Soil Permeability Apparatus
Product Code : LSK-SM-10661
Soil Permeability Apparatus (SKU LSK-SM-10661) is a gun metal permeameter mould with a set of glass standpipes for measuring how quickly water flows through a soil sample. It is used in soil mechanics practicals for B.Tech and diploma civil engineering and in TVET construction materials courses. Colleges, polytechnics, training institutes, tender contractors and distributors obtain the apparatus through Science Lab Supplies in Ambala, India.
Specifications
The table lists the falling-head permeameter part by part. In short, a gun metal mould of 100 mm ID x 127 mm high (1000 ml) is closed by valved gun metal end plates holding porous stones, and three glass standpipes of about 6, 10 and 20 mm diameter, each over 1 m long, stand on a wooden board.

Applications and Experiments for the Soil Permeability Apparatus
The apparatus measures the coefficient of permeability of soil, a value engineers need for seepage, drainage and settlement calculations. Students place or compact a sample in the mould, connect a standpipe and time the fall of the water head between two marks on the scales.
- B.Tech / B.E. civil engineering: falling-head permeability test on fine-grained soils, timing the head fall with a Digital Stopwatch.
- Diploma civil engineering: comparing the permeability of sand, silt and clay samples compacted with the Automatic Mechanical Soil Compactor.
- TVET construction materials and road works modules: drainage behaviour of fill and subgrade soils.
Standard Scope of Supply
Each set includes one each of the gun metal mould, extension collar, dummy plate (false bottom for compaction), drainage base plate and drainage cap, plus two porous stones, a metallic clamping ring, the three standpipes on a wooden board with two metre scales, and 3 m of rubber tubing with pinch cock.
Packing, MOQ and Lead Time
Quotations can cover a single permeameter or enough sets for a whole practical batch, and each one lists packing, delivery time and price for the quantity requested. A compactor or bench oven for sample preparation can be added, useful when buying TVET workshop equipment for a new lab.
Holding an Importer-Exporter Code as a registered exporter, Science Lab Supplies can ship to buyers in Rwanda, South Africa, Qatar, Sri Lanka, Vietnam and Malaysia. Questions on standpipe sizes can be raised on the contact page, the apparatus can be saved to the enquiry cart with other soil items, and institutional tenders are handled via the lab tender page.
Frequently Asked Questions
What test is the Soil Permeability Apparatus used for?
It determines the coefficient of permeability of soil. With the standpipes it runs a falling-head test, in which the drop in water level over a timed interval gives the flow through the sample.
Why are there three standpipes?
Tubes of about 6, 10 and 20 mm diameter let you match the tube to the soil: a narrow tube gives a readable fall through low-permeability clays, while a wider one suits more permeable soils.
Who supplies this apparatus?
Science Lab Supplies supplies the permeameter from Ambala in India and prepares the quotation itself for engineering colleges, polytechnics, training centres, contractors and distributors, naming each part of the set.
What is the dummy plate for?
It acts as a false bottom while soil is compacted in the mould. For the test itself it is replaced by the drainage base plate with its porous stone.
