Question Answer
beaker This glassware is used as a container for mixing, observing and measuring (rough estimate) the volume of liquids. It is cylindrical in shape, with a flat bottom.
Florence flask This glassware is used as a container to hold liquids. It has a round body with a flat bottom and a single long neck. It is also known as a "boiling flask". It is named after Florence, Italy.
Erlenmeyer flask This glassware is named after the German chemist Emil Erlenmeyer. It is used as container for mixing contents by swirling. It has a flat bottom, a conical body, and a cylindrical neck.
evaporating dish This is a Porcelain that is used for the evaporation of solutions and liquids. It can withstand high heat and is sometimes made of glass.
funnel This is a pipe with a wide, often with a conical mouth and a narrow stem. It is used to channel liquid or fine-grained substances into containers with a small opening. It is sometimes made of glass or stainless steel.
wire gauze This is used to support a container (such as a beaker or flask) during heating. It is used to help spread the flame (and heat) out evenly over the container.
triple beam balance This balance is used to measure the mass of an object very precisely with a reading error of 0.05 gram. It has a pan and three sliders on three beams.
microscope This is an instrument used to see objects that are too small for the naked eye. It uses lenses and light to enlarge images of very small objects, such as mineral samples or animal or plant cells, It typically magnified several hundred times.
graduated cylinder This glassware is a measuring cylinder or mixing cylinder. It is used to measure the volume of a liquid. It has a narrow cylindrical shape.
tripod This is a three-legged equipment used as a platform to hold and support glassware, such as beakers and flasks, during experiments.
Bunsen burner This is a laboratory equipment that produces a single open gas flame. It is used for heating, sterilization, and combustion. The gas can be natural gas (which is mainly methane) or a liquefied petroleum gas, such as propane, butane, or a mixture of both. It is named after Robert Bunsen.
magnifying glass This is used to produce a magnified image of an object.
pipette This glassware allows extremely accurate measurement of a volume of solution. It has a large bulb with a long narrow portion above with a single graduation mark as it is calibrated for a single volume.
thistle tube This glassware is used by chemists to add liquid to an existing system or apparatus. consists of a shaft of tube, with a reservoir and funnel-like section at the top.
stirring rod This glassware is used to mix chemicals and liquids for laboratory purposes. It has the thickness of a drinking straw but slightly longer, with a rounded end
thermometer This is a device that measures temperature.
spring balance This device measures weight. It consists of a spring fixed at one end with a hook to attach an object at the other.
electronic scale This is an electronic device used to find accurate measurements of weight digitally.
pipette bulb This is used to draw liquid up into a pipette.
iron stand This is used to support an iron ring, or iron clamp.
alcohol lamp This is used to produce an open flame. The flame is cooler than that of a Bunsen burner. It has a small jar with a special lid that holds a round cotton wick. It can be made from brass, glass, stainless steel or aluminium
test tube This glassware is used to hold, mix, or heat small quantities of solid or liquid chemicals. It has a round bottom and straight sides that minimize mass loss when pouring, easier to clean, and allows convenient monitoring of the contents. It is sometimes made of plastic.
test tube brush This is used to clean test tubes.
test tube holder This is used to distance a person from potentially dangerous tasks when using chemicals in test tube.
test tube rack This is used to hold, store, and support test tubes so that they do not roll away, tip over, break, or strike one another.
crucible tongs This is used to handle hot objects such as crucibles, and evaporating dishes. It is made of stainless or brass.
mortar and pestle This is used for crushing, grinding and mixing substances into paste or powder.
glass slide This is used to hold objects for examination under a microscope.
clay triangle This is used to support items being heated by a Bunsen burner or another heat source. It is made of wires strung in an equilateral triangle on which are strung hollow ceramic tubes.
Petri dish This glassware is used to culture cells – such as bacteria – or small mosses. It is named after the German bacteriologist Julius Richard Petri. It is a shallow cylindrical glass or plastic lidded dish.
