Fully-automatic Total Migration Tester AUTO ZF1800G

 The AUTO ZF1800G Fully-Automatic Total Migration Tester represents a breakthrough in laboratory automation. This advanced system integrates water bath evaporation, heating, drying, cooling, and constant temperature weighing into a seamless, fully automated process that eliminates the need for manual intervention.

Designed for versatility, the AUTO ZF1800G excels in a wide range of applications, including:

Overall migration testing (non-volatile matter, evaporation residue)

Analysis of purified water, pharmaceutical packaging materials, food packaging, and cigarette tipping paper

Chemical reagent testing

Water content and loss on drying assessments for solid samples

Total dissolved solid content analysis in water quality testing

This comprehensive functionality makes the AUTO ZF1800G an indispensable tool for quality control laboratories across multiple industries.

Test Principle

The AUTO ZF1800G operates on a precise, automated principle:

The test solution is placed in the solvent storage dish of the automatic feeding system.

An empty cup undergoes cycles of heating, cooling, and weighing at a predetermined temperature.

These cycles repeat until a constant weight is achieved.

The solution is then evaporated to dryness on a water bath, maintained below the boiling point of the soaking liquid.

The testing cavity is heated to 105°C for thorough drying, followed by a cooling phase.

Once cooled, the evaporating dish is weighed using a high-sensitivity balance (0.01 mg precision).

The system automatically determines if the constant weight requirement is met, terminating the experiment when achieved.
