We have over 100 years combined experience in research, design, and commercial manufacture of EBA and packed chromatography columns

Core values

Biotechflow Ltd was founded in 2010, a company specialising in the original design, manufacture, installation, and validation of Expanded Bed Adsorption Chromatography (EBA) columns and accessories (as well as other novel solutions) for cGMP biopharmaceutical downstream processing.

We enable our clients to scale up from laboratory to commercial scale production of mAb’s and other therapeutic biopharmaceuticals. This is enabled by the seamless transfer of unclarified biomass directly from bioreactor into the patented single column (EBA).
