Abstract
A coloring-decoloring apparatus for electrophoretic system comprising a bonding drum, a support plate, two rollers arranged in contact with the outer circumference of said bonding drum and a liqued trough. Said coloring-decoloring apparatus functions to color and decolor a sample carrier with coloring or decoloring liquid agent while holding said sample carrier onto said bonding drum with said two rollers and rotating said drum, and has a circumferential section which is lower in curvature than the imaginary circular circumference of said bonding drum and serves to prevent said sample carrier from being deformed or torn due to contraction even when said sample carrier is dried while being held onto said bonding drum.
