![]() ![]() ![]() A beaker may have a separate lid or it may come with a built-in lid.īeakers are available in different shapes and sizes. They have a flat bottom and wide top which allows them to be used on various types of laboratory equipment. For example, if you were heating water in a glass beaker on a hot plate, the sides of the glass would expand due to thermal expansion if you were cooling water in an aluminum beaker with ice cubes floating in it (a common experiment), then these objects would cause convection currents within your liquid as they heated up and cooled down respectively.īeakers are used to hold liquids, solutions, solids, powders and gases. Beakers are often used to heat or cool liquids, depending on the material and purpose of the beaker.Beakers are used to measure and mix liquids.Beakers are very versatile and can be used as containers for other things as well, like food or plants.īeakers are commonly used in science experiments because they're easy to clean and they're available at most stores that sell laboratory supplies. Beakers are often used to hold chemicals, and some beakers can also measure the volume of liquid. You can also hold onto this handle while filling it up with other materials like sand or soil before mixing them together! How do you use a beaker?Ī beaker is a vessel used to hold liquids in the laboratory. ![]() If you're working with a small amount of liquid or want to be safe while holding hot liquids, then it's best to use the handle on your beaker. The most common way is to use a measuring cup, but you may also use a graduated cylinder or pipette if you want to get more accurate measurements. You can measure a liquid in a beaker using several different tools. You can use a graduated cylinder for measuring instead if you're working with large amounts of liquid, but graduated cylinders aren't as useful for mixing or heating small quantities of liquid.īeakers are great for mixing two different ingredients together because they don't spill out easily like bowls do when mixing things up! They're also good for heating up water without spilling too much at once onto your countertop (or yourself!).īeaker-chemistry How do you measure liquid in a beaker? Beakers can also be used to measure liquids they have measurement markings on them so you can measure how much liquid is in there. The flat bottom allows the beaker to stand on its own and make it easier to pour the liquid out of. Here's everything you need to know about these handy tools! What is a beaker in science?Ī beaker is a glass container with a flat bottom that is used to hold liquids. Beakers are also commonly used by chemists because they are easy to clean and sanitize after each use. You can use beakers to measure out your ingredients, mix them together and observe what happens during the reaction. They come in all shapes and sizes, but they're all designed to hold a certain amount of liquid at a time. A beaker is an important piece of lab equipment that helps scientists study chemical reactions.īeakers are an important piece of lab equipment that scientists use to study reactions.Thank you to Lee Liu, the senior graduate student in the Ni group from Harvard University, for his explanation of his research and its impact on future studies. Lee Liu, the senior graduate student on the project, describes this as “stripping a chemical reaction down to the bare essentials: two atoms, and something to add or remove energy - in this case a laser photon.” He also points out that this work isn’t only for the microscopic insight of chemical reactions, but also “it is an important first step to making ‘custom’ molecules that could serve as qubits (building blocks of a quantum computer).” al., the researchers begin the experiment by picking out a single sodium atom and a single cesium atom from a hot atomic vapor with tweezers made from lasers - a technique known as optical tweezers - and bring them together to form an optical “beaker”, in which the two atoms can now react. That means that there are a variety of local differences between each given individual molecular reaction that are ignored or simply not even observable. For comparison, while every chemistry class in high school is taught using nearly a trillion trillion atoms (~one mole), the Ni group is using the very minimum number - precisely two.Ĭhemistry has traditionally been studied in a controlled, but ensemble averaged fashion. The group’s goal is to better understand the minimal requirements and exact properties of chemical reactions. Ni’s group at Harvard have taken this idea a step further by building molecules one atom at a time. Typically, if you want to understand the foundation of something, building from the ground up sounds like a sensible approach. ![]()
