39533-12EC PYREX Gas Dispersion Tubes with 12mm O.D. Extra Co

Corning These 12mm diameter PYREX® gas dispersion tubes have an extra coarse porosity (170 to 220µm) fritted disc and are used to disperse or scrub gas in liquids. The size of gas bubbles depends upon the porosity of the fritted disc and the liquid used. The finer porosity discs give smaller bubbles, however greater gas pressure is required. The 12mm O.D. fritted cylinder permits insertion through small openings.
