Evaporated Residues Tester

This instrument tests the dissolving-out amount of test sample soaked in specified liquid. Applicable to tableware, food container, packaging film, cap sealing rubber pad, painted coating for inner wall of cans, plant fiber container and so on made from polyethylene, polystyrene, polypropylene, perchloroethylene resin, epoxy novolac etc.; also applicable to some chemical reagents.

Working Principle
After test sample soaked in specified liquid, hold an amount of the liquid in evaporating dish, evaporate and dry the dish in high temperature, then weigh the dish; then dry again, and weigh again, repeat this process until the weight is constant; calculate Evaporated Residues according to the measured weight minus the weight of evaporating dish itself. Unit is mg/L (for soaking liquid) or % (for chemical reagent).

Standards
GB/T 5009.60-2003, GB/T 5009.64-2003, GB/T 5009.68-2003, GB/T 5009.69-2008, GB/T 5009.203-2003, GB/T 9740-2008

Features

• 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.
• 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.
