PS Prozesstechnik GmbH has the right membrane filtration unit for your application. We do build taylor made membrane units but over many years of experience also with our own test units we have selected 2 “standard” lab units presented here: MiniMem and MaxiMem. They differ mainly in the minimum working volume and membrane area. They are versatile in the type of process and membrane used: reverse osmosis, nanofiltration, ultrafiltration and microfiltration. All units can be used for aqueous applications as well as any organic solvent. If needed the units include stirring of the feed vessel and electronic level control for automated diafiltration or full automation of concentration and diafiltration processes. Pressure, temperature, feed flow and optionally permeate flow are electronically indicated and recorded. All units are temperature controlled. Membranes of any manufacturer can be used. We can deliver a starter package of membranes according to your appilcation.

Differences: MiniMem MaxiMem
minimum working volume 10 / 30 ml 200 ml / 3 l
feed vessel 30 / 100 ml 2.5 / 5 / 100 l
membrane area 5 / 28 cm2 0.02 / 0.3 / 2.5 m2
typical permeate flux 0.25 / 1.4 ml/min 10 / 150 / 1250 ml/min
Operating pressure of all units 1-40 bar (higher on request). We adapt the units to fulfill special requirements of your application.
