SKC Impingers and Accessories

About Midget Impingers (Glass Bubblers)

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.

Laboratory-quality Midget Impingers (Glass Bubblers)

SKC impingers (glass bubblers) have graduations that are accurate to within ± 0.5 ml for each increment. This helps reduce volumetric measurements required in the field and in the laboratory, while also saving time and money.

Impinger and in-line trap in holder mounted on sample pump.

Use a trap with impingers to prevent impinger liquids from being drawn into the sample pump. Solid sorbents may be added to the trap to protect the pump chamber from exposure to vapors when using a volatile liquid.

SKC fritted impingers are classified as very coarse with a 170 to 220 µm glass frit.
