Plastic Limit Roller

The plastic limit roller saves time by producing consistent results by an easily-repeatable mechanical technique.  The unit also allows for accurate results in Atterberg Limits Testing for plastic limit of cohesive soils.

The plastic limit roller consists of rigid acrylic top and bottom roller plates, covered with sheets of SAA-9 adhesive backed absorbent paper.  The paper adds no fiber to soils samples. The soil samples roll between the movable top and fixed bottom plates until the top plate contacts the 1/8″ side rails.  This prevents further thread size reduction.

The roller includes a top plate with integral handle, bottom plate, and 50-sheet pad of adhesive paper.
