Never use the same spoon or glass tubing with different reagents without washing and drying them first. T or F
True
Always clean apparatus in all your experiments. T or F
True

False (non-luminous)
Never leave an experiment unattended when heating or when reaction is taking place. T or F
True
Strong acids and bases should be diluted with water before being poured down the sink.
Water Soluble Liquid Wastes
For measurement of an amount of liquid.
Graduated Cylinder
Are 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.
Beaker
One of the most important apparatuses as they are functional from storing to mixing reagents in any chemical or biological reactions.
Test tube
A type of flask used as an item of laboratory glassware. It can be used as a container to hold solutions of chemicals.
Florence Flask
Used to contain liquids and for mixing, heating, cooling, incubation, filtration, storage, and other liquid-handling processes.
Erlenmeyer flask
Used to hold solids, evaporate liquids, and heat small quantities of different substances as per the need of the experiment.
Watch Glass
are made up of porcelain and are used to store and heat substances when required to be heated at high temperatures.
Crucible and cover
- Its mostly used in the titration reactions and is handful in delivering a known volume of any substance to other equipment. This apparatus is a long-graduated tube, with a stopcock present at the lower end.
Burette (Buret)
- To transfer liquids and samples during the laboratory workflow
Medicine dropper
- Used for filtering, filling, decanting or transferring liquids or powders from one vessel to another.
Funnel
- Used for mixing liquids, or solids and liquids.
Stirring Rod
- Used to prepare ingredients or substances by crushing and grinding them into a fine paste or powder
Mortar and Pestle
- Used in labs to separate liquids and solids from a solution by allowing the water to evaporate off into the air.
Evaporating Dish
- Used to measure temperatures or temperature changes with a high degree of precision.
Thermometer
- Used to measure out or transfer small quantities of liquid, in volumes of milliliters (mL), microliters (μL).
Pipette (Pipet)
- Used to separate mixtures of two liquids with different boiling points
Distilling Flask
- used for measuring accurate volumes of liquid materials for laboratory experiments.
Volumetric Flask
- Used to cool and condense a gas back to a liquid, often as part of the process of chemical distillation.
Liebig’s condenser
- To hold things and is placed in an iron stand to elevate other equipment.
Iron Clamp
Supporting apparatus above the work surface.
Iron Stand
The ____ serves to identify the pH of any solution by changing colors whereas, the _____ serves in the filtration process.
Litmus and filter paper
- Used to support a crucible while it is heated over a Bunsen burner.
Clay Triangle
- Usually used to keep glass beakers or flasks from breaking due to heat shock.
Wire Gauze
- Used in the laboratory to score glass tubing before cutting, then smoothing the edges before use.
Triangular File
- To hold test tubes securely while they are being filled, stirred, or heated.
Test tube holder
- Used to heat substances, to combust substances, and to sterilize objects on high heat
Bunsen Burner
- Used for the flow of fluids and gases.
Rubber tubing
- Used to lift a hot crucible from a furnace or for other items which cannot be handled with bare hands.
Crucible Tongs
- Used for cleaning test tubes and narrow mouth laboratory glassware, such as graduated cylinders, burettes, and Erlenmeyer flasks.
Test Tube Brush
Useful material to stop test tubes and flasks.
Cork
- Used to seal test tubes, flasks, and other containers during experiments or storage.
Rubber Stopper
- Used to hold upright multiple test tubes at the same time.
Test Tube Rack
- Most common laboratory balance that determines the mass of chemicals or objects with high accuracy.
Analytical Balance & Triple Beam Balance
- Used to support equipment such as beakers, flasks, and other glassware during experiments.
Tripod
- To help with mixing, scraping, and other tasks related to transferring materials and samples from one place to another.
