Many investigations into soil porosity and permeability can be performed with this model.
Test the relationship between particle size and porosity, the concepts of gravitational water and usable reserve, the effect of grain size on permeability, and more.
Fill the plastic cylinder with sand and soil, then inject water into the column and watch what takes place.
Includes: cylinder, 100 ml syringe, plastic base, a mounting pin for attachment to a ring stand, sample sands filter, and user’s guide.
