Sedimentation Studies Apparatus
Product Code : LSK-TWL-10805
Sedimentation Studies Apparatus (SKU LSK-TWL-10805) is a batch settling set-up with five borosilicate glass graduated cylinders for studying how solid particles separate from a liquid under gravity. Students follow the interfaces between settling zones over time to understand zone and hindered settling. It is used in mechanical operations labs of chemical and environmental engineering courses. Science Lab Supplies manufactures the apparatus at its factory at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and sells it direct to colleges, tender contractors and distributors.
Specifications
The table below gives the complete specification of the five-cylinder sedimentation apparatus. In short, five removable borosilicate glass graduated cylinders let slurries of different concentration or particle type settle side by side, while students time the fall of each liquid-solid interface with a stopwatch.

Applications and Experiments for the Sedimentation Studies Apparatus
The apparatus is used to plot batch settling curves: as time passes, the clear liquid zone A and sludge zone D grow until all solids reach D, the critical point, after which the sludge compresses under its own weight. Comparing cylinders shows how concentration and particle properties change the settling rate.
- B.Tech/B.E. chemical engineering mechanical operations: batch sedimentation curve, compared with separation on the Equipment for Vacuum Filtration.
- Free versus hindered settling and the effect of slurry concentration.
- Terminal velocity, drag and buoyancy on a settling particle, linked to the falling-sphere tests on the Viscosity and Particle Drag apparatus.
- Environmental engineering: settling behaviour relevant to clarifier and thickener design.
Standard Scope of Supply
Each set comprises the five removable borosilicate glass graduated cylinders arranged for side-by-side settling tests. The stopwatch, the solids for preparing slurries and other consumables are not part of the standard set, so these are arranged by the laboratory or can be added to the quotation on request.

Each quotation from Science Lab Supplies sets out the packing, delivery time and price for that quantity, and other mechanical operations trainers can be quoted together when you are buying engineering lab equipment in India.
As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Ethiopia, Tanzania, Uganda, the UAE, Saudi Arabia and Oman. Enquire through the contact page or the enquiry cart, or see the lab tender page.
Frequently Asked Questions
How many cylinders does the Sedimentation Studies Apparatus have?
It has five borosilicate glass graduated cylinders, so students can compare five slurries of different concentration or particle type at the same time and plot their settling curves together.
What is the difference between free and hindered settling?
In free settling each particle moves without interference from others. In hindered settling many particles interfere with each other and the settling rate falls; most slurries settle under hindered conditions.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the manufacturer. This apparatus is built at its own factory in Saha, Ambala, India, and quotations come directly from the factory.
Are the cylinders easy to clean?
Yes. The cylinders can be removed easily for cleaning, which helps when student groups change slurries between practical sessions and need clear glass for accurate interface readings.
