Midget Bubbler

I chose to learn about and discuss the Midget Bubbler.  When I first came across this device, it reminded me of something you might have seen in a head shop in the 70′s or perhaps something used behind the bar at your local tavern. 

 

 

 

 

 

 

For those Mid-Westerner’s, it is my understanding that the word “Bubbler” refers to a drinking fountain like the one pictured to the right.  Well, wrong on all of the above.

The Midget Bubbler is used in determination of Acrolein: 4-Hexylresorcinol Method #1. Bottle has encircling graduations from 0 to 25mL or 0 to 30mL in 5mL divisions. Inlet/ outlet are 7mm O.D. For 0-25mL bottle.

Well, there you have the specifications, the  Bubblers/Impingers in general 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.

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.  So, there you have it.  Of course, our knowledgeable Team here at OpticsPlanet are are available to assist you.

As always, thank you for reading my blog.  Comments are certainly welcome.
