A dispersion apparatus for microgravity experiments comprises two blocks (2, 4) in face to face relationships, each having an array of wells (22, 23) for containing liquids and being relatively slidable so that the wells in one of the blocks can be brought into communication with corresponding wells in the other block. The blocks are held together by a retention mechanism which imparts a substantially constant pressure at the interface between the blocks. The retention mechanism comprises rails (24, 30) situated in grooves in the outside surfaces of the blocks and a series of coiled tension springs (26) connected to the rails. The springs, acting through the rails, apply pressure to the blocks, but impart almost no force tending to cause the blocks to slide relative to each other. The blocks are guided by guide plates (20) which cooperate with grooves in the mating faces of the blocks. An embodiment in which one of the blocks has a row of wells (23') with optical windows, utilizes a guided camera (36) to observe the interior of the wells.
