Casella Midget Impinger Sampling Heads (Bubblers)


Available on back-order

Impingers are glass tubes, containing a liquid sometimes required for specific material collection e.g. chlorine gas, isocyanates etc.

Air is drawn through the liquid in the Impinger and the sample is captured by the solution. This solution is then analysed by the laboratory for the contaminant.

Like sorbent tubes, this is usually done at low flow rates and so a low flow adaptor and constant pressure controller are also required or a specific low flow pump.  A typical Impinger sampling set-up is shown in the diagram below.

The Carbon Trap filters can also be purchased on this page.
