    • Prepared by:
    • Alcohol Burner Is a source of heat. It is a burner that uses alcohol to produce fire.
    • A stirring rod or stir rod is a piece of laboratory equipment used to mix chemicals and liquids for laboratory purposes. They are usually made of solid glass, about the thickness and slightly longer than a drinking straw, with rounded ends. Like most laboratory glass, stir rods are made of borosilicate (commonly known as pyrex). Stirring Rod
    • Beaker A beaker is a simple container for stirring, mixing and heating liquids commonly used in many laboratories. Beakers are generally cylindrical in shape, with a flat bottom. Most also have a small spout (or "beak") to aid pouring as shown in the picture. Beakers are available in a wide range of sizes, from one milliliter up to several liters.
    • Pipette Bulb Is used to clean the pans of platform balance and get liquid using a pipette.
    • Bunsen Burner A Bunsen burner, named after Robert Bunsen, is a common piece of laboratory equipment that produces a single open gas flame, which is used for heating, sterilization, and combustion.[1][2][3][4][5] The gas can be natural gas (which is mainly methane) or a liquefied petroleum gas, such aspropane, butane, or a mixture of both.
    • The platform balance is a form of equal-arm balance in which two flat platforms are attached to the top side of the beam, one at each end. Such a balance has a rider, or weight, mounted on a bar that has a calibrated scale, is parallel to the beam, and connects the supports of the two platforms. This rider is moved along the bar, its edge marking decimal fractions of the unit weight. Platform Balance
    • Burette A burette (also buret) is a device used in analytical chemistry for the dispensing of variable, measured amounts of a chemical solution. A volumetricburette delivers measured volumes of liquid. Piston burettes are similar to syringes, but with precision bore and plunger. Piston burettes may be manually operated or may be motorized.[1] A weight burette delivers measured weights of liquid.[2]
    • Reagent bottles, also known as media bottles or graduated bottles, are containers made of glass, plastic, borosilicate or related substances, and topped by special caps or stoppers and are intended to contain chemicals in liquid or powder form for laboratories and stored in cabinets or on shelves. Some reagent bottles are tinted amber (actinic), brown or red in order to protect light-sensitive chemical compounds from visible light, ultraviolet and infrared radiation which may alter or break them down. The bottles are called "graduated" when they have marks on the sides indicating the approximate (rarely exact) amount of liquid at a given level within the container. A reagent bottle is a type of laboratory glassware. The term "reagent" refers to a substance that is part of a chemical reaction (or an ingredient of which), and "media" is the plural form of "medium" which refers to the liquid or gas which a reaction happens within, or is a processing chemical tool such as (for example) a flux. Reagent Bottle
    • Ceramic Square Supports hot apparatus to prevent breakage.
    • Rubber Stopper Supports thermometer and covers the opening of narrow-mouthed containers.
    • Clay Triangle A clay triangle is a piece of laboratory apparatus that is used to support items being heated by a bunsen burner or other heat source. It is made of wires strung in an equilateral triangle on which are strung hollow pipeclay or ceramic tubes. The triangle is usually supported on a tripod or iron ring. Unlike wire gauze, which primarily supports glassware such as beakers, laboratory flasks, or evaporating basins and provides indirect heat transfer, the pipeclay triangle normally supports a crucible and allows the flame to heat it directly.
    • Rubber Tubing Connects a bunsen burner to a gas outlet
    • Crucible Tongs Crucible tongs are large pincers made of welded steel that are used to grasp and take a hot crucible out of a fire or furnace, or to move a crucible from one location to another.
    • Test Tube Brush A test tube brush is a brush to clean test tubes. A long slender brush with nylon bristles. The bristles encircle the brush on all sides. Care needs to be taken or you can break the bottom out af the test tube you are trying to clean. These are very handy in any science environment.
    • Double Burette Clamp A double burette clamp is a laboratory apparatus that is used to hold either a single burette or two burettes at the same time. They normally have two single burette clamps mounted approximately 2 inches apart on a cross bar to hold two burettes at the same time.
