Impingers and Bubblers for Air Sampling

For collecting various airborne gases, vapors and particulates using a high flow sampling pump.

Gilian Impingers are special glass tubes designed to collect airborne contaminants by bubbling the sampled air at a high flow rate through a method-specific absorbing liquid inside. The impinger liquid used can be analyzed to determine airborne contaminant levels. Impingers can be mounted directly to the high volume pump or a special spill-proof version can be attached to the worker’s collar with a clip. 

Midget Impingers, 25 ml - Standard, "Bubbler" and Special

These two-piece glass impingers have a capacity of 25 ml and a graduated scale along the side in 5 ml increments. The tip is precisely spaced in relation to the bottom of the impinger. 

• The Standard Midget Impinger has its two glass pieces joined by a 24/40 ground joint.
• The "Bubbler" or Fritted Midget Impinger is like the standard impinger, except it has a special fritted tip to increase the interaction between the air sample and the impinger liquid by breaking the air stream into smaller bubbles and thereby increasing surface area.
• The Special Midget Impinger has a Teflon® sleeve on the glass stopper, allowing its use for ozone sampling.

Micro Spill-Proof Midget Impinger

 This impinger is designed with traps to keep the liquid from spilling out, should they be tipped accidentally. It comes with a collar clip, allowing placement within the worker’ s immediate breathing zone. Very light in weight, the micro spill-proof impinger has a capacity of 2 oz (50 ml) and is made of PVC coated glass.

Moisture Traps & Holders

Moisture traps are designed to prevent ­moisture carryover from the impinger that might internally damage the sampling pump. Single and double holders are available for midget impingers and traps. A mounting bracket is also required when mounting these holders to Gilian 5000, Gilian 3500, GilAir-3, GilAir-5, or BDX II pumps.
