Our Bioreactors

5L single-use bioreactor

Our modular bioreactors are designed to be easily scaled up or down.

Culture’s 5L pilot-scale bioreactors are designed for key stages of bioprocess development, including mammalian cell culture scale-up, microbial fermentation, and viral vector process development. These bioreactors are highly versatile, supporting media development and enabling efficient transitions to large-batch production and preclinical bioprocessing.

With broad applications across process development, process optimization, and process characterization, our bioreactors offer the scalability and reliability necessary for teams aiming to optimize their workflows and prepare for industrial-scale production. Whether you're scaling microbial fermentation or refining mammalian cell culture processes, Culture’s bioreactors provide a dependable solution.
