Dispersions
Top
A whole range of dispersions can be run through EmulsiFlex high pressure homogenizers to reduce particle size as well as make the size distribution uniform. EmulsiFlex homogenizers are involved in the processing of dispersions such as drug dispersions, herb extracts, industrial coatings and pigments. Shown is a sample of a dry crystalline (amorphous) powder run through an EmulsiFlex homogenizer at 25000psi/173MPa. |

Liposomes prepared using the EmulsiFlex high pressure homogenizer, extruder
or both in combination. Combined homogenization yields 113.7nm in
one pass and 89.9nm in two passes.

An example of uniform, unilamellar liposomes.
Pharmaceutical
emulsion 'A' after processing at 18000psi/124MPa. Note the dramatic
reduction in size (52nm) and the narrower distribution.
