For collecting various airborne gases, vapors and particulates using a high flow personal sampling pump.
Impingers are special glass tubes designed to collect airborne contaminants by bubbling the sampled air at a high flow rate through a method specific asbsorbing liquid inside. The liquid used can then be analyzed to determine airborne contaminate levels.
Zefon midget impingers consist of 2 piece of glass fitted together using a 20/40 ground joint. They have a capacity of 25 ML with a graduated scale along the side in 5ML. Each features a nozzle tip which is precisely located in relation to the bottom of the impinger.
