Description

The GPBUF1 bench allows the study of ultrafiltration.

The flux passing through the membrane is called permeate and the flux retained by the membrane is called retentate. This separation is made possible by the pressure difference applied between the incoming flux and the permeate flux.

The ultrafiltration occurs most often in tangential mode, it means that the flux circulates parallel to the membrane, in order to limit the accumulation of stopped species on the surface of the membrane.

The robust design of this equipment makes it perfectly suited for school use.

Its anodized aluminum structure on wheels makes it very robust as well as a great flexibility of integration into your premises.The manufacture of this equipment meets the European machine directive
