Shirasu Porous Glass technique

K. Kandori, K. Kishi, and T. Ishikawa Preparation of Monodispersed W/O Emulsions by Shirasu-Porous-Glass Filter Emulsification Technique. Colloid Surfaces 55, 73 (1991). 

Membrane emulsification techniques allow preparation of highly monodisperse microgel particles. The Shirasu porous glass (SPG) membrane with a pore size of 0.1-18pm was used to prepare uniformly sized water droplets containing chitosan in organic solvent, and polymer chains were crosslinked by glutaraldehyde [26],...
