Game of test tube samples held in a wooden double-platform test tube rack. This set was manufactured by Enosa, which was created by the National Institute of Industry in 1951. It manufactured precision optical equipment under the guidance of the German company Zeiss. Together with other trading houses, it played a significant role in the modernization of teaching supplies. It provided a diverse range of supplies for teaching the experimental sciences, from laboratory glass to projectors and sound recorders.
This piece is from a collection of teaching and laboratory supplies from the Andrés Manjón elementary school in Zaragoza.
