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
Example of a stirring rod. A glass stirring rod, glass rod, stirring rod or stir rod is a piece of laboratory equipment used to mix chemicals. They are usually made of solid glass, about the thickness and slightly longer than a drinking straw, [clarification needed] with rounded ends.
Laboratory glassware is composed of silica, which is considered insoluble in most substances, with a few exceptions such as hydrofluoric acid or strong alkali hydroxides. Though insoluble, a minute quantity of silica will dissolve in neutral water, which may affect high precision, low threshold measurements of silica in water.
The right-hand drawing is about half the scale of the others and shows the shelf in use inside a pneumatic trough. A beehive shelf is a piece of laboratory equipment, usually of pottery, used to support a receiving jar or tube while a gas is being collected over water with a pneumatic trough. It is used so that when the gas emerges from the ...

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 ...
Clamp holders can secure laboratory equipment at specific angles, diameters, and weights, as required. [3] Clamp holders are often used to hold the attached apparatus over a work surface. There are several different types of holders, such as swivel holders and all-position holders, that allow adjustments for different angles and planes. In some ...
In chemistry, a retort stand, also called a clamp stand, [1] a ring stand, [2] or a support stand, [3] is a piece of scientific equipment intended to support other pieces of equipment and glassware — for instance, burettes, test tubes and flasks. [4] The typical ring stand consists of a heavy base and a vertical rod, both usually made of metal.
