Working principle:
Heart of the unit is a membrane module with special magnetic stirrer. All flat sheet membranes for ultrafiltration, nanofiltration and reverse osmosis can be used. Operating volume is typically 10-100ml ! This means the principle of cross flow filtration can be used for applications with very expensive substances - e.g. pharmaceuticals in early development stages. Two membrane modules can be stacked to compare two membranes in the same experiment.

Complete system with stainless steel housing, integrated high pressure pump, controled feed pump for automated diafiltration or concentrating process. Electronic display and recording of temperature and pressure, membrane module with heating/cooling plate, operating vessel with level control.

CoolMem: mini heating - cooling system

Applications:

• reverse osmosis, nanofiltration, ultrafiltration
