CHEMISTRY What is the first thing that comes to you when you hear/read the word above?  CHEMISTRY the branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances.  Organic Chemistry Biochemistry deals with the study of carbon containing deals with the study of the molecules of compounds. life such as amino acid, carbohydrates, lipids and nucleic acids. Inorganic CHEMISTRY is the study of matter and the Analytical changes it undergoes Chemistry Chemistry deals with the determination of the composition deals with the study of all non-carbon containing of the sample and all other transformations compounds. It also includes simple carbon involved in the analytical process. containing compounds such as carbonates, Physical bicarbonates, gases containing carbon such as carbon monoxide and carbon dioxide Chemistry deals with the study of how matter behaves on a molecular and atomic level and how chemical reactions occur. Common Laboratory Apparatus and Instruments Apparatus for Physical Property Analysis Analytical Balance- designed to measure small mass below the milligram range. Watch Glass – A circular concave piece of glass can be used as a surface to evaporate a liquid, to hold solids while being weighed, for heating a small amount of substance and as a cover for a beaker.  Apparatus for Physical Property Analysis Petri Dish – A Petri dish is a shallow transparent lidded dish that biologists use to hold growth medium in which cells can be cultured such as bacteria, fungi and small mosses. Crucible – A ceramic or metal container in which metals or other substances may be melted or subjected to very high temperatures.  Apparatus for Physical Property Analysis Desiccators – Are sealable enclosures containing desiccants at its bottom enclosure in order to preserve moisture-sensitive items. Hydrometers – A hydrometer is an instrument used for measuring the relative density of liquids based on the concept of buoyancy.  Apparatus for Physical Property Analysis Magnetic Stirrers – A magnetic stirrer or magnetic mixer is a laboratory device that employs a rotating magnetic field to cause a stir bar immersed in a liquid to spin very quickly, thus stirring it. Filter paper – Generally, filter papers are used with laboratory techniques such as gravity or vacuum filtration  Apparatus for Physical Property Analysis Separatory Funnel – A Separatory funnel, also known as a separation funnel, separating funnel, is a piece of laboratory glassware used in liquid-liquid extractions to separate the components of a mixture into two immiscible solvent phases of different densities. Centrifuge – A centrifuge is a device that uses centrifugal force to separate various components of a fluid.  Apparatus for Physical Property Analysis Laboratory Fractionating Columns – Fractional distillation involves repeated evaporation–condensation steps before the distillate is actually collected. Apparatus for Physical Property Analysis Heating Equipment – Wet chemical analysis rely on reactions and depending on procedure might be best done on temperatures higher than the room temperature Hot Plates – A portable self-contained tabletop appliance that features one or more electric heating elements or gas burners. Bunsen Burners – a kind of gas burner used as laboratory equipment; it produces a single open gas flame, and is used for heating, sterilization, and combustion. Apparatus for Wet Chemical Analysis Laboratory Ovens – are electrical devices which use dry heat to sterilize. Generally, they use a thermostat to control the temperature. Test Tubes – Test tubes are widely used by chemists to handle chemicals, especially for qualitative experiments and assays.  Apparatus for Wet Chemical Analysis Beakers – A beaker is a cylindrical container used to store, mix and heat liquids in laboratories. Most are made of glass, but other non-corrosive materials, such as metal and heat-resistant plastic, are also used. Graduated Cylinder – Graduated cylinders are often used to measure the volume of a liquid. It is more accurate and precise than laboratory flasks and beakers, but should not be used to perform volumetric analysis especially if the measurement requires very high precision and of small volume amounts. Apparatus for Wet Chemical Analysis Pipet – A pipette (sometimes spelled pipet) is a laboratory tool is used to transport a high accuracy measurement of liquid volumes. Volumetric Flask – A type of laboratory flask, calibrated to contain a precise volume at a certain temperature. Volumetric flasks are used for precise dilutions and preparation of standard solutions. Apparatus for Wet Chemical Analysis Erlenmeyer Flask – a type of laboratory flask which features a flat bottom, a conical body, and a cylindrical neck. Florence Flask – a type of flask used as an item of laboratory glassware. It is used as a container to hold liquids. It has a round body, a long neck, and often a flat bottom designed for uniform heating, boiling, distillation and ease of swirling. Apparatus for Wet Chemical Analysis Burette – A circular concave piece of glass used in chemistry that has many uses. It can be used as a surface to evaporate a liquid, to hold solids while being weighed, for heating a small amount of substance and as a cover for a beaker.
