Test Principle
Put the solution to be tested into the solvent storage dish of the automatic feeding system, and the empty cup is heated, cooled and weighed at the set temperature. Repeat the steps until a constant weight value is reached. Evaporate to dryness on a water bath below the boiling point of the soaking liquid. The cavity is heated to 105°C, dried and cooled. After the evaporating dish is cooled, the constant weight is judged with a balance (sensitivity is 0.01 mg), and the experiment is terminated to meet the constant weight requirement of the project.

Features
Cool and Hot Dual Cavity Integrated Control System, Automatic Upgraded
- Featuring with an integrated system of water bath evaporation, drying, cooling and constant weight, the testing is automatic, high efficiency and precise.
- Automatic feeding mechanical design, pneumatic valve control feeding, the residual amount is less than 0.1 mL, the testing does not need to wait and manual duty.
- The cavity has a built-in water bath, which can automatically detect the water level through the liquid level sensor, automatically add water to replenish water and drain, and automatically control the temperature of the water bath.
High-precision Imported Balance, Isolation Protection Design
- There are 3 built-in high-precision imported balances with a resolution of 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 weighing, the temperature and humidity are stable.
Meet High-throughput, High-availability Testing Needs
- Equipped with 18 testing stations with independent data, which can meet the needs of high-throughput testing.
- The sample to be tested can be purified water or organic solvent such as n-hexane, ethanol, acetic acid, chloroform, etc.
Cooling Recovery System, Efficient Solvent Recovery
- The built-in circulating water cooling pump continuously supplies circulating water to keep the cavity low temperature. Efficient and environmentally friendly, it can be cooled to room temperature within 30 minutes.
