  • Patent number: 10272044
    Abstract: The apparatus and methods of the present invention are of use for the production of emulsion-based microparticles containing a biological or chemical agent. In particular, the apparatus provides a vessel; packing material situated inside such vessel and may further provide material capable of insertion into both ends of said vessel for enclosure of the packing material. In a particular embodiment, the apparatus is a packed bed apparatus. The methods include production of emulsion based microparticles containing a biological or chemical agent. The usefulness of the present invention is that the apparatus and methods of the present invention provide for a low-shear, non-turbulent, production of emulsion-based microparticles that provides a narrow, reproducible, particle size distribution, capable of use with both large and small volumes that is capable of being conveniently scaled up while providing predictable emulsion properties.

  • Publication number: 20070207211
    Abstract: The apparatus, methods and compositions of the present invention are of use for the production of emulsion-based microparticles containing a biological or chemical agent. The apparatus and methods of the present invention provide for a low-shear, non-turbulent, production of emulsion-based microparticles that provides a narrow, reproducible, particle size distribution, capable of use with both large and small volumes that is conveniently scaled up while providing predictable emulsion properties. The methods include production of emulsion-based microparticles containing a biological or chemical agent which, when suspended in a diluent, are syringable through a needle without clumping of the microparticles or clogging of the needle.
