Laboratory Equipment Functions
-
Balance Beam: Used primarily in gymnastics for measuring balance, it serves as a metaphor for precision in scientific measurements. Precision is vital for successful experiments.
-
Beaker: This laboratory staple has a flat base and wide mouth. It is essential for holding and mixing liquids, accommodating various chemical reactions that may occur during experiments.
-
Crucible Tongs: Essential for handling hot glassware and materials, these tongs protect the user from burns and injuries while transferring heated items.
-
Dropper: A small device that allows careful transfer of liquids in controlled amounts. Typically made from plastic or glass, it utilizes a bulb mechanism for suction.
-
Erlenmeyer Flask: Recognized by its wide base and narrow neck, this glass flask is ideal for titrations and can hold specific volumes, commonly found in 125 mL, 250 mL, and 500 mL sizes.
-
Evaporating Dish: Constructed from ceramic, this dish withstands high temperatures required for heating solutions, facilitating the evaporation of solvents.
-
Funnel: Designed for transferring liquids, it features a wide circular opening at the top and a narrow spout, ensuring spill-free pouring into containers.
-
Graduated Cylinder: Known as a measuring cylinder, this glass instrument is marked with precise measurements, allowing for accurate liquid volume assessment.
-
Mortar and Pestle: A paired set used for grinding and mixing substances, commonly found in kitchens and laboratories to create fine powders or mixtures.
-
Petri Dish: An essential tool for culturing microorganisms, its shallow dish design promotes growth and is widely utilized in microbiology.
-
Pipette: A slender and elongated tool, pipettes draw up specific liquid volumes with precision, essential for accurate measurements in experiments.
-
Stirring Rod/Glass Rod: This glass cylinder is utilized for mixing solutions and transferring liquids, promoting homogeneity in reactions when stirring contents.
-
Test Tube: A versatile glass tube open at one end, commonly used in experiments for holding, mixing, or heating small liquid samples efficiently.
