Product Description
Industrial hygiene air sampling needs a compact impinger that draws air through a collection liquid at a known rate. This graduated midget impinger follows the proven Greenburg-Smith design in a smaller format, needing only a 12 inch head of water to operate.
This listing is for Kimble catalog number 737550-0000: Graduated Midget Impinger, Replacement Parts. The impinger is made from borosilicate glass 3.3 meeting USP Type I and ASTM E438 Type I, Class A. A 1 mm bottom orifice passes 0.09 to 0.11 CFM of air at 12 inches of water vacuum. The 30 mL receiver is graduated from 5 to 30 mL, and pieces are interchangeable while maintaining nozzle centering and bottom clearance. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
