Single-use Continuous Bioreactor for Virus Particles


Next-generation bioreactor for fast scale-up of cell-based vaccines and gene therapies

ContiVir30 is a bioreactor that enables production of virus particles at the 1–100 L scale without increasing vessel size as a traditional batch process would require. This unique advantage is possible because ContiVir30 operates in continuous mode at a production rate of 30 liter/month using a tubular bioreactor for virus propagation.

Also, with a minor system upgrade its production capacity can reach 1000 liters or more without the need to change scaffolding.


​Our current ContiVir30 Continuous Tubular Bioreactor (CTB) system has been used successfully for the production of:

  • Influenza A virus

  • Adeno-associated virus (AAV)

  • Non-infectious coronavirus-like particles (VLP) resembling SARS-CoV-2

In addition, our ContiVir30 can be used for production of other viruses such as Adenovirus, Modified Vaccinia Ankara, Yellow Fever or Coronavirus as long as a suspension cell line is available (for example, suspension HEK293, MDCK, Vero or BHK cells).

A list of four good reasons to try ContiVir30 for production of your new virus strain:

  • Stability. Does not accumulate defective interfering particles and thus provides stable virus titers.

  • Reduced mutation risk. It allows a defined residence time and thus avoids virus mutations.

  • Throughput. It is twice as fast as batch due to its increased virus production rate.

  • Flexibility. Its single-use design minimizes downtime. 

Other advantages arise if a new manufacturing process is established for a vaccine or gene therapy based on ContiVir30: elimination of the bioreactor seed train, acceleration of the R&D process, reduction of sizes of downstream units, possibility of microfactory design and reduced capital investment.
