Common Lab Apparatus

• beaker is a container for stirring, mixing, and heating liquids. generally cylindrical with a flat bottom and a lip for pouring.
• Erlenmeyer flask is flat, conical body, and a cylindrical neck
• A Volumetric Flask is a flat-bottomed bulb with a long neck and its neck has a single ring. it is used for making solutions to a known volume.
• A graduated cylinder is used to measure the volume of an object accurately.
• Test tube is a common piece of glassware consisting of a finger-like length of glass. typically from 10 to 20 mm wide and 50 to 200 mm long.
• Beaker tongs used to carry a beaker after it has been subjected to heat or cold temperatures.
• Crucible tongs used to carry a crucible.
• Test tube holder is a gripping device used to carry test tube.
• Test tube brush is a device use to clean the inside of a test tube.
• Thermometer is used to measure temperature of a substance.
• Medicine dropper is usually glass tubes tapered to a narrow point, and fitted with a rubber bulb at the top and use to transfer liquid in small quantities.
• A test tube rack is used to hold and support test tubes containing chemicals waiting for further operations.
• A glass Stirring rod is used to mix chemicals and liquids. Usually made of solid glass about a thickness of a drinking straw.
• A Retort Stand is a piece of scientific equipment to which clamps can be attached to hold test tubes and other equipment such as a burette.
• C-Clamp is a device used to hold or secure objects to a retort stand.
• Burette is a vertical cylindrical glassware with volumetric graduation on its full length and a precision tap or stopcock on the bottom. ii used to dispense small amount of liquid in experiments for which precision is necessary.
• Clay triangle is used to hold crucible while the crucible is heated.
• Crucible is a ceramic or metal container in which metals or other substances may be melted or subjected to very high temperatures
• Funnel is used to channel liquid or fined grained substances into a containers with small opening
• Mortar and Pestle is a tool used to crush, grind, and mix solid substances
• A spot plate is a ceramic plate with small dwells or depressions built into it. it is used to perform reactions on a very small amount of materials.
• An evaporating dish is a porcelain or ceramic dish used to evaporate excess water or other solvents.
• Petri Dish is a shallow glass or plastic cylindrical lidded the biologist used to culture cells
• Watch glass is a circular, slightly curved piece of glass used as a surface to evaporate liquids or hold solids while being weight or as a cover for a beaker.
• Digital Balance is a highly sensitive lab instrument designed for accurate measurements. their readability has ranged between 0.1mg - 0.01mg.
• Analytical Balances have a draft shield or weighing c chamber to prevent the very small samples from being affected by the air currents.
• A Laboratory Centrifuge is used to separate things. it works on sedimentation principle which causes denser substances to separate from less dense ones.
• A desiccator is a glass or plastic container that can be sealed in which a small amount of desiccant material is placed in the bottom.
