摘要

Climbed guidelines for the study of chemistry, which is essentially characterized by constituting a set of transparent laminar elements of edges, straight, obtuse or acute, which determine the angles of the glass conduits used in the chemical laboratory, which present on its surface a series of trepados, that represent material of laboratory, in different scales, feasible to transfer it to a writing following the edges of the climbed, allowing to form all the schematic organization of a chemical process, including the guidelines in its edge some metric scales for its use as a rule graduated (Machine-translation by Google Translate, not legally binding)
