It seems to be an aerator (air pump). I believe he used the pump with 2 ports and blocked one off because the 2 port will pump a larger volume of air v.s. the one with a single port.

Really? See this:

Auful,
What I was describing was for a positive pressure system not a vacuum system (pump air into the sealed reaction container, fumes get pushed into scrubber).
I believe the $25.00 Mini Scrubber is a positive pressure system.
-I have made my own version of this design (thank you jeneje for the idea).
-I started with a 1000 ml round bottom beaker and stopper. Drilled 2-1/4" holes through the stopper.
-Using an aquarium aerator manifold with 3 accessory valves. I removed the internal check valves and filter. I am using the manifold in reverse of its intended purpose.
-I connected the aerator pump to the 2 outside manifold valves saving the center one for a syringe. The now exit port of the manifold was connected by hose to the stopper with about 4" of the hose below the stopper.
-The second hole in the stopper was connected to a hose flush with the bottom of the stopper and plumbed outside.
-since the added syringe is connected to the manifold via a valve I can add peroxide to the HCL foil solution without having to open the chamber at all.
So far I could not be happier, as jeneje said "no smell at all"
Thanks again jeneje.
Derek
P.S. I will post a picture of this later.
