A reagent pack for keeping fluids with or without suspensions mixed or suspended upon rocking. The reagent pack has at least one chamber divided into separate sub-chambers with a throat region between them defined by baffles for agitation of suspended reagent during rocking of the reagent pack. A continuous lid sealable to the pack has membrane sealed apertures in the lid for allowing access to the underlying chambers and sub-chambers by withdrawal needles. A tray is configured to hold multiple side-by-side reagent packs on respective slides that slide in and out for insertion and withdrawal of the packs. During operation, the tray and associated packs are rocked such as by being periodically inclined with respect to horizontal, providing reagent agitation. Optical annunciators proximate the tray indicate respective reagent pack activity under control of a computer which stores information on the contents of each pack at each tray location and correlates it to scheduled reagent use in a medical testing system. The tray is provided with a thermally conductive hinge. The tray with packs is located in an enclosure.

[ What is claimed is:] [1.] A reagent handling system comprising plural reagent packs, each reagent pack comprising:plural chambers formed by opposing and parallel end walls, opposing and parallel side walls substantially orthogonal to said end walls, a floor surface attached to said end and side walls proximate a lower edge thereof, and at least one intermediate wall substantially parallel to said end walls and disposed between said side walls, wherein said end, side and intermediate walls define a pack upper edge; andmixing baffles disposed within at least one of said chambers operative to cause mixing of said fluids within said at least one chamber as fluid i s passed by said baffles, a first one of said baffles disposed opposing and proximate a second one of said baffles such that a throat region having a pair of converging then diverging walls is defined between said first one and said second one of said baffles.
