PYREX™ Gas Dispersion Tubes With Fritted Cylinders

These immersion tubes have a 30 mm diameter medium porosity (10 μm to 15 μm) fritted disc and are particularly useful for drawing off the supernatant liquid from a precipitate. They are made from Code 7740 borosilicate glass. Any precipitate which might be disturbed will be held on the filter. Solid chemicals, made in a beaker or flask, can be filtered and washed without being transferred.