    • Erlenmeyers are used in chemistry labs for titration, e.g. for pH, as they can be held and the contents mixed single-handed leaving the other hand free to addreagent.[4] Erlenmeyer flasks are extremely useful in the lab setting for stirring the contents by hand by swirling the flask, as the tapered neck prevents spillage of the contents. Erlenmeyer Flask
    • Test Tube holder It is a clamp that holds a test tube -- for instance to hold a test tube while heating it without getting burned. It is made from a thick piece of metal wire that is shaped into a spring-loaded clamp to securely hold a test tube.
    • Test Tube Holder The function of a test tube holder is to hold the test tubes and keep them in a secure position without being held by hand. A test tube is used to hold small amounts of solution.
    • Evaporating Dish An evaporating dish is a piece of laboratory glassware used for the evaporation of solids and supernatant fluids,[note 1] and sometimes to their melting point. Evaporating dishes are used to evaporate excess solvents, most commonly water - to produce a concentrated solution or a solid precipitate of the dissolved substance.
    • Test tube rack The function of a test tube rack is to observe the chemical substance present in different test tubes. The test tube rack is also referred to as a test tube holder.
    • Flame Loop Is used to hold chemicals during flame test.
    • A thermometer (from the Greek θερμός, thermos, meaning "hot" and μἐτρον, metron, "measure") is a device that measures temperature or temperature gradient using a variety of different principles.[1] A thermometer has two important elements: the temperature sensor (e.g. the bulb on a mercury-in- glass thermometer) in which some physical change occurs with temperature, plus some means of converting this physical change into a numerical value (e.g. the visible scale that is marked on a mercury-in-glass thermometer). Thermometer
    • A Florence flask (also known as a boiling flask) is a type of flask used as an item of laboratory glassware. It is used as a container to hold liquids. A Florence flask has a round bottom with a single long neck. It is designed for uniform heating and ease of swirling; it is produced in a number of different glass thicknesses to stand different types of use. They are often made of borosilicate glass to prevent cracks or defacing of the glass. The flask is named after Florence, Italy. Traditional Florence flasks typically do not have a ground glass joint on their rather longer necks but typically have a slight lip or flange around the tip of the neck. A common size of a Florence flask is 1 litre.[1] Florence Flask
    • Triple Beam Balance The Triple Beam Balance is a typical mechanical balance. It has a beam which is supported by a fulcrum. On one side is a pan on which the object is placed. On the other side, the beam is split into three parallel beams , each supporting one weight. In measuring the weight of an object, rather than adding additional weights, each of the three weights can be slid along the beam to increase their lever arm. It works just like a tetter-totter. If you have two people of unequal weight, the heavier person sits closer to the fulcrum to decrease their lever arm.
    • Forceps or forcipes are a handheld, hinged instrument used for grasping and holding objects. Forceps are used when fingers are too large to grasp small objects or when many objects need to be held at one time while the hands are used to perform a task. The term 'forceps' is used almost exclusively within the medical field. Outside medicine, people usually refer to forceps as tweezers, tongs, pliers, clips or clamps. 'Forceps' can be used as both the singular and plural form of the word. (Example: "I need a forceps.") Also, it is not referred to as a "pair" as one refers to a "pair of scissors". Etymologically, the word derives from the Latin forca, meaning a snare or trap. Mechanically, forceps employ the principle of the lever to grasp and apply pressure. Forceps
    • Tripod A tripod lab equipment is a three-legged equipment that is usually used as a platform to hold various flasks, beakers and other glassware during experiments. It is made of a strong material such as aluminium.
