Organic Chemistry Laboratory

• Pipette - used to transport a measured volume of liquid. It is also used to extract or deliver small amounts of liquid.
• There are two types of pipette: Volumetric pipette and graduated pipette
• Beakers - used as containers. The markings are not necessarily accurate, they are rough estimates of the liquid volume
• Erlenmeyer flask - used as reaction vessels, particularly in titrations.
• Volumetric flask - used to measure and store solutions with a high degree of accuracy.
• Volumetric flask - These devices are often used when solutions containing dissolved solids of known concentration are needed.
• Volumetric flask - This glassware generally possesses a marking near the top that indicates the level at which the volume of the liquid is equal to the volume written on the outside of the glassware.
• Graduated cylinders - used to transfer liquids with a moderate degree of accuracy.
• Stirring rod - used to mix chemicals and liquids for laboratory purposes.
• Dropper - used to transfer small quantities of liquid.
• Burette - used to dispense and measure a variable amount of a chemical solution.
• Funnel - A tube or pipe that is wide at the top and narrow at the bottom, used for guiding liquid or powder into a small opening.
• Test tube - a common piece of laboratory glassware consisting of a finger-like length of glass or clear plastic tubing, open at the top and closed at the bottom
• Watch Glass - a circular concave piece of glass used in chemistry 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.
• Evaporating Dish - a tool used in labs to separate liquids and solids from a solution by allowing the water to evaporate off into the air.
• Crucible - a small container that is used to hold reactants during heating at higher temperatures.
• Reagent Bottle - 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.
• Thermometer - devices for measuring temperature
• Separatory funnel - used to separate immiscible liquids.
• Distilling Flask - A glass usually round-bottomed flask for holding a substance to be distilled.
• Condenser - a piece of laboratory glassware used to cool hot vapors or liquids.
• condenser - usually consists of a large glass tube containing a smaller glass tube running its entire length, within which the hot fluids pass.
• mortar and pestle - a tool used to grind and mix substances.
• pestle - a heavy small bat, made from porcelain, wood, or other materials, whose rounded end is used for pounding and grinding.
• mortar - a bowl, which can be made from porcelain, wood, carved stone or other materials.
• Burette Clamp - scientific equipment which used specifically to hold and secure a burette on a stand, so that a burette is fixed and more convenient for the experiment
• Rubber Aspirator - main purpose is for moving air or liquids. It does this by suction that allows fluid to flow through a tube
• Test tube holder - designed to hold test tubes
• Test tube racks - used for holding test tubes upright when they contain chemicals, and also hold test tubes upside down to dry
• Spatula - a small stainless steel utensils, used for scraping, transferring, or applying powders and paste like chemicals.
• Rubber Stopper - used to prevent a gas or liquid from escaping its container during a scientific experiment.
• Rubber stoppers - can also prevent the contamination of samples by protecting the contents of laboratory glassware from air.
• Rubber stopper - allows experimenters to shake or mix solutions without spilling them.
• Crucible Tongs - 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
• Wash bottle - a squeeze bottle with a nozzle, used to rinse various pieces of laboratory glassware, such as test tubes and round bottom flasks.
• wire gauze - used to place under the container holding the liquid, that is being heated by the Bunsen Burner, so that the container doesn’t have direct contact with the flame.
• Clay Triangles - placed on a ring attached to a ring stand as a support for a funnel, crucible, or evaporating dish.
• Iron stand - A metal rod attached to a heavy metal base. The heavy base keeps the stand stable, and the vertical metal rod allows for easy height adjustment of the iron ring/clamp.
• iron ring - holds glassware such as a funnel or other objects, like the wire gauze or clay triangle for heating with a Bunsen Burner.
• iron clamp - a piece of laboratory equipment used to hold things and is placed in an iron stand to elevate other equipment
