Air bubblers

Fish and submerged plants depend on the equilibria between O2 and CO2 in the atmosphere and dissolved in the water. Home aquariums use air bubblers to maintain equilibrium concentrations by replenishing these gases. 

In addition to the level-measurement devices illustrated in Figure 7-3, there are air bubbler systems for level detection, ultrasonic level detectors, and radiation level detectors. Ultrasonic and... 

Analytical Methods. The official NIOSH recommended method for determining sulfur dioxide in air consists of drawing a known prefiltered volume of air through a bubbler containing hydrogen peroxide, thus oxidising the sulfur dioxide to sulfuric acid. Isopropyl alcohol is then added to the contents in the bubbler and the pH of the sample is adjusted with dilute perchloric acid. The resultant solution is then titrated for sulfate with 0.005 M. barium perchlorate, and Thorin is used as the indicator. 

Stability of 2,3,7,8-Tetrachlorodibenzo- >-dioxin Towards Air Oxidation Under Simulated Conditions. Air was bubbled through two borosilicate glass gas absorption bottles equipped with fritted glass bubblers. The first bottle contained 1-octanol for presaturation of the air, and the second bottle contained 1-octanol solutions of the dioxin treated as follows (1) octanol only, (2) octanol mixed with 74-105ju, glass beads to increase the surface area, and (3) octanol mixed with magnesium oxide to simulate a basic soil. The original solution and the sample solutions were scanned with a UV spectrophotometer at various time intervals for 4 days to determine the stability of 2,3,7,8-tetrachlorodibenzo-p-dioxin. 

Holes were tapped in the center of each piece of bar stock to accept A inch NPT pipe, and a Kordon Mist Air aquarium bubbler was glued into a smaller hole on the bottom inside of the bubbler.
