1. An apparatus for automatic application of blood serum comprising guide means, a serum applicator movable along the guide means;
- drive means for moving the applicator to a serum supply station, a serum application station and a rinsing station in sequence, said stations being arranged at closely spaced intervals and adjacent to the guide means, and a dripping device associated with the applicator and positioned adjacent to at least one of the stations, the dripping device including a paper filter for removing by absorption of rinsing water adhering to the applicator, and at least one roller disposed for contact with at least one surface of the paper filter for causing a movement thereof, said dripping device being effective to contact the applicator which has been subjected to an operation in the rinsing station by bringing a forward end of the applicator into abutment against the paper filter, said paper filter being moved by a given distance by rotating the roller for a limited time interval during the movement of the applicator through the various stations, thereby presenting a fresh portion of the paper filter for abutment by the applicator.

Abstract
An apparatus for automatic application of blood serum comprises an applicator, a rinsing unit and a drip both associated with the applicator, means for conveying a blood serum bearing film while maintaining it in opposing relationship with the applicator, and means for supplying a buffer solution for wetting the film with a buffer solution prior to the application of a blood serum thereto. Blood serum is automaticaly applied to the film which is previously wetted with the buffer solution in an automatic manner.

2. Automated apparatus for applying a measured sample of serum to a substrate for subsequent testing comprising:
-
means for applying a buffering solution to said substrate; applicator means; a serum supply station; an application station;
said supply and application stations being arranged at closely spaced intervals;means for moving the buffered substrate from said buffer applying means to said application station; guide means positioned above said stations and adapted to guide the applicator means past all of the stations; means for sequentially moving said applicator means along said guide means, which define a first linear path, to said serum supply station and said application station; means responsive to positioning of the applicator means above each station for halting the applicator means; and
means responsive to halting of the applicator means for reciprocally moving said applicator means in a direction transverse to said first linear path to sequentially enable the applicator means to pick up a measured amount of serum at the supply station and deposit said serum upon said substrate at the application station. - View Dependent Claims (3, 4, 5, 6)
