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. Science Lab Supplies supplies the apparatus from Ambala, India to colleges, polytechnics, training institutes, tender contractors and distributors.
Specifications
The gun metal mould is 100 mm ID x 127 mm high (1000 ml), closed by a drainage base plate with outlet valve and a drainage cap with inlet and air release valves. Three glass standpipes of about 6, 10 and 20 mm diameter, each over 1 m long, are mounted 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.
- Diploma civil engineering: comparing the permeability of sand, silt and clay samples.
- 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 sieve set 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. Send questions via the contact page, collect items in the enquiry cart, or see the lab tender page for institutional tenders.
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 it from Ambala, India, quoting directly to engineering colleges, polytechnics, training centres, contractors and distributors.
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.
