Laboratory Apparatus...


LABORATORY APPARATUS 1. Spatula - to scoop small amounts of a solid substance and to scrape something. 2. Glass Funnel - used to channel liquid or finegrained substances into containers with a small opening. 3. Stirring/Glass Rod - used to mix chemicals and liquids for laboratory purposes 4. Thistle Tube - to add liquid to an existing system of apparatus. 5. Dropper/Pasteur Pipette - used to transport a measured volume of liquid. 6. Volumetric Flask - used to measure one specific volume. 7. Mohr Burette - used to measure the volume of the liquid dispensed. 8. Geissler/Acid Burette - used especially in laboratory procedures for accurate fluid dispensing and measurement. 9. Volumetric Pipette - a tool for measuring precise volumes of a liquid. 10. Serological Pipette - used in the same way as Mohr pipettes except all the solution must be forced out in the receiving container to deliver required volumes. 11. Graduated Cylinder - used to accurately measure the volume of a liquid. 12. Beaker - Used to hold and heat liquids. 13. Florence Flask - used for heating substances that needs to be heated evenly. 14. Erlenmeyer flask - used to heat and store liquids. 15. Iodine Flask - used for the wet chemical analysis 16. Evaporating Dish - used to heat and evaporate liquids. 17. Porcelain Casserole 18. Watch Glass - used to hold solids when being weighed or transported. 19. Ignition Tube - primarily used to hold small quantities of substances which are undergoing direct heating by a Bunsen burner or other heat source. 20. Porcelain Crucible - used to heat small quantities to very high temperatures. 21. Crucible Tong – Used to hold the crucible 22. Distilling Flask - used for distillation processes. 23. Condenser - used in distillation 24. Adapter - a device that connects the condenser and the receiving flask in a distillation process. 25. Test Tube - used by chemists to hold, mix, or heat small quantities of solid or liquid chemicals, especially for qualitative experiments and assays.

26. Test Tube Rack - is used to hold test tubes while reactions happen in them or while they are not needed. 27. Iron Stand – used to hold the iron ring and supports. 28. Iron Ring – used to hold or support beakers during experiments while connected to the iron stand. 29. Tripod – three-legged support equipment used to place above the bunsen burner in the science lab to heat/boil anything. 30. Burette Clamp - used to fasten glassware into place on a ring stand 31. Clay Triangle - used to hold crucibles when they are being heated. 32. Clamp Holder - used to secure an extension-type utility clamp to a support stand (or ring stand) 33. Mortar & Pestle - used to crush solids into powders for experiments, usually to better dissolve the solids. 34. Bunsen Burner - used for heating and exposing items to flame. 35. Alcohol Lamp – Used to heat things. 36. Wing Top/Fish Tail - used to bend glass as it spread out the heat over a larger area, making it more uniform. 37. Wire Gauze - used to spread heat of a burner flame 38. Cork Borer - tool for cutting a hole in a cork or rubber stopper to insert glass tubing. 39. Thermometer - used to take temperature of solids, liquids, and gases. 40. Desiccators - used for preserving moisture-sensitive items. 41. Weighing Bottle - used when you're making up a standard solution. 42. Triangular File - used for many cuts, such as cutting angles less than 90 degrees. 43. Petri Dish - use to culture cells, which can be bacteria, animal, plant, or fungus. 44. Spot Plate – Used for observing small amounts of solids. 45. Test Tube brush - used to easily clean the inside of a test tube. 46. Pinchcock - used to regulate or close a flexible tube, especially in laboratory apparatus. 47. Rubber Aspirator – used for moving air, fluids, etc. by suction 48. Rubber Tubing - is used to connect two openings. 49. Separatory Funnel - used in liquid-liquid extractions to separate (partition) the components of a mixture between two immiscible solvent phases of different densities.

50. Buchner Funnel - used in suction filtration. 51. Filtering Flask - holds the sample isolated from the suction by a layer of filter paper. 52. Triple Beam Balance - used in the laboratory to determine the mass (by weight comparison) of samples. 53. Analytical Balance - measures masses to within 0.0001 g. 54. Hot Plate – Used for heating beakers, Erlenmeyer flasks, hot water baths, and other flat-bottomed containers. 55. pH meter – Used to measure acidity of solutions 56. Wash Bottle – Used for dispensing small quantities of distilled water.
