ABSTRACT:
Determination of "dry rubber content" (DRC) within a latex solution. Particularly, a volumetric analysis device, including an elongated chamber with a removable filter cap positioned at one end. A compression plunger is mounted within the chamber upon one end of an axially reciprocable shaft. A compression handle and dial drum scale are mounted at that other end of the shaft, which extends through the chamber end wall. A liquid flocculating agent is mixed with a measured volume of latex solution within the chamber, then compressed by actuating the plunger. During compression, the liquid residue is urged through the filter cap. The remaining batch of precipitated latex is measured as the "dry rubber content", accordingly as the exterior dial drum intersects a reference scale on the cylinder interior.
