An apparatus and method for the automated preparation of treated monolayers of sample material, comprising: a centrifuge having a rotor ( 12 ) carrying removable chamber blocks ( 14 ); sample and reagent dispensers ( 26 ) and control systems ( 20 ). First, centrifugal force sediments sample material discretely to form a monolayer onto a receiving surface member ( 32 ) on one of the chamber blocks ( 14 ), while the same centrifugal force opens a valve ( 48 ) in the chamber block ( 14 ) to drain sample material. Then, centrifugal force delivers sequentially into discrete chamber blocks ( 14 ) discrete treating agents, during which time the sampler material monolayer is held in place on the receiving surface member ( 32 ) by centrifugal force. Then, each chamber block ( 14 ) is drained centrifugally through its already opened valve ( 48 ). Each treated sampler material is confined to an individual chamber block ( 14 ). Batch and random access delivery of treating agents can be employed. Each chamber block ( 14 ) includes separate inlets for the sample and treating agents.
