array of filtration slots Micropore Technology produces filtration media that passes straight through, from one side of the filter to the other. Our filtration media does not rely on depth filtration mechanisms to remove particles, it really does sieve suspended solids, and drops, from a fluid. The picture shows an example of our slotted filter media, where we can provide media with slot widths of as low as 2 microns. For filtration to sizes less than this, we can supply an alternative media, pr a system using a slotted filter followed by a polishing filter.

Many different types of filter geometry are possible, but the filter tube is the most common and it is possible to provide surface finishes, such as gold - as shown on the home page.

One interesting application of the filters due to this true surface filtering effect is the ability of them to fractionate particles in to different sizes. This has been successfully achieved with particles down to 2 microns - well beyond the range of conventional sieves.

circular pore microfiltration array

Circular pores are available with diameters of 2 microns, or more. The pores are uniform and in a regular array

This is the conventional type of microfiltration membrane, with a tortuous pore flow channel. We do not normally recommend them for applications where a suitable surface filter is available, but we can supply sintered ceramic filters with equivalent pore sizes of down to below 1 micron.

The sintered ceramic membrane filters are completely interchangeable with the slotted membranes on the VibraFilter platform.
