Double Midget Impinger Holder, stainless steel, for attaching two impingers, or impinger and trap, to air sample pump; not suitable for PFA impingers_x000D_
Impingers are Pyrex glass bubble tubes designed for the collection of airborne hazards into a liquid medium. When using a personal air sampler, a known volume of air bubbles is pumped through the glass tube that contains a liquid specified in the method. The liquid is then analyzed to determine airborne concentrations. An impinger may be mounted on the side of an air sample pump or put into a holster and placed near a worker's breathing zone.
