These examples are programmatically compiled from various online sources to illustrate current usage of the word 'beaker.' Any opinions expressed in the examples do not represent those of Merriam-Webster or its editors. Most also have a tiny spout (or beak) to enable pouring, as seen in. 2023 Victoria Kitirattragarn made sure everything is perfect after placing flowers in a Norwegian silver beaker in front of a painting called, Christ Carrying The Cross by, Giovanni Bellini inside the museum’s Titian Room. A beaker is typically a cylindrical container with a flat bottom used in lab equipment. Cora Frazier, The New Yorker, 25 July 2022 There’s also a bearded chef named Sebastian Borg, and on a stainless-steel prep table in front of them sits a little glass beaker of fine saffron powder. 2017 But then researchers noticed that the pockets of their white lab coats were full of mouse droppings, the screens of their phones bore tiny paw prints, and no one could find a test tube smaller than a beaker. Nathaniel Scharping, Discover Magazine, 3 Oct. Eleanor Hildebrandt, Popular Mechanics, 30 June 2021 An iron hydroxide plume in a beaker simulating early Earth conditions. 2022 How to do it:Measure grounds into beaker. Dana Mcmahan, The Courier-Journal, 4 Oct. 2023 Add ingredients to a beaker, then add ice. 2023 The small setup in the middle of the room looked like a combination of a bakery and a lab, with advanced technical equipment, a commercial-grade food dryer, and shelves piled with beakers and cookie sheets. Most beakers are accurate to within ~10%.Recent Examples on the Web Each lab features an incubator (for growing cells), a chemical fume hood and a data storing microscope, along with other traditional lab components, such as beakers. These marks are not intended for obtaining a precise measurement of volume (a graduated cylinder or a volumetric flask would be a more appropriate instrument for such a task), but rather an estimation. For instance, a 250 mL beaker might be marked with lines to indicate 50, 100, 150, 200, and 250 mL of volume. 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. 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. 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. These are sometimes called Berzelius beakers, after Jöns Jacob Berzelius, and are mostly used for titration. "Tall-form" (B) beakers have a height about twice their diameter. Low form beakers are likely to be used in some way when performing a chemical experiment. 2 : a deep widemouthed thin-walled vessel usually with a lip for pouring that is used especially in science laboratories. 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. Definition of beaker 1 : a large drinking cup that has a wide mouth and is sometimes supported on a standard. The common low form with a spout was devised by John Joseph Griffin and is therefore sometimes called a Griffin beaker. Standard or "low-form" (A) beakers typically have a height about 1.4 times the diameter.
