Choosing a Merane for IVRT Studies Using PermeGear Cells

Most merane filters are circular and commonly available in 13, 25, and 47mm diameters. Some filters are avail-able as sheets. Dialysis meranes can also be used for IVRT experiments and are available as sheets or tubes. Although meranes are easily trimmed to suit one’s cell dimensions, a 25mm diameter filter is most appropriate to

How to Select the Right Merane Syringe Filter

2-in-1 filters are a two-layered filter in a single housing with a built-in glass fiber pre-filter on the top layer and a merane filter on the bottom layer. The coarse pre-filter removes the larger particulates that would plug the merane filter. This type of filter is recommended for difficult-to-filter samples.

Merane Filter - an overview | ScienceDirect Topics

The MF test is easier to perform than the MPN test because it requires fewer test tubes and less handling. Usually about 100 ml of water is passed through a merane filter (pore size 0.45 µm). This merane is then placed on a thin, absorbent pad saturated with differential or selective medium (Figure 17.2).For example, if total coliform organisms are sought, a modified Endo medium is used.

PTFE merane filters have an excellent chemical compatibility (pH 1 to 14), so that they are also used for the filtration of solvents and acids, to which other filter types are not resistant. Moreover they can be used to filter aqueous solutions as well, but because of their hydrophobic characteristics, they must be pre-wetted with ethanol or

Pore Sizes and Volumes. The filter size depends highly on the filtration volume. For small volumes (< 1 ml), syringe filters with a diameter of 3 mm are used for medium volumes (1-10 ml), 15 mm and for large volumes (> 10 ml) 25 mm. Common pore sizes for UHPLC and HPLC columns with small particle sizes (< 3 µm) are 0.2 and for columns with larger particle sizes (> 3.5 µm) 0.45 µm, respectively.
