MiniMem - Model 20-2000ml - Membrane Filtration Unit
From Membrane Technology- Lab-Pilot Membrane Filtration Units - Membrane Lab Units
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, not only for aqueous systems but also for organic solvents (OSN). Minimal operating volume is 10-30ml ! This means the principle of cross flow filtration can be used for applications with very expensive substances - e.g. pharmaceuticals in early development stages - . Or simply for any application without waste of big amounts of test material. The ratio of membrane area to minimal working volume is high. This allows high concentration factors and efficient diafiltration. Two membrane modules can be stacked to compare two membranes in the same experiment. We also can supply now a bigger 120cm2 membrane module: At a typical flux of 30l/m2h this means e.g. concentrating 1000ml to 50ml in less than 3h followed by a diafiltration of factor 6 in one hour.
