Emulsions

Micropore Technologies can provide equipment for the production of emulsions and dispersions from small-scale laboratory tests through to industrial batch sizes in the tonnes, we are also happy to conduct contract research in our laboratories for clients.

By injecting a dispersing phase through our novel media it is possible to generate an emulsion. The regular array of circular pores and the straight through nature of the media mean that very carefully controlled, and monosized, drop sizes can be achieved and the pressure required is much less than for the alternative sintered microfilter process.

Equipment to generate these emulsions includes: crossflow filtration tubes, using the gold plated tubes shown on the header image (top left), flat sheet membranes and tubes that are rotated to provide the shear field. In all of these systems the drop size depends primarily on the surface chemistry, disperse phase injection rate and imposed shear field. These conditions can be controlled in order to provide an engineered drop size and size distribution. Encapsulated drops are also easily possible, as the dispersion media does not destroy the primary emulsion during the injection process. Other applications include a preliminary stage before chemical reaction, or solidification, prior to forming a solid particle.

If you wish to see how our media is different from that of other microfiltration companies, please see here. This explains the true meaning of pore size in filters.
