LABORATORY APPARATUS – CHEMISTRY 1 1. Test tube 18. Laboratory clamps a common piece of laboratory glassware consisting of a finger- Used to ensure a firm grip on the containers. like length of glass or clear plastic tubing. It is used by chemists to hold, mix, or heat small quantities of solid or liquid 19. Beaker tongs chemicals are used to grab and lift hot containers from a furnace or for other items that cannot be handled with bare hands. 2. Beaker a beaker is generally a cylindrical container with a flat 20. Triple beam balance bottom. Beakers can be used to hold liquid or solid samples or a device that is used to weigh materials because certain as a container for reactions. experiments demand correct quantities of ingredients, solids are often weighed before use. 3. Volumetric flask a type of laboratory flask, calibrated to contain a precise 21. Electrolysis setup volume at a certain temperature. Used to separate a compound or a malleable into its component parts. 4. Erlenmeyer flask Often used as reaction vessels, particularly in titrations. Also 22. Hexagonal weighing dish good for mixing. are uniquely designed for non-slip handling, pouring, and dispensing of solids and liquids when weighing. 5. Bunsen burner it produces a single open gas flame, and is used for heating, 23. Mortar and Pestle sterilization, and combustion. A mortar and pestle are used to grind up solid chemicals into fine powder and crush solids into smaller pieces. 6. Watch glass a circular concave piece of glass used in chemistry as a 24. Laboratory hot plate surface to evaporate a liquid, to hold solids while being used to heat samples, solutions, and materials uniformly weighed, for heating a small amount of substance, and as a without the danger associated with the open flame at cover for a beaker. precise temperatures 7. Burette 25. Wire gauze a long, graduated, glass tube marked with measurements An essential piece of supporting equipment in a laboratory and used in chemistry. as glassware cannot be heated directly with the flame of a Bunsen burner. 9. Filter Funnel They are used to transfer chemicals into small-mouthed 26. Glass vials receptacles. Filters, thistle, and falling are some of the various Are flat-bottomed glass containers with either screw-on tops types, and each has a specific purpose. or stoppers. They come in many sizes and shapes and are used to hold small amounts of liquids or solids. 10. Wash bottle It is a squeeze container used to clean and rinse 27. Safety goggles glassware. The majority of wash bottles are plastic. Provide eye protection from moderate impact and particles Depending on the task, you may fill it with ethanol or deionized associated with grinding, sawing, scaling, broken glass, minor water. chemical splashes, etc. 11. Test tube brush 28. Petri dish A cleaning tool used to brush and clean laboratory Used predominantly for the cultivation of organisms on solid equipment such as beakers, test tubes, flasks, and beakers. media. 12. Pipette (naa say plastic pipette) 29. Reagent bottles: wide-mouthed and narrow-mouthed Another way of measuring the volume of liquids. They are far Tapped by special caps or stoppers and are intended to more accurate than flasks and measuring cylinders of any kind. contain chemicals in liquid or powder form for laboratories They are sometimes used to hold liquids you intend to transfer and stored in cabinets or on shelves. them from one container to another. Narrow-mouth reagent bottles are generally used to store liquid 13. Rubber pipette (bulb) media and compounds like reagents. Commonly used in scientific fields that require precise measurement and dispensing of small amounts of liquids. The wide neck is ideal for solids, powders, and viscous liquids They are preferred over mouth pipetting for safety reasons and can also prevent contamination. 30. Graduated cylinder is a piece of laboratory glassware or plasticware used to 14. Spatula and Scoopula accurately measure out volumes of chemicals for use in Are used to scoop out solids out of containers and onto a reactions. They are generally more accurate and precise for crucible for weighing. They are sometimes used to mix this purpose than flasks. It is calibrated and used more often chemicals. because of its uniform shape. 15. Kipp's apparatus 31. Alcohol lamp The laboratory equipment takes a solid material and converts Also called as spirit lamp which is a piece of laboratory it into a gaseous state via liquid actions. equipment used to produce an open flame. It is used for heating short liquids. 16. Glass rod/stirring rod This handy laboratory equipment is a stirrer that is used to 32. Evaporating dish mix solutions. Are used for the evaporation of liquids and solutions to produce solid substance or concentrated solutions. 17. Centrifuge Used to separate fluids, gases, or liquids based on 33. 6 wells reaction plate density. In research and clinical labs, they are used for cell Are clear polystyrene plates that makes sample identification collection, organelle purification, virus purification, protein easy as each plate is organized into marked rows of wells. Not purification, and nucleic acid purification. intended for culturing. 34. Test tube holder  LABORATORY APPARATUS – CHEMISTRY 1 Used for holding test tubes when tubes are not to be touched. 35. Plastic measuring cups Are specific high-quality measuring tools for dry and liquid chemicals, powders, ingredients, medicines, and more. 36. Litmus paper and pH paper Contains a chemical that changes color as it makes contact into an acid or base. 37. Condenser A piece of laboratory equipment that is used to condense vapours in the lab to turn them into liquids simply by cooling them down. 38. Volumetric pipette Also known as bulb pipette, are manual liquid handling devices used in many laboratories or transfer and dispense of a single, specific quantity of liquid to a very high degree of accuracy. 39. Separatory funnel A glassware used in liquid-liquid extractions to separate the components of a mixture into two immiscible solvent phases of different densities. 40. Thistle funnel Used for pouring liquids or fine powders into containers with small openings. They are particularly useful when working with small volumes or when working with delicate or sensitive materials that require careful handling. 41. Tripod A three-legged platform used to support flasks and beakers. 42. Thermometer (alcohol/mercury) A thermometer is an instrument that is used to measure temperatures or temperature changes with a high degree of precision. 43. The U Tube contains water or mercury in a U-shaped tube, and is usually used to measure gas pressure.
