Teflon vacuum traps for collecting atmospheric pollutants by solution absorption method.In order to collect a certain pollution component in the atmosphere, a solution of a specific component is loaded into the absorption bottle. When the gas passes through the absorption liquid, the pollutant to be measured is absorbed. The concentration of the pollutant in the atmosphere can be determined by analysis and determination.
The most important performance index of the absorption bottle is the optimum sampling flow rate, absorption efficiency and resistance drop under the condition of filling a certain amount of absorption liquid.

PTFE material absorption bottle corrosion resistance, metal element blank value is low, can withstand strong acid strong alkali, and various organic solvents.
