SEPROSYS was created in 2009 by Stanislas Baudouin and Delphine Dufour. The company's main activity is to offer innovative solutions for basic and molecular purifications. Using tools such as tangential filtration, preparation chromatography and chemical or enzymatic catalysis, we develop processes applied by the chemical, pharmaceutical and agri-food industries. 

Pilot Plants operation

Each unit is defined jointly with the customer, to adjust the design to the specific needs of each application.


icône mise en œuvre

Pilot plant rental and On-site operation

In the fields of ion exchange, chromatography, adsorption, ultra/microfiltration, reverse osmosis and nanofiltration for the processing of a few hundred litres of product per day. These pilot tests allow to produce in semi-industrial conditions representative batches, to validate the sizing for industrial extrapolations.

Please consult us for pilot plant availability
