Liquid limit devices (Casagrande)
Liquid limit devices (Casagrande) (Product Code: SLE/CE/66) are cam-operated brass cup instruments used to determine the liquid limit of fine-grained soils in soil mechanics and civil engineering laboratories. Students and testing staff use them to find the water content at which a grooved soil pat closes over 1.25 cm under 25 blows, with a built-in counter recording every drop. They are made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM among lab instruments manufacturers in India, at its own factory in Ambala.
Specifications
| Parameter | Detail |

| Cup | Brass cup held on an adjustable bracket |
| Height of fall | Cup adjustable for a fall of 1 cm |
| Mechanism | Cup raised and dropped by cam action onto a rubber base of standard hardness |
| Blow counter | Counter registers the number of blows |
| Grooving tools | One Casagrande grooving tool and one ASTM grooving tool |
| Height gauge | Height gauge block for setting the drop |
| Liquid limit definition | Water content at which soil cut by a groove of standard dimensions flows together for 1.25 cm under 25 blows |
| Soil strength at liquid limit | About 0.17 N/cm² (17 g/cm²) |
| Product code | SLE/CE/66 |
| Manufacturer | Jain Scientific Equipments Pvt Ltd (ScienceLab) — OEM |
| Country of origin | India (made in Ambala, Haryana) |
What Is the Casagrande Liquid Limit Device Used For?
Moist soil paste is spread in the brass cup, a groove is cut through it with one of the grooving tools, and the handle is turned at a steady pace so the cam lifts and drops the cup onto the rubber base. The counter tallies each blow until the two halves of the pat flow together over 1.25 cm. Repeating this at several water contents and plotting blows against moisture gives the water content at 25 blows — the liquid limit.
At that moisture the soil is just passing from a liquid to a plastic state, so the liquid limit, together with the plastic limit, is used to classify clays and silts and to anticipate their compressibility. For colleges sourcing from an engineering lab equipment manufacturer, it is one of the first soil tests students perform. Check the 1 cm drop with the gauge block before each session and keep the rubber base clean and dry.
OEM Manufacturer
Jain Scientific Equipments Private Limited, known to customers as ScienceLab, is the OEM for these Casagrande liquid limit devices, which are manufactured at its licensed factory at Saha, Ambala, Haryana, India. Soil laboratories, polytechnics, universities, dealers and importers order them straight from the factory rather than through a trader.
The manufacturer can also quote extra grooving tools or height gauge blocks when you need them — just ask us. More background is on our company profile.
Related Civil Engineering Lab Equipment
The liquid limit is one of the Atterberg limits, and these items complete the set of consistency tests:
- Plastic limit set — the lower consistency limit, needed for the plasticity index
- Shrinkage limit set — the water content below which soil stops shrinking
- Moisture Tins — oven-drying the samples taken from each trial
- Brass frame sieves — separating the fine soil fraction before mixing

Frequently Asked Questions
What is included with the Liquid limit devices (Casagrande)?
Each Casagrande liquid limit device includes a brass cup on an adjustable bracket, a cam-operated drop mechanism with rubber base, a blow counter, one Casagrande grooving tool, one ASTM grooving tool and a height gauge block for setting the fall.
How is the drop height set on the Casagrande liquid limit device?
The Casagrande liquid limit device cup is adjustable for a fall of 1 cm. Place the supplied height gauge block under the raised cup, adjust the bracket until the cup just touches it, then lock the setting before testing.
What does the liquid limit measured with the Casagrande device mean?
The liquid limit found with the Casagrande device is the water content at which a standard groove closes over 1.25 cm under 25 blows. At this point the soil passes from liquid to plastic behaviour and has a strength of about 0.17 N/cm².
Why does the Casagrande liquid limit device come with two grooving tools?
The Casagrande liquid limit device includes both a Casagrande grooving tool and an ASTM grooving tool, so your laboratory can cut the groove shape called for by the test procedure it follows.
Who manufactures the Liquid limit devices (Casagrande)?
The Liquid limit devices (Casagrande) are manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM at its own factory at Saha, Ambala, Haryana, India, and are sold factory-direct with quotations issued by the manufacturer.
Can Casagrande liquid limit devices be ordered for a full teaching lab or for export?
Yes, Casagrande liquid limit devices can be quoted in the quantity your teaching laboratory needs and shipped within India and to international markets. State the number of devices, any companion Atterberg sets and the delivery destination.
