Hand Operated Casagrande Equipment
Product Code : LSK-SM-10650
Hand Operated Casagrande Equipment (SKU LSK-SM-10650), the classic liquid limit device, finds the water content at which a soil changes from plastic to liquid behaviour. A groove cut in a soil pat in a brass cup is closed by repeated drops, turned by hand and counted. Civil engineering students in colleges, polytechnics and TVET institutes use it in soil classification practicals. Science Lab Supplies supplies the device from Ambala, India to institutes, colleges, tender contractors and distributors.
Specifications
A brass cup hangs from a carriage that controls its fall to a drop of exactly 1 cm onto a hard rubber base. The drop height is adjusted with a nut at the rear of the cup, a counter records the blows as the device is turned by hand, and rubber feet isolate the base from the bench.

Applications and Experiments for the Casagrande Equipment
The device determines the liquid limit, one of the Atterberg limits which, with the plastic limit, gives the plasticity index used to classify fine-grained soils. It is a routine practical in soil mechanics and geotechnical courses and in labs testing soils for roads and foundations.
- B.E./B.Tech civil engineering: liquid limit by the Casagrande method, plotting the flow curve.
- Diploma civil engineering: Atterberg limits and plasticity index practicals.
- TVET civil engineering technician modules: soil classification for construction.
Check and reset the drop with the rear nut before each session, and keep the cup and rubber base clean and dry so that every blow is consistent.
Standard Scope of Supply
The device comes with its brass cup and carriage, the hard rubber base on rubber feet, the hand-operated drive with counter, and a Casagrande grooving tool. Mixing dishes, spatulas and moisture tins, which the test also uses, can be added to the same quotation if needed.
Packing, MOQ and Lead Time
One device or a class quantity can be quoted, and the quotation states packing, delivery time and price for that number. As a TVET lab equipment supplier, Science Lab Supplies can put the plastic limit and shrinkage limit items for a full Atterberg bench on the same quotation.
Science Lab Supplies, a registered exporter with an Importer-Exporter Code, can ship to buyers in Ghana, Ethiopia, Tanzania, Uganda, the UAE and Saudi Arabia. Send questions and quantities through the contact page, or use the enquiry cart and the lab tender page for item lists and tender buying.
Frequently Asked Questions
What does the Casagrande equipment measure?
The liquid limit of soil: the water content at which a groove cut in the soil pat closes after a set number of cup drops. Combined with the plastic limit it gives the plasticity index.
How is the height of drop set?
The carriage lets the brass cup fall 1 cm onto the hard rubber base. The height is adjusted with the nut at the rear of the cup and should be checked before testing.
Is there a motorised version?
Yes. This model is turned by hand with a counter recording the drops; a motorised liquid limit device is listed separately for labs that prefer a motor drive.
Who supplies the Hand Operated Casagrande Equipment?
It comes from Science Lab Supplies in Ambala, India, which quotes it directly to colleges, training institutes, contractors and distributors.
