Full-Automatic Overall Migration Tester

Introduction

Full-Automatic Overall Migration Tester AUTO ZF1200 has an integrated system design of water bath evaporation, heating and drying, drying and cooling, and constant temperature weighing. The test process is fully automated without manual participation. It is suitable for testing the total migration (non-volatile matter, evaporation residue) and other items in the fields of purified water, pharmaceutical packaging materials, food packaging, cigarette tipping paper and chemical reagents. It can also be applied to the water content, loss on drying and other items of solid samples, and the total dissolved solids content test in water quality testing.

Test principle

Put the solution to be tested into the solvent storage dish of the automatic feeding system. The evaporation cup in the test chamber is heated according to the set temperature, cooled, and weighed, and the steps are repeated until the constant weight value is reached. Add the solution to be tested into the evaporating cup, heat and evaporate in a water bath, heat the cavity to 105°C for drying, and cool down. After the evaporating dish is cooled, use a balance (sensitivity: 0.01mg) to judge the constant weight, and the experiment is terminated if the constant weight requirement of the project is met.

Specification

Features

Cold and hot dual-chamber integrated control system, automatic upgrade

It has an integrated system design of water bath evaporation, drying, cooling, constant weight, and reagent recovery, which can effectively avoid the influence of the external environment on the experiment, and the test is automated, efficient, and precise.

The cavity has a built-in water bath, which can automatically detect the water level through the liquid level sensor, automatically add water, replenish water and drain, and automatically control the temperature of the water bath. Multiple safety designs ensure the safe treatment of water temperature, water bath water and waste liquid discharge in an all-round way.

Temperature control: International advanced electromagnetic temperature control technology is adopted to automatically control the temperature rise and fall, and the temperature control accuracy is 0.5°C.

High-precision imported balance, isolation protection design

A high-precision imported balance is built in the chamber, with high weighing efficiency, the balance resolution reaches 0.01 mg, and the 2-round drying process can reach a constant weight of 0.3 mg.

The balance is placed in a fixed and stable protective cover with a water circulation compartment. When performing evaporation and drying steps, the balance is completely isolated from the test chamber, and when performing weighing, the temperature and humidity are stable. The weighing data is stable and reliable, with good repeatability.
