“Organic growth” business model

Development of quality DSP products for the Bio-Pharmaceutical industry requires focus, time and patience. At the start of Proxcys in 2003 this was the main reason for Marcel Raedts, current owner and CEO, to decide for the "organic growth" business model. In 2010 Proxcys moved into a new and larger facility of > 1000m2 in Nieuw-Amsterdam where clean assembly & production possibilities are created. 2011 is the start of the Pre-packed & Pre-validated columns that highly facilitate the entry and acceptance of RFC technology. 2016 Proxcys introduced the Tripod system, a column design with the smallest environmental footprint of process scale columns supporting awareness and sustainability programs.
