Abstract
A system for automatically processing liquids in open-ended containers. The containers are moved past a plurality of operating stations that carry out the following operations: washing, reagent-adding, incubation, detection, and storage. The operating stations for washing and reagent-addition include vertically and horizontally movable assemblies for operating upon the containers. The containers are carried in groups in individual carrying blocks which are moved throughout the system.
Claims16
A system for automatically processing liquids in open-ended containers comprising conveyor means for conveying said containers past a plurality of operating stations, one of said operating stations comprising a station for adding and removing a liquid respectively to and from said containers, said station comprising a head assembly engageable with at least one of said containers and including at least one liquid supply tube and at least one aspirating tube, said head assembly including means for positioning only one of said tubes within the open end of one of said containers at any time.
In a system for automatically processing liquids in open-ended containers, a washing assembly for adding and removing a washing liquid respectively to and from said containers, said washing assembly comprising supply and aspirating heads positioned above said containers and movable vertically thereover, said supply head including at least one liquid supply tube communicating with a liquid supply manifold within said head, said aspirating head including at least one aspirating tube communicating with a vacuum chamber within said aspirating head, said aspirating and supply heads being movable vertically with respect to each other, said supply tube extending at an angle with respect to the vertical and terminating within said supply head, and said aspirating head being movable to move said aspirating tube to a position in which it extends through and below said supply head.
