Abstract
An apparatus and method for mixing photographic emulsions is disclosed. The mixer is a truncated hollow cone having a first circumference and a second end having a second circumference. The second circumference is larger than the first circumference. The cone is attached to an end of a central shaft attached to the first end. The rotation of the shaft produces micromixing of the photographic emulsion while minimizing air entrainment.
