Flashcards
Pipette
Pipette
Used to transfer small amounts of liquids, typically measured in milliliters (mL) or microliters (μL).
Test Tube
Test Tube
A container used to heat, hold, and mix small amounts of liquid or solid chemicals during experiments. Made of heat-resistant glass.
Funnel
Funnel
A funnel is used to transfer liquids or fine-grained chemicals into labware with a narrow opening, effectively directing the flow without spills.

Study Notes
Laboratory Equipment and Uses
-
Spatulas: Used to transfer samples or chemicals from containers to weighing paper or weighing containers.
-
Flasks: Used for making solutions and volumetrically measuring chemicals, samples, or solutions for various processes like mixing, heating, cooling, dissolving, precipitation, boiling (distillation), and analysis.
-
Funnels: Used to channel liquids or fine-grained chemicals (powders) into labware with narrow necks or openings. Can be used with filter paper to filter (remove fine particles) liquids.
-
Pestle: Used to crush, mash, or grind materials in a mortar.
-
Buret: Used to deliver solutions in precisely-measured, variable volumes.
-
Dropper: Used to transfer small quantities of liquid.
Basic Laboratory Equipment (Continued)
-
Evaporating Dish: Used for the evaporation of solutions.
-
Pipette: A laboratory instrument used to measure or transfer small quantities of liquid (milliliters or microliters).
-
Beakers: Used for transporting and mixing solutions.
-
Graduated Cylinders: Used to measure the volume of liquids.
-
Crucible: A ceramic or metal container used to burn, melt, or mix solid chemical compounds over a burner, often at high temperatures.
-
Test Tubes: Used to heat, hold, and mix small amounts of liquid or solid chemicals in experiments. Made of borosilicate glass to resist temperature changes and chemical reactions. Transparent for observation.
