Alcohol Lamp: Provides a heat source for conducting small experiments or chemical reactions. It's often used when precise, low-temperature heating is required. 2. Wire Loop (nichrome wire): Used to introduce substances to flames to observe color changes, often in flame tests. Nichrome wire withstands high temperatures without degrading. 3. Beaker: Holds, mixes, or heats liquids and other substances. Its wide mouth and flat bottom make it ideal for handling larger volumes. 4. Bulb Flask: Designed for mixing chemicals and reactions, especially those needing containment. Its round bottom allows even heating. 5. Base Burette: Measures and dispenses precise amounts of basic (alkaline) solutions in titrations. It has a stopcock for controlled release. 6. Acid Burette: Dispenses accurate volumes of acidic solutions in titrations. Its material resists acidic corrosion, ensuring accuracy. 7. Bar Magnet: Creates a magnetic field for experiments involving magnetism and attraction. Often used to demonstrate magnetic properties. 8. Clamp Holder: Holds and stabilizes laboratory equipment, like burettes or test tubes, on a stand. It's essential for hands-free experiments. 9. Burette Clamp: Holds a burette securely to a stand for precise dispensing during titrations. Adjustable to fit various burette sizes. 10. Clay Triangle: Supports crucibles while heating over a flame. Its triangular shape allows stability during heating. 11. Condenser: Cools hot vapors in distillation setups to condense them back into liquid form. Commonly used in organic chemistry. 12. Crucible with Cover: Heats small quantities of substances to high temperatures. The cover helps contain reactions and prevent contamination. 13. Crucible Tong: Safely holds and transfers hot crucibles. Provides a secure grip during high- temperature processes. 14. Cork: Seals containers like test tubes or flasks, preventing contamination or spillage. Often used when storing solutions temporarily. 15. Rubber Stopper: Seals test tubes and flasks for mixing or containing reactions without leaking. Offers flexibility for various sizes. 16. Distilling Flask: Holds liquids that require separation via distillation. Its design allows for easy attachment to a condenser. 17. Evaporating Dish: Evaporates solvents to leave behind concentrated solutions or residues. Withstands high temperatures without breaking. 18. Erlenmeyer Flask: Used for mixing, heating, and storing liquids, especially when swirling is required. Its narrow neck reduces spill risk. 19. Florence Flask: Holds, heats, or boils liquids, with a rounded bottom for even heat distribution. Ideal for long-term heating experiments. 20. Forceps: Picks up small, delicate, or hazardous materials. Often used in biology or chemistry labs for precise handling. 21. Funnel: Guides liquids or powders into containers with narrow openings. It minimizes spills and ensures accurate transfer. 22. Glass Tubing: Connects apparatuses to transport gases or liquids. Often used in distillation or gas collection setups. 23. Graduated Cylinder: Measures accurate liquid volumes. Calibrated markings ensure precise volume readings. 24. Test Tube: Holds small amounts of substances for testing or reactions. Useful for observing changes in experiments. 25. Iron Stand: Provides support for equipment in experimental setups, like heating with a Bunsen burner. Ensures stability and safety. 26. Iron Ring: Holds beakers or flasks over a flame when connected to an iron stand. Essential for heating experiments. 27. Medicine Dropper: Transfers small, precise amounts of liquid. Useful for adding drops in chemical reactions. 28. Mortar and Pestle: Crushes and grinds substances into fine powders. Commonly used in chemistry and biology labs. 29. Pipetor: Draws and dispenses liquids with precision. Ensures accurate measurements in small volumes. 30. Pipette: Transfers measured amounts of liquids accurately. Essential for precise liquid handling in experiments. 31. Water Bath: Heats substances evenly without direct flame exposure. Common in biological and chemical labs for temperature control. 32. Glass Rod: Stirring rod for mixing chemicals or solutions. Its inert nature prevents reactions with most chemicals. 33. Spatula: Transfers small quantities of solid chemicals. Useful for handling powders and crystalline substances. 34. Separatory Funnel: Separates immiscible liquids, like oil and water. Commonly used in extraction processes. 35. Triangular File: Scores glass for cutting. Often used in custom glass tube or rod adjustments. 36. Tripod: Holds containers over a flame for heating. Provides stable support during heating processes. 37. Water Bath: Used again for controlled heating, especially for reactions needing gentle heat. Ideal for incubating samples at constant temperatures. 38. Thermometer: Measures temperature accurately in experiments. Used to monitor reaction conditions. 39. Test Tube Holder: Holds test tubes, especially when heating them. Protects hands from hot or hazardous substances. 40. Test Tube Rack: Holds multiple test tubes upright for organization. Useful for comparative experiments with multiple samples. 41. Test Tube Brush: Cleans test tubes and small glassware. Ensures cleanliness before reuse in experiments. 42. Bunsen Burner: Provides a heat source for various experiments. Offers an adjustable flame for controlled heating. 43. Spot Plate: Holds small samples for reactions or testing. Useful for qualitative chemical analysis. 44. Volumetric Flask: Prepares precise solution volumes. Essential in quantitative analysis for preparing standard solutions. 45. Watch Glass: Holds samples for observation, drying, or small reactions. Often used to cover beakers or evaporating dishes. 46. Wire Gauze: Supports containers being heated and spreads flame evenly. Prevents glassware from direct flame exposure. 47. Iron Clamp: Secures equipment on a stand for stability. Often used with other apparatus for multi-level setups. 48. Rubber Tubing: Connects equipment for gas or liquid flow. Used in setups requiring flexible, airtight connections.
