Glass Impinger

Impingers are small bottles used with an air sample pump to collect airborne hazards into designated collection liquids for analysis. For personal exposure measurement the impinger mounts in a holster accessory near the breathing zone. For area monitoring the impinger is mounted on the side of a pump with a holder accessory. SKC offers impingers in Pyrex® glass or PFA (fluoropolymer) to meet your applications.

Glass Midget Impingers

SKC laboratory-quality glass impingers 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. Serial numbers on both sections assist with sample identification and proper part matching.

The Glass Midget impingers are available with a standard nozzle, or fritted nozzle (170 to 200 µm glass frit) which increases contact between the air sample and the liquid. Both types are also available as a spill-resistant model, which features a special outlet side arm that extends midway down with sufficient capacity above to handle all liquid in the standard or fritted impinger.