    • A funnel is a pipe with a wide mouth, good for feeding, often conical mouth and a narrow stem. It is used to channel liquid or fine-grained substances into containers with a small opening. Without a funnel, spillage would occur. Funnels are usually made of stainless steel, aluminium, glass, or plastic. The material used in its construction should be sturdy enough to withstand the weight of the substance being transferred, and it should not react with the substance. For this reason, stainless steel or glass are useful in transferring diesel, while plastic funnels are useful in the kitchen. Sometimes disposable paper funnels are used in cases where it would be difficult to adequately clean the funnel afterward (for example, in adding motor oil to a car). Dropper funnels, also called dropping funnels or tap funnels, have a tapto allow the controlled release of a liquid. Funnel
    • A volumetric flask (measuring flask or graduated flask) is a piece of laboratory glassware, a type of laboratory flask, calibrated to contain a precise volume at a particular temperature. Volumetric flasks are used for precise dilutions and preparation of standard solutions. These flasks are usually pear-shaped, with a flat bottom, and made of glass or plastic. The flask's mouth is either furnished with a plastic snap/screw cap or fitted with a joint to accommodate a PTFE or glass stopper. Volumetric flask
    • A graduated cylinder, measuring cylinder or mixing cylinder is a piece of laboratory equipment used to measure the volume of a liquid. Graduated cylinders are generally more accurate and precise than laboratory flasks and beakers. However, they are less accurate and precise than volumetric glassware, such as a volumetric flask or volumetric pipette. For these reasons, graduated cylinders should not be used to perform volumetric analysis.[1] Graduated cylinders are sometimes used to indirectly measure the volume of a solid by measuring the displacement of a liquid. Graduated Cylinder
    • 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. Wash bottles are sealed with a screw-top lid. When hand pressure is applied to the bottle, the liquid inside becomes pressurized and is forced out of the nozzle into a narrow stream of liquid. Most wash bottles are made up of polyethylene, which is a flexible solvent- resistant petroleum-based plastic. Most bottles contain an internal dip tube allowing upright use. Wash Bottles
    • Iron Ring An iron ring, sometimes called an iron support ring, [1] is used in chemistry labs to stabilize flasks mounted to a ring stand.[2] Some iron rings include a clamp, while others require a utility clamp to attach to a ring stand.
    • Watch Glass A watch glass is a circular, slightly convex-concave piece of glass used in chemistry as a surface to evaporate a liquid, to hold solids while being weighed, or as a cover for a beaker. The latter use is generally applied to prevent dust or other particles entering the beaker; the watch glass does not completely seal the beaker, and so gas exchanges still occur. When used as an evaporation surface, a watch glass allows closer observation of precipitates or crystallisation, and can be placed on a surface of contrasting colour to improve the visibility overall. Watch glasses are also sometimes used to cover a glass of whisky, to concentrate the aromas in the glass, and to prevent spills when the whisky is swirled.[citation needed]
    • Iron Stand Supports the iron ring or clamp
    • Wire gauze used for supporting beakers and flasks when they are being heated with a Bunsen Burner . They are constructed of a metal mesh screen that contains a ceramic fiber circle in the center that can withstand extremely high temperatures.
    • Dropper Pipette Used to transfer small amounts of liquids to another container
    • Spot Plate Reaction vessel used for small amounts of substances, especially when using litmus paper
    • The mortar is a bowl, typically made of hard wood, ceramic or stone. The pestle is a heavy club-shaped object, the end of which is used for crushing and grinding. The substance to be ground is placed in the mortar and ground, crushed or mixed with the pestle. Sometimes referred to as an "Apothecary Grinder" by individuals unfamiliar with its use, the proper historical name is "mortar and pestle". The mortar and pestle is usually utilised when cooking and when crushing ingredients for a certain drug in pharmacies. It can also be used in masonry and in other types of construction. Mortar and Pestle
    • Spatula Used for getting solid chemicals from reagent bottles.
    • A crucible is a ceramic container capable of withstanding extreme temperatures, whilst the cover is designed to prevent heat escaping from the crucible itself. Crucibles are used for a range of purposes, and are particularly common amongst chemists for the chemical analysis of various substances Crucible and Cover
    • Fish Tail Fish Tail is a Laboratory apparatus inserted to a Bunsen or a gas burner to spread the flame.
    • A bell jar is a piece of laboratory equipment used to contain vacuums.[1] It can be similar in shape to a bell, and can be manufactured out of a variety of materials (ranging from glass to different types of metals). A bell jar is placed on a base which is vented to a hose fitting, which can be connected via a hose to a vacuum pump. By pumping the air out of the bell jar, a vacuum is formed. Bell Jar
    • Glass tubing delivery tubes Used to make droppers for capillary tubes.
    • Desiccator Used for removing the moisture from specimens
    • Syringe Is used for sucking and expelling liquid in fine stream
    • Measuring pipettes Measures exact volume of liquids
    • Transfer pipette Used to transfer liquids
