The training of students’ corresponding knowledge and skills is suitable for the practical training and assessment of relevant majors in higher vocational, high school, secondary vocational schools and technical schools. The equipment is used to study the basic physical process of sedimentation, including the formation of the zone and the hindered precipitation, so that students have a preliminary intuitive understanding of the basic physical process of precipitation. 

Features:

Five glass columns of the same size are mounted vertically on the back board to form a measurement scale.

The practical training platform adopts aluminum profile frame structure, each unit is flexible, easy to use and not easy to damage.

Use the bench base and background light to make the observation more convenient.

Each column can be easily removed from the backboard for cleaning, filling and mixing of solid particles.

Learning objectives/experiments:

Dependent on the solid density and concentration and the liquid density and viscosity

Determination and comparison of the settling velocities of solids in suspensions

Influence of coagulants on the settling velocity

Specification:

Experiments in the fundamentals of sedimentation

3 measuring cups for preparation of suspensions

Pycnometer to determine the density of the liquids and solids

Tanks backlit by fluorescent tubes to aid observation

5 transparent tanks with scale for comparison of the settling velocities of solids in various suspensions

Tanks removable for filling, mixing and cleaning

Recommended accessories: balance,coagulant

Stopwatch to record the sedimentation time.
