1. GLASSWARE USED IN ANALYTICAL ANALYSIS

2. ACID BURETTE Used to accurately measure and dispense acid liquid . A burette is a long glass tube that has markings on it for measurement. It also has a stopcock at the bottom of it that controls how much liquid is released at a time. 2

3. BASE BURETTE used to dispense an alkaline liquid into a solution 3

4. Product overview 4

5. SEROLOGICAL PIPETTE used in the laboratory for  transferring milliliter volumes of liquid, from less than 1 ml to up to 50 ml . The pipettes can be sterile, plastic, and disposable or sterilizable, glass and reusable. 5

6. MOHR PIPETTE also known as a graduated pipette, is a type of pipette used  to measure the volume of the liquid dispensed , although not as accurately as a volumetric pipette. 6

7. VOLUMETRIC FLASK used for  measuring accurate volumes of liquid materials for laboratory experiments . They are favored when available because they are more accurate than graduated cylinders and beakers 7

8. WASH BOTTLE A wash bottle is a squeeze bottle with a nozzle, used  to rinse various pieces of laboratory glassware , such as test tubes and round bottom flasks. To clean laboratory glassware and other equipment.

9. POLICEMAN It is a piece of rubber tubing fitted to the end of a glass rod. It is used to loosen from the walls of the containing vessel adhering particles that are not removable by steam of water from the wash bottle. 9

10. CRUCIBLE a cup-shaped container used in a laboratory to heat chemical compounds to high temperatures or melt metals. Crucibles are made from materials with a higher melting point than the materials being melted, and are designed to withstand extremely high temperatures 10

11. GOOCH CRUCIBLE A porcelain Gooch crucible is a type of laboratory container used for the filtration and analysis of fine powders or other small particle samples. It is typically made of porcelain, a type of ceramic material that is able to withstand high temperatures and chemical corrosion. 11

12. FRITTED GLASS CRUCIBLE This porous glass body can also be called a frit. Applications in laboratory glassware include use in fritted glass filter items, scrubbers, or spargers. Other laboratory applications of fritted glass include packing in chromatography columns and resin beds for special chemical synthesis. 12

13. DESICCATOR A desiccator vacuum is a laboratory apparatus used to store and preserve moisture-sensitive materials. It typically consists of a clear, airtight container and a source of vacuum, such as a pump or a vacuum valve, to remove the air and create a low-humidity environment inside the container. The materials being stored are placed on a shelf inside the container, and the vacuum is applied to remove any air and moisture that might cause degradation of the materials over time. Desiccator vacuums are commonly used in chemical, pharmaceutical, and scientific research to store samples, reagents, and other sensitive materials. They help to prolong the shelf life and maintain the quality of the materials being stored. 13
