The Hampden Model H-6520 Infiltration Demonstrator investigates the infiltration rates of different soil types and soil surface treatments (shown with accessories).
The Hampden Model H-6160 Solid-To-Liquid Extraction Demonstrator permits student study of the fundamentals of a solid/liquid extraction system. The student is able to determine the operating characteristics of solvent extraction from a packed bed. The equipment is constructed out of stainless steel and glass for material compatibility. Furthermore, glass parts are used where observation of the process is informative. The corrosion resistant nature of the equipment allows the unit to be used with a wide variety of systems including: water/inorganic salts; water/sugar beets; methylene chloride/vegetable oil; water/coffee and others. All experiments use non-flammable solvents.

The Hampden Model H-6150 Liquid-To-Liquid Extraction Demonstrator has been developed to permit student study of the fundamentals of a liquid-to-liquid extraction system. In addition to demonstrating the hydrodynamics of liquid-to-liquid extraction systems and interface control techniques, this unit can also be used to determine the mass transfer rates, heat transfer coefficients, extraction efficiency, and operating conditions at different liquid flow rates. The extraction process can be operated in a continuous or semi-continuous mode.

The Hampden Model H-6526 Ground Water Flow Tank provides a means of investigating simple three dimensional flow models utilizing sand as a medium. A multitube manometer is used to show profile and make level measurements at appropriate locations. Tank demonstrations provide the student with practical experiments about land drainage, flood risk, wells, and drainage of lakes or ponds.
The Hampden Model H-6523A Sediment Transport Demonstrator investigates suspended sediment in a moving stream and bed load movement. The moving stream can be controlled over a wide range to simulate fast flowing streams or slow moving rivers, demonstrating the various size and density of partial deposits. Slope is adjustable from 0-10%.
The Hampden Model H-6527 Sedimentation Study Trainer has been developed to investigate the physical processes of sedimentation. The student will be able to evaluate and measure the particles as to height, size and settling rates for making up the sedimentation curve.
The Hampden Model H-6510 Drainage and Seepage Tank Demonstrator has been developed to investigate water flow through permeable media. Using sand as the medium and two-dimensional models, flow lines can be determined as well as the distribution of up-lift pressure and seepage rates.
