Tripod filtering and filtration kit

MACHINE TRANSLATION (not authorised yet)

The set consists of a quadruple wooden funnel holder mounted (adjustable in height) on a tripod bar and 4 funnels. It allows you to demonstrate the effects of filtering water and other liquids through various materials (e.g. sand, gravel, coal, paper siftings), as well as to demonstrate the properties of different types of soils (permeability, filtration capacity, water capacity). A funnel holder (4) for a tripod can be purchased as a second level of filtration.
