Mass transfer characteristics of VMF Protein UF

Article about the mass-transfer characteristics of VMF protein ultrafiltration

VMF technology delivers a step change in protein ultrafiltration performance. It enables higher productivity, lower operating pressure and improved process robustness in bioprocessing, particularly for the concentration of monoclonal antibodies (mAbs) and other high‑value protein products.

Single-Pass VMF of mAbs

Factsheet about single-step filtration of mAbs using VMF

Single-pass VMF outperforms conventional single-pass TFF in the concentration of mAbs, with minimal fouling, high concentration and conversion efficiency and gentle, stable operation.

API/Protein Concentration & Recovery

Bioprocess diagram showing API/protein recovery and concentration using Vibro® Membrane Filtration (VMF).

In the following example, the Vibro® Technology is applied in an extracellular API/protein process where the fermentation broth is processed directly, and a concentrated API/protein is achieved. Description: The fermentation broth is processed in a Vibro-I microfiltration unit where the cells are separated…

Algae Harvest & Concentration

Bioprocess diagram showing continuous algae harvest and concentration using Vibro® Membrane Filtration (VMF).

Vibro® Membrane Filtration (VMF) enables the continuous and highly efficient harvest and concentration of algae. Within just a three steps, concentrations of 200 g/l from a constant stream of 6500 l/h can be reached. A similar process can be used to…

Beer Brewing
