KONTES* Midget Impinger, TS 24/40, Graduated

Almost identical in principle and design to the Greenburg-Smith impinger, except for its smaller size. Only a 12 in. head of water is required. The orifice at the bottom of the impinger is 1 mm, passing 0.09 - 0.11 CFM of air at 12 in. water vacuum. Pieces are interchangeable, maintaining nozzle centering and clearance to the bottom inside surface. These impingers were designed for the sampling of small air volumes with a low jet velocity. 30 ml capacity. Graduations at 5 - 30 ml; 5 ml subdivisions. Approximate overall height: 180 mm.
