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

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
Used as an easy and cost effective way
of transferring small volumes of liquid.
Glass Pipettes
For funneling liquids from one container to another or for filtering when equipped with filter paper.
Glass Funnel
Used in the laboratory for vacuum-assisted liquid filtering
It helps remove moisture from the final product.
Buchner funnel
Used in the lab for liquid-liquid extractions,
separating a mixture’s components into two solvent phases of different densities.
Separatory funnel
Used to take small amounts of compounds that are basically powder.
Porcelain spatula
Used for scraping, transferring, or applying powders and paste-like chemicals or treatments.
Stainless spatula
Apparatus Used to Observe Reactions
O Test tube
O Spot Plate
O Watch Glass
O Evaporating Dish
Used to observe chemical reactions, mix solutions, heat solutions, melt or burn solids, and perform chemical analysis.
Test tube
Also called a reaction plate is a laboratory tool made either from ceramics or plastics.
White color, allowing easy observation of reaction changes and color changes.
Spot Plate
Round, concave glass dish used for evaporation in chemistry.
Watch Glass
A piece of laboratory glassware used for the evaporation of solutions and supernatant liquids, and sometimes to their melting point
Evaporating Dish
Apparatus Used for Support
O Clamp Holder
O Iron clamp
O Clay Triangle
O Iron Stand
O Test tube rack
O Tripod
O Beaker holder
O Test tube holder
O Crucible tong
O Forceps
Used to hold things and is placed in an iron stand to elevate other equipment.
Iron clamp
A piece of laboratory apparatus that is
used to secure laboratory clamps
Clamp Holder
A wire and ceramic triangle used
to support a crucible while it is heated
Clay Triangle
Supports the iron ring when heating substances or mixtures in a flask or beaker
Iron Stand
Laboratory equipment used to hold upright multiple test tubes at the same time.
Test tube rack
To support or hold the flasks and beakers during experiments.
Tripod
Used for holding a beaker in place when the beaker is hot or should not be touched
Beaker holder
Used for holding a test tube in place when the tube is hot or should not be touched
Test tube holder
Allows the users to grasp a hot crucibles, flasks, evaporating dishes, or even small beakers.
Crucible tong
For gripping and manipulating small or delicate objects.

Apparatus with Specific Purpose
O Condenser
O Reagent bottle
O Suction flask
O Distilling flask
O Adapter
O Thermometer
O Mortar & pestle
O Triangular file
O Test tube brush
O Wash bottle

O Aspirator and dropper bulb
O Conductivity Apparatus
Laboratory apparatus used to condense vapors — that is, turn them into liquids — by cooling them down
Condenser
Special container for various liquids and solid reagents in the laboratory.
Reagent bottle
The solid parts are trapped by the filter and the liquid is drawn through the funnel into the flask below by a vacuum action.
Suction flask
Used in a distillation set-up: it connects to the lower end of the condenser and serves to direct the distilled liquid into the receiving flask.
Adapter
Forming part of larger distillation assemblies used for the separation and/or purification of liquids or liquid mixtures where the components have different boiling points.
Distilling flask
Used to take temperature of solids, liquids, and gases.
Thermometer
Used to crush solids into powders for
experiments, usually to better dissolve the solids.
Mortar & pestle
Used for cleaning test tubes and narrow mouth laboratory glassware, such as graduated cylinders
Test tube brush
Used to supply precise and small quantities of various liquids.
