ABSTRACT:
An apparatus for automatic cataphoresis comprises means for feeding a blood serum bearing film; a cutter for cutting the film to a given length; means for supplying a buffer solution for wetting the film with a buffer solution; a blood serum applicator including a serum application member, a serum dish assembly, an abutment, a rinsing vessel, a drip mechanism and means for carrying the film; a cataphoresis compartment for forming fractionated patterns of the serum applied to the film; dyeing, decolorizing and drying stations for dyeing, decolorizing and drying the serum bearing film as it is delivered from the cataphoresis compartment; and a densitometer including a vessel of a clearing liquid, a light source and a detector for effecting a colorimetric determination of the serum specimen. In this manner, a determination of a blood serum is automatically achieved by the cataphoretic process.
