Smoke toxicity test device

1Equipment Overview

Smoke toxicity test deviceIt is developed based on the research results of China's quantitative production of material smoke methodology in the laboratory and the experimental mouse acute inhalation smoke toxicity test methodology, as well as the experimental experience of material smoke toxicity evaluation. This device is suitable for the classification of toxicity hazards in materials that produce stable smoke, and is not applicable to the classification of toxicity hazards in materials that produce unstable smoke.

4Main Features

1Microcomputer control and computer operation;

2Calibration of heating temperature for circular furnace: display time, temperature curve, and actual measured temperature comparison chart, automatically calculate real-time display of the rotation chart of the squirrel cage's angular velocity after setting the material's smoke production concentration and smoke production rate, set the running time of the circular furnace arbitrarily, and have manual and automatic fast forward and rewind functions for the circular furnace;

3Quartz tubes and quartz boats are made by firing quartz glass, which has a beautiful appearance and is convenient and practical.

4Smoke collection and distribution components. Large caliber three-way ball valve ensures smooth flow of flue gas.

5Mouse cage rotation and mouse motion recording system Specially designed mouse rotating cage, lightweight, flexible rotation, no fixed stationary point; High precision speed measurement device ensures the accuracy of the experiment.

6Poison box Made of metal bracket and organic glass, sturdy and durable, easy to observe.

7The air supply system uses high-power air pumps for stable airflow; The control part is a glass rotor flowmeter, which is economical, practical, and easy to operate for test preparation.
