These marks are not intended for obtaining a precise measurement of volume (a volumetric flask would be a more appropriate instrument for such a task), but rather an estimation. Alternatively, a beaker may be covered with another larger beaker that has been inverted, though a watch glass is preferable.īeakers are often graduated, that is, marked on the side with lines indicating the volume contained. beaker in Chemistry topic beakerbeaker /bik -r/ noun countable 1 British EnglishDFU a drinking cup with straight sides and no handle, usually made of. However, when in use, beakers may be covered by a watch glass to prevent contamination or loss of the contents, but allowing venting via the spout. The presence of a spout means that the beaker cannot have a lid.

These beakers usually do not have a flat scale. “Tall-form” (B) beakers have a height about twice their diameter. These are sometimes called Berzelius beakers and are mostly used for titration. Flat beakers (C) are often called “crystallizers” because most are used to perform crystallization, but they are also often used as a vessel for use in hot-bath heating. With the lifelike physics simulation, you can shake it up, light up a match, or even tilt your device to. Low form beakers are likely to be used in some way when performing a chemical experiment. where you can explore chemistry anywhere, anytime. Standard or “low-form” (A) beakers typically have a height about 1.4 times the diameter. The common low form with a spout was devised by John Joseph Griffin and is therefore sometimes called a Griffin beaker. These are the most universal character and are used for various purposes-from preparing solutions and decanting supernatant fluids to holding waste fluids prior to disposal to performing simple reactions. A common use for polypropylene beakers is gamma spectral analysis of liquid and solid samples. BEAKER turns your device into a virtual lab to experiment with 150+ chemicals. The beaker shape in general drinkware is similar.īeakers are commonly made of glass (today usually borosilicate glass). The exception to this definition is a slightly conical-sided beaker called a Philips beaker. A beaker is distinguished from a flask by having straight rather than sloping sides. Beakers are available in a wide range of sizes, from one milliliter up to several liters. The Beaker models versatility in 90 of the waves we face everyday has made it an ideal choice for someone trying to get the most use out of one board in. Definition of beaker 1 : a large drinking cup that has a wide mouth and is sometimes supported on a standard. In laboratory equipment, a beaker is generally a cylindrical container with a flat bottom. Most also have a small spout (or “beak”) to aid pouring, as shown in the picture. Stationary – Handcrafts – Drawing Equipment.Microscope – Preparations (Environment).Packages of Compulsory Secondary Exercises.They are generally made of a thin, heat resistant glass like Pyrex, which are available in an assortment of sizes too suit different laboratory needs.

A beaker is a fancy mayonnaise jar used for measuring and mixing of chemical solutions in laboratories. Carolina offers the highest quality kits for a hands-on approach within AP Chemistry classrooms.They are used as distillation receiving containers, to hold different layers in an extraction. On the various shelves were set items of laboratory equipment: retorts, beakers, distilling tubes and burners. Beakers are a general-purpose item in the organic chem labs.Cold and shaken from the journey, thick with sediment and drunk from a plastic beaker, it tasted like medicine.She took his beaker away and placed it on the balcony wall.At one point we see a homunculus encased in a glass beaker, exactly like a test-tube baby.Representative goblets and beakers of late sixteenth century and seventeenth century date are illustrated in Figures 3.50 and 3.51.A beaker and a flask steamed on the bench beside him as he spoke.One balanced a beaker of steaming coffee on a nearby terminal before moving on bearing a full tray. ![]() From Longman Dictionary of Contemporary English beaker bea‧ker / ˈbiːkə $ -ər / noun 1 British English DFU a drinking cup with straight sides and no handle, usually made of plastic 2 HC a glass cup with straight sides that is used in chemistry for measuring and heating liquids Examples from the Corpus beaker
