Filtration

Filtration

We offer a number of options for the sterile filtration of aqueous solutions (e.g. cell culture media). The range includes filtration units for various volumes from 1 ml up to 10 l. The filter membranes are available with different pore sizes and can therefore be used for a wide range of applications. The Filtropur product range is characterised by its variability, cost efficiency and rapidity.

    What are the characteristics of Filtropur S, Filtropur S plus and Filtropur L filters?

    The filters have a very low level of protein adsorption, they are biocompatible, non-cytotoxic and have very small dead volumes and high flow rates. Their properties make Filtropur S, Filtropur S plus and Filtropur L filters with a pore size of 0.2 µm particularly suitable for the sterilisation of aqueous solutions.
