What do you use to mix small amounts of chemicals?
Stirring rod – A skinny solid glass rod used in chemistry to mix chemicals and liquids. A stirring rod is typically about the length of a long straw and has rounded ends. Test tube – A test tube is a glass or plastic tube used for holding, mixing, and heating small quantities of liquid chemicals.

What is used to hold small amount of liquid solution for testing?
A pipette, also known as a chemical dropper, is a glass or plastic tube used to suction small amounts of liquid to enable to transfer the liquid from one place another. They come in different types, each used for a specific purpose either for laboratory experiments or medical tests.

What equipment is used in the laboratory?
Electrically powered equipment found in the laboratory includes fluid and vacuum pumps, lasers, power supplies, both electrophoresis and electrochemical apparatus, x-ray equipment, stirrers, hot plates, heating mantles, microwave ovens, and ultrasonicators.
What is the Beaker used for in the laboratory?
The beaker is one of the most common pieces of glassware in the laboratory. It is a simple cylindrical container used to hold solids and liquids with sizes ranging from very small (10 mL) to very large (4,000 mL). It has a lip for ease of pouring and decanting liquids.
What are the apparatus and procedures used in chemistry?
Common apparatus and procedures. COMMON LABORATORY APPARATUS Beakersare useful as a reaction container or to hold liquid or solid samples. They are also used to catch liquids from titrations and filtrates from filtering operations. Laboratory Burnersare sources of heat. Buretsare for addition of a precise volume of liquid.
What is glassware used for in the laboratory?
Glassware is a regular appearance in the professional chemistry laboratory, because it has a relatively low cost, extreme durability, and specific levels of precision. While some labware is being supplemented with plastic or even everyday kitchen materials, glass is still the standard material by which laboratory work is done.
