Since 1994 Aquamarijn develops high flux, precision microfiltration membranes, “microsieve membranes“. Initially, the idea was to use silicon micromaching (in those days new technology) to improve the at that time state-of-the-art membranes. But soon we realized, that the membranes opened a whole new era of filtration applications that had not been possible before. For example: separation of cells or particles on size; low pressure filtration thereby minimizing fouling rate; a low internal membrane volume thus no protein loss during processing; an extremely smooth membrane surface that declines the anchoring of cells or fouling to it.

Also new applications came across: the membranes enabled users to generate mono-disperse droplets, either to study emulsification processes or to generate aerosols.

Since then Aquamarijn has developed more knowledge and intellectual property in many other fields, originally related to the fabrication method for the microsieve membrane. Current knowledge covers (silicon/glass) MEMS micromachining, surface chemistry and cell separation, but is not limited to the specific application area.

Our researchers are experts in their own specific but diverse fields of chemistry, electrical engineering, MEMS and physics. But they don’t refuse to look ‘over the fence’ and get that specific knowledge or technology for you that will make your design or product a success.
