| Make Accurate Air Pollution Measurements with These High Quality Impingers |
Save space and stay accurate with a compact impinger graduated from 5–30 mL in 5 mL increments for precise gas absorption. The Gas Bubbler Impinger has a fritted glass stopper and creates tiny air bubbles for more efficient absorption, required for NO2 tests. On the Midget Impinger, the bottom orifice is 1 mm, with a 24/40 stopper assembly. These are required for quantitative analysis with air pollution testing kits. Size of both: 7″L x 1″ dia.
