Plastic Limit Roller
Product Code : LSK-SM-10664
Plastic Limit Roller (SKU LSK-SM-10664) is a hand device for the plastic limit test that rolls a soil thread mechanically between two plates instead of by palm on glass. It gives students a more consistent thread in Atterberg limits practicals at B.Tech, diploma and TVET level. Science Lab Supplies provides it from Ambala, India to engineering colleges, training institutes, tender contractors and distributors.
Specifications
The roller has top and bottom acrylic plates separated by 3.2 mm (1/8 in) side rails, with an integral handle on the top plate. Adhesive-backed absorbent paper lines the plates and adds no fibre to the soil; a 50-sheet pad of this paper and instructions come with it.

Applications and Experiments for the Plastic Limit Roller
The roller is used to find the plastic limit, the water content at which a soil thread starts to crumble. Rolling between fixed rails sets the thread thickness, so the end point depends less on hand technique, which helps when a whole class tests the same soil.
- B.Tech / B.E. civil engineering: plastic limit and plasticity index for soil classification.
- Diploma civil engineering: Atterberg limits practicals on clays and silts.
- TVET construction materials modules: judging the workability of clay soils for fill and embankments.
Standard Scope of Supply
Each roller is supplied with its top and bottom plates, side rails and top-plate handle, a 50-sheet pad of adhesive absorbent paper and a set of instructions. Moisture tins and a drying oven for the crumbled threads are not part of the listed contents.
Packing, MOQ and Lead Time
Tell us whether you need one roller or one for every bench; the quotation will state packing, delivery time and price for that number. A plastic limit set or liquid limit device can be added, keeping workshop tools for technical training institutes on one order.

Frequently Asked Questions
How does the roller differ from rolling by hand?
Hand rolling on a glass plate relies on the operator judging the thread diameter. The roller's 3.2 mm rails set the thread thickness mechanically, so results depend less on technique.
What is the adhesive paper for?
The absorbent paper is fixed to the plates, draws moisture from the thread as it is rolled and adds no fibre to the soil. A 50-sheet pad comes with the roller.
Who supplies the Plastic Limit Roller?
It is supplied by Science Lab Supplies from Ambala, India, directly to colleges, polytechnics, TVET centres, contractors and distributors.
Can it be bought with the other Atterberg limit tests?
Yes. The Plastic Limit Set, liquid limit devices and Shrinkage Limit Set can go on one quotation for a complete limits bench.
Related Plasticity Test Equipment
The plastic limit is combined with the liquid limit to give the plasticity index, so these four Soil Mechanics items pair naturally with the roller: a manual plastic limit kit, two liquid limit devices and the shrinkage limit test.
- Plastic Limit Set — rod and glass plate kit for the hand method.
- Cone Penetrometer — liquid limit by cone penetration.
- Hand Operated Casagrande Equipment — liquid limit by the cup method.
- Shrinkage Limit Set — shrinkage limit of the same soil.
