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. 

  • Only need to manually put evaporating dish with liquid sample in machine test chamber; evaporating, drying, weighing, repeating process, constant weight judgment, and calculation are all automatically done by system.
  • Water bath device is built-in; evaporating, drying and weighing are all done in machine chamber; this simplifies the operation procedure.
  • 8 work stations, each with independent test data; can test 8 samples at the same time.
  • Programmed, automatic temperature control.
  • LCD display test data.
  • Transparent window view, with lighting inside chamber, convenient to use.
  • The heating system is outside chamber, no high voltage electricity inside chamber, safety ensured.
  • Over temperature protection.
  • Professional software, simple interface, easy to use.
  • Real-time display weight, residue rate, temperature etc. for each work station.
  • Flexible test process setting and parameters setting for each work station.
  • Professional test report.

Working Principle 

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.
