Evaporation Residue Tester can test the dissolving-out amount of test sample soaked in specified liquid.
Applicable to tableware, food containers, packaging films, bags, cap sealing rubber pad, painted coating for inner wall of cans or tins, plant fiber container and so on made from polyethylene, polystyrene, polypropylene, perchloroethylene resin, epoxy novolac etc.; also applicable for some chemical reagents.
Soak test sample in specified liquid; wash and evaporate evaporating dish dry, and put it into the machine chamber to dry it until its weight is constant; take an amount of the liquid and hold it in evaporating dish, evaporate the dish dry in water bath device; then put evaporating dish in machine chamber to dry in high temperature, and weigh the dish; then dry again, and weigh again, repeat this process until the weight is constant; the weight minus the weight of evaporating dish itself is the value of Evaporated Residues.
