FIELD: construction.
SUBSTANCE: device comprises an elastic plastic reservoir of a circular design basin. The basin reservoir is arranged in the form of a transparent circular cylinder with a vertical axis folded from a sheet strong transparent film joined with connection seams. The lower base of the basin reservoir is tightly embedded into a support, preserving direction of cylinder generatrices at the embedding border. The upper base of the cylinder rests against a bracket that supports the cylinder shape. In the lower base support there is at least one pair of nozzles mounted diametrically and oppositely directed along the tangent to the base circle, and the nozzles are closed via a pipeline, and there is also a control valve for a circulating pump.
EFFECT: invention makes it possible to simplify a research process, cut its costs.
