Abstract
An instrument for quantitative analysis to measure a minute quantity of antigens or antibodies in a sample. There is a defined travel path for holding sample container holding means thereon, moving means coupled to said travel path to move a plurality of containers in a gang along said travel path, a work station including sensing means to sense a passing container in the container gang to align the containers at said work station. Probes at the work station are disposed above the containers when aligned at the work station. Lift means are provided for lowering and raising the probes into and out of the containers so as to add and remove liquid therefrom and program means control the operation of the instrument including the repetitive addition and removal of fluid from the containers whereby reagents are added to said containers, to lay down a film of immunologically active substance on walls of the containers. Liquid is then removed from the containers and the containers are washed repetitiously by successive additions and removals of a wash solution so as to leave the tubes coated with the immunologically active substance free of contaminating impurities.
