Laboratory Ultrafilter

This unit enables the study of preparative chromatography and ion or molecule exchange. Pedagogical Objectives: Study of separation efficiency depending on: Transmembrane pressure (inlet/outlet retentate-side and permeate-side pressure gauges). Flow velocity across the membrane (pump outlet valve). Learn about Laboratory Ultrafilter suppliers for optimal educational outcomes.. Cutoff threshold: one 50 nm membrane standard, with 20 nm and 100 nm membranes available as options. Temperature (product temperature regulation) via hot/cold control with a 3 kW heating unit connected to the network.
