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.

Automatic cataphoresis apparatus

A blood serum applicator means for electrophoresis comprising two thin plates each having a narrow horizontal portions supported by a vertical supporting portion or portions and arranged with a pre-determined space between each other. Blood serum is permeated into a groove formed by both narrow horizontal portions and applied to a film such as filter paper, cellulose acetate film, etc. by pushing the above narrow horizontal portions onto the film.

Blood serum applicator

An electrophoretic apparatus for use in a quantitative analysis of a specimen such as a blood serum applied to a belt-like carrier body, which is capable under the unified conditions of performing the electrophoresis for the blood serum by applying direct voltage to the latter through the carrier body and comprises a main body having a pair of buffer solution troughs respectively containing a buffer solution, a transport means for transporting the carrier body into and out of the main body, a pair of high absorbent paper at least a part of each of which is dipped into the buffer solution in respective buffer solution troughs and contacting means for contacting each side end portion of the carrier body with each one of the high absorbent paper, whereas the direct voltage is applied to the carrier body through the buffer solution and said pair of high absorbent paper.
