摘要

Pedagogical case for the analysis of minerals, characterized in that it is constituted by a box, whose lid houses a rectangular piece, suitable to serve as a base on which the experiments are made and held by a rubber provided with a brooch; whereas the box carries compartments destined to contain, on the one hand, the closed tubes, of diverse forms, that lodge the necessary reagents, and on the other, those that contain the samples of minerals; and has other departments for a rack with test tubes, metal and plastic tweezers, porcelain wells, dropper pipettes, wick, distilled water bottles, tubes with platinum wire, stirrers, spoons and general elements necessary to perform the analysis of minerals.
