COMMON LABORATORY APPARATUS EQPT, AND THEIR USE Flashcards
QUIZ
It is used to broadly test whether a solution is acidic or basic and comes in 3 types- red, blue, and neutral.
Litmus Paper
Are pieces of paper that change color depending on the pH – the acidity or alkalinity – of a liquid.
pH Strips
These are most often found in a laboratory or places where extreme sensitivity is needed for the weighing of items.
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
This type of laboratory balance is less sensitive than a top-loading balance. They are often used in a classroom situation because of ease of use, durability and cost.
Triple-Beam Balance
It is a cylindrical glass or plastic vessel used for holding liquids.
Beaker
Used to measure temperature in Celsius.
Thermometer
Used to pick up beakers.
Beaker Tongs
is a cone-shaped container with neck, so you can hold the flask or attach a clamp or use a stopper.
Erlenmeyer flask
It is characterized by having a bulb and a long neck.
Volumetric flask
It is a relatively slim glass or plastic cylinder used specifically for calibrating beakers or measuring a liquid’s volume. Come in a variety of sizes such as 10 ml, 25 ml, 50 ml,100 ml, 500 ml and 1,000 ml.
Graduated cylinder
It is a cylindrical, laboratory glass apparatus that is used to measure the volume of liquids.
Burette
It is a device with a piston-driven air displacement mechanism used to transport a given volume of liquid mostly in the laboratory.
Dropper Pipette
Transfers relatively small amounts of liquid. In the most commonly used pipettes, experimenters draw liquid into one end of a glass or plastic cylinder by the prior squeezing of the rubber or plastic ball at the opposite end.
Pipette
Used to hold and mix liquids.
Test Tube
Used to rinse pieces of glassware and to add small quantities of water.
Wash Bottle
Used to hold solids while they are being weighed or to cover a beaker.
Watch Glass
Used to hold a test tube, particularly when hot.
Test Tube Clamp
Used to hold several test tubes at one time.
Test Tube Rack
Used to pick up or hold small objects.
Forceps
Used to transfer liquids or fine-grained materials into containers with small openings. Also used for filtration.
Funnel
Used to crush and grind materials.
Mortar and Pestle
Used for stirring and mixing.
Stirring Rod
one of the most well-known pieces of laboratory equipment found within school science labs. It consists of a mixing tube which is used to generate a mixture of gas and air.
Bunsen Burner
Are normally used for heating solutions to 100o C or above when inherently safer steam baths cannot be used.
Hot Plates
Are commonly used in the laboratory to remove water or other solvents from chemical samples and to dry laboratory glassware.

Evaporating Dish
Used with a ring stand to hold glassware, such as a beaker or a funnel.
Ring Clamp
Used to support a container, such as a beaker, on a ring stand while it is being heated.
Wire Gauze
Used to hold or clamp laboratory glassware and other equipment in place, so it does not fall down or come apart.
Ring Stand
Used to support glassware, such as beakers and flasks, especially when heating substances.
Tripod Stand
