Chemical apparatus used to purify chemicals
Chemical equipment. Engraving of equipment used to purify chemicals by sublimation. This process involved heating a solid until it turns into a gas, leaving impurities behind. The gas turns back into a solid (the sublimate) when it is cooled. In this image, the rounded flask containing the original sample is at left. After the flask was placed in a furnace, the bell- shaped receptacle (at right) was connected to the flask to collect the sublimate. Image taken from a 1545 book which credited the design of this equipment to the Arabic alchemist Geber (721-815)

Apparatus Furnace History Of Science 16th Cent
EDITORS COMMENTS
This print showcases a historical chemical apparatus used for the purification of chemicals through sublimation. Dating back to the 16th century, this engraving depicts an intricate setup designed by the renowned Arabic alchemist Geber (721-815). The process involved heating a solid substance until it transformed into a gas, leaving impurities behind. As the gas cooled down, it would turn back into a solid form known as the sublimate. In this image, we can observe two key components of Geber's apparatus. On the left side stands a rounded flask containing the original sample to be purified. This flask was then carefully placed in a furnace for controlled heating. To collect and contain the resulting sublimate, an intriguing bell-shaped receptacle is connected to the flask on its right side. The significance of this ancient technique lies not only in its contribution to early chemistry but also in its representation of scientific progress throughout history. It serves as a testament to human curiosity and innovation that has paved the way for modern advancements in chemical purification methods. This remarkable photograph from Science Photo Library offers us glimpses into our scientific heritage and reminds us of how far we have come in understanding and manipulating matter at its most fundamental level.
