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
