The Thiele tube, named after the German chemist Johannes Thiele, is a laboratory glassware designed to contain and heat an oil bath. Such a setup is commonly used in the determination of the melting point or boiling point of a substance. The apparatus resembles a glass test tube with an attached handle.
A Fisher–Johns apparatus. A melting-point apparatus is a scientific instrument used to determine the melting point of a substance. Some types of melting-point apparatuses include the Thiele tube, Fisher-Johns apparatus, Gallenkamp (Electronic) melting-point apparatus and automatic melting-point apparatus.
to heat things uniformly from all sides at a set temperature up to the boiling point of water Needle Destroyer: Burns the needle electrically either cuts the syringe manually or burns it electrically Sharps container [4] A imperforable container for sharp wastes like needles, blades, microscope slides, broken glass, etc.
A boiling tube is essentially a scaled-up test tube, being about 50% larger. They are designed to be wide enough to allow substances to boil violently as opposed to a test tube, which is too narrow; a boiling liquid can explode out of the end of test tubes when they are heated, as there is no room for bubbles of gas to escape independently of ...
Round-bottom flasks are often used to contain chemical reactions run by chemists, especially for reflux set-ups and laboratory-scale synthesis. [3] Boiling chips are added in distilling flasks for distillations or boiling chemical reactions to allow a nucleation site for gradual boiling. This nucleation avoids a sudden boiling surge where the ...
A Florence flask/boiling flask is a type of flask used as an item of laboratory glassware and is named after the city Florence. [1] It is used as a container to hold liquids. A Florence flask has a round body, a long neck, and often a flat botto
