What is a spatula chemistry?
Laboratory spatulas are implements with flattened ends used to mix, spread and lift chemicals. Spatulas are most commonly made of stainless steel to provide clean mixing and prevent corrosion. Other materials include rubber and certain polymers such as Nylon®. Spatulas can have soft or stiff blades.
What is a tong in laboratory?
Tools used to grip and lift objects instead of holding them directly with hands; available in a variety of shapes and with a range of prong counts for specialized applications including holding crucibles, beakers, or flasks.

A wash bottle is a squeeze bottle with a nozzle, used to rinse various pieces of laboratory glassware, such as test tubes and round bottom flasks. … When hand pressure is applied to the bottle, the liquid inside becomes pressurized and is forced out of the nozzle into a narrow stream of liquid.
What is clay triangle in chemistry?
Clay triangle
A triangular device made of heat-resistent clay. Used to hold crucibles and porcelain dishes heated by a Bunsen burner.
What is crucible chemistry?
A crucible is a ceramic or metal container in which metals or other substances may be melted or subjected to very high temperatures. While crucibles were historically usually made from clay, they can be made from any material that withstands temperatures high enough to melt or otherwise alter its contents.
What is the use of a Scoopula?
Scoopula is a brand name of a spatula-like scoop utensil used primarily in chemistry lab settings to transfer solids: to a weigh paper for weighing, to a cover slip to measure melting point, or a graduated cylinder, or to a watch glass from a flask or beaker through scraping.
