical partner for controlled scale-up

From early laboratory development to pilot-scale systems, production-oriented stainless-steel projects and modernization of existing bioreactors, bbi-biotech supports customers who need a serious technical partner.

We configure bioprocess equipment around the process – not around a fixed catalogue package.


From laboratory systems to production-oriented bioprocess projects

From benchtop systems to retrofit, production systems and automated sampling, these solution areas define what bbi-biotech stands for.

Together, the leadership team reflects what customers need from a serious bioprocess equipment partner: experienced bioreactor judgement, commercial responsibility, customer-focused project scoping and engineering execution. For customers, this creates a direct advantage. Technical and commercial questions can be discussed with people who understand the process, the equipment and the decisions behind a successful project.


bbi-biotech – A legacy bioreactor brand, rebuilt for modern process automation

bbi-biotech GmbH was re-founded in Berlin in 2009, but the roots of the bbi brand reach much further back into one of the most influential chapters of professional bioreactor engineering.

A defining presence in professional bioreactor technology

In the 1990s and early 2000s, the bbi brand became a familiar reference point for many users, service engineers and process developers – shaping expectations around robust vessel design, reliable operation, serviceability and long-term support.

Legacy carried forward through modern engineering

bbi-biotech GmbH carries this legacy forward as an independent company, com­bining experienced bioreactor leadership with a new generation of automation-focused engineering.

bbi-biotech – Timeline

1987

B. Braun Biotech International GmbH – the BBI roots

The roots of today’s bbi-biotech brand go back to B. Braun Biotech International GmbH, a company founded in 1987 within the B. Braun environment in Melsungen. In the bioprocess industry, the company became widely associated with the abbreviation BBI – linked to fermenters, bioreactors, cell culture systems and controlled bioprocess equipment for laboratory and production applications.

BBI was not a marginal niche brand. B. Braun Biotech International became one of the defining suppliers in professional fermenter and bioreactor technology, with a large installed base that shaped expectations around robust vessels, reliable automation, serviceability and long-term operation for many users, service engineers and process developers.

1990s

Bioreactor experience carried by people

The connection to this legacy is not only a brand story. Two members of today’s bbi-biotech leadership team, Bernd-Ulrich Wilhelm and Norbert Metzler, have worked with bioreactor systems since the B. Braun era in the early 1990s.

Bernd-Ulrich Wilhelm worked with responsibility in sales, product strategy and bioreactor development. Norbert Metzler worked in installation, commissioning and worldwide service of bioreactor systems.

For customers, this means practical experience with real installations, real service situations, real user requirements and the long-term realities of bioprocess equipment.

2000 / 2004

From B. Braun Biotech International to Sartorius BBI Systems

In 2000, Sartorius acquired B. Braun Biotech International GmbH from B. Braun Melsungen AG. With this acquisition, BBI bioreactor technology became part of the Sartorius Group and remained closely connected with fermenters, bioreactors, cell culture systems and automation for laboratory and production applications.

On 1 March 2004, B. Braun Biotech International GmbH was officially renamed Sartorius BBI Systems GmbH. The BBI name therefore remained visible for a period, but was increasingly integrated into the Sartorius corporate and brand structure.

2009

bbi-biotech GmbH re-founded in Berlin

In 2009, bbi-biotech GmbH was re-founded in Berlin by Bernd-Ulrich Wilhelm after the bbi-biotech brand had been officially registered again for the independent company.

The new bbi-biotech was not built as a catalogue supplier. It was built around the idea that serious bioreactor systems should be configurable, serviceable and technically aligned with the customer’s process – supported by automation, sampling, engineering and direct application discussion.

xCUBIO & bioPROBE

Legacy translated into new technology

The re-founded bbi-biotech did not simply continue a familiar brand. It turned established bioreactor understanding into its own technology platform.

With xCUBIO, bbi-biotech developed its own automation environment for configurable bioreactor systems – from laboratory units to pilot systems, in-situ installations, retrofit projects and production-oriented applications.

With patented bioPROBE sampling technology, bbi-biotech added a second core competence: automated sterile sampling, controlled sample transfer and integration into broader process and analytics workflows.

Together, xCUBIO and bioPROBE show what the revived bbi brand stands for today: established bioreactor understanding translated into modern automation, sampling and process-oriented engineering.

Today

Experienced bioreactor thinking, modern automation engineering

Today, bbi-biotech combines experienced bioreactor leadership with a modern automation-focused engineering team.

This combination is especially valuable for customers who need a supplier that understands both sides of the bioreactor world: established systems with technical and economic value, and new configurable platforms built for modern process development, scale-up, production support and automated sampling.

For customers, this means continuity where it matters most: experienced people, modern automation, practical retrofit concepts and support for both new bioreactor projects and existing installations.

bbi-biotech carries forward a strong bioreactor legacy by doing what serious bioprocess projects require today: engineering configurable systems, modernizing valuable installations and developing automation and sampling technologies around real process needs.


Real systems for real bioprocess work

Project examples and real implementations show how bbi-biotech works across new bioreactor systems, retrofit projects, automated sampling and production-oriented bioprocess environments.

Automated sampling for 16 third-party bioreactors in Singapore

In a research environment, four bioPROBE quad systems were integrated with 16 bioreactors to create a more scalable, deeply connected setup.

The project included iceBLOCK as well as extended OPC UA and Lucullus connectivity for more advanced automation and data integration.

Production setup in Germany up to 7000 L for soil health application

A production-oriented project for soil health applications uses xCUBIO automation in vessels up to 7000 L culture volume .

Multiple xCUBIO control units were coordinated to create a consistent automation architecture including units for media preparation.

Cell culture production platform with sterilizable transfer line

An xCUBIO in-situ setup combining a 20 L seed reactor with a 100 L production reactor.

The system was designed around a sterilizable transfer concept between both vessels, with the transfer line integrated into the software functions and CIP, and prepared for separate sterilization.

Retrofit for a large pharmaceutical producer in China

An UD50 and an UD500 bioreactor were upgraded with xCUBIO retrofit automation, including new glucose integration and pressure control.

The project was delivered under difficult lockdown conditions in close cooperation with a local service team.
