Apparatus used to measure
volume
O Beaker
O Pipette
O Erlenmeyer Flask
O Volumetric Flask
O Graduated Cylinder
O Burette
Used to hold and heat liquids. Multipurpose and essential in the lab.
Least accurate instrument for
measuring volume
Beaker
Used to measure a volume of liquid that is being transferred to another container
Used for accurately measuring and delivering small volumes of liquid-usually 0.1-25 mL
Pipette
Used to heat, mix, and store liquids.
The advantage to the _ _ is that the bottom is wider than the top so it will heat quicker because of the greater surface area exposed to the heat.
Erlenmeyer Flask
Used to measure a single predetermined
volume
Used to measure one specific volume in mixing accurate solutions.
Volumetric Flask
Used to measure the volumes of liquids.
Graduated Cylinder
Used in titrations to measure precisely how much liquid has been delivered.
Burette
Used to measure mass very precisely.
Such devices typically have a reading error of ±0.05 grams. Its name refers to its three beams, where the middle beam is the largest, the far beam of medium size, and the front beam the smallest.
Triple Beam Balance
Apparatus/equipment used to measure mass
O Triple Beam Balance
O Analytical Balance
O Top Loading Balance
The most precise because it has a higher readability, measuring to the nearest 0.0001g.
Analytical Balance
This is another balance used primarily in a
laboratory setting. They usually can measure objects weighing around 150–5000 g.
Top Loading Balance
Apparatus Used for Heating Purposes
O Tirril Burner
O Bunsen burners
O Fisher Meker Burner
O Fishtail / wing top
O Hotplate
O Florence flask
O crucible with cover
O Alcohol lamp
O Deflagrating spoon
O Laboratory Oven
O Laboratory Incubator
Used for safe continuous stream of flammable gas used for heating, sterilization and combustion and specialize for finely controlled air / gas mixture
Tirril Burner
Type of gas burner commonly used as a
heat source in laboratory experiments. The burner consists of a flat base with a straight tube extending vertically, known as the barrel or chimney.
Bunsen Burner
A laboratory burner that produces multiple open gas flames, used for heating, sterilization, and combustion.
Fisher Meker Burner
Frequently used in the laboratory to perform chemical reactions, to heat samples, and for numerous other activities. _ _ are conceptually simple – a flat surface with heating elements. They do
not produce open flames and are well suited for oil or sand bath use.
Hotplate
It is designed for uniform heating, boiling, distillation and ease of swirling; it is produced in a number of different glass thicknesses to stand different types of use.
Florence flask
Used in the laboratory to contain chemical
compounds when heated to extremely high temperatures
Crucible with cover
Used for heating, sterilization, and combustion in a laboratory. The alcohol lamp uses ethyl alcohol or spirit as a fuel.
Alcohol lamp
Used in chemistry experiments when the burning of phosphorus, sulfur or another substance is required. It is capable for high temperatures.
Deflagrating spoon
Used for high-volume thermal convection
applications. This device is used for drying, material testing, curing, and heated storage
Laboratory Oven
Essential equipment in the laboratory that
provides a temperature-controlled environment to support growth of microbiological cultures.
Laboratory Incubator
Apparatus Used for Transferring Purposes
O Pasteur Pipettes
O Glass Pipettes
O Glass Funnel
O Buchner funnel
O Separatory funnel
O Porcelain spatula
O Stainless spatula
O Rubber policeman
Used to transfer small amount of liquids and samples
Pasteur Pipettes
