Descrição Geral

The Sedimentation Study Unit, "ESED", designed by EDIBON, allows studying and compare the sedimentation processes of several suspensions simultaneously.

It is formed by five sedimentation methacrylate cylinders mounted vertically on a panel, incorporating measuring scales appropriate lighted for easing observation.

All that, enables the simultaneous study of the behaviour of five different suspensions.

Each cylinder may be removed from the panel for the appropriate washing and conditioning.

The unit is supplied with: stopwatch, light diffuser screen, fluorescent tubes, beakers, graduated cylinder and pycnometer.

It enables to have available several amounts in suspension, in order to study the differences in the sedimentation regimens, measuring the changes in heights of the solid-liquid interfaces respect to time.
