A New Nonvolatile Residue Testing Machine for Ultrapure Water Launched

Fully Automatic, High Precise, High Efficient

C840 Integrated Evaporation Residue Testing System is a new fully automatic device developed and released by Labthink. Using the gravimetric method, this device is suitable for determinations of non-valite matter of pharmaceutical packaging and purified water, total migration of food contact materials and evaporation residue of chemical reagents .

Our Integrated Evaporation Residual Testing System provides an opportunity to:
1. residues after evaporation Determination of various chemical reagent
2. total migration amount determination of food contacting materials
3. non-volatile matters determination of purified water & pharmaceutical packaging

Why Labthink Integrated Evaporation Residual Testing System
1. Efficiency: Equipped with Fully automatic gripper, 25 test glasses.
2. Austomatic: Water bath evaporation, drying, cooling and weighing at room temperature are completed automatically.
3. Precise: Equipped with high-precision balance （0.05mg repeatability)
4. Safe：Fully-closed, zero leakage water bath

How does our Integrated Evaporation Residual Testing System works?
Total Migration
Soak the sample in a solution simulating specific food types. After evaporation and drying, the total migration of non-volatile substances is measured.

Non-volatile Matter
Soak the sample in a solution per standard requirements. Following evaporation of both test and blank solutions, the non-volatile residue weight is determined by comparison with the blank.

Test methods of our Integrated Evaporation residual testing system refers to Standards:
1. EN EN 1186-3： Materials and articles in contact with foodstuffs - Plastics - Part 3: Test methods for overall migration in evaporable simulants
2. ISO 759： Volatile organic liquids for industrial use - Determination
of dry residue after evaporation on a water bath -
General method
3. ISO 6353： Reagents for chemical analysis -Part 1 : General test methods
