Schematic of zone electrophoresis apparatus Superior gear that is designed for lab scientists, medical workers, students and school pupils can be used for different purposes. BHS Chemistry Lab Equipment Adapted from presentations by Stephen L. Cotton, Charles Page High School and Mrs. Parris, Galax High School 2. They are wider and bigger than regular test tubes, and they have a flat bottom. 7.Beakers These pieces of laboratory equipment are used for chemical tests and in medical organisations. Here’s a spelling tip: often, when a word ends in -us, the plural ending changes to i — “alumnus/alumni,” “focus/foci.” However, apparatus is part of the group that doesn't change — words like “virus/viruses” or “census/censuses.” This means the plural is either apparatus or apparatuses, though the latter is more common. Filtration, the process in which solid particles in a liquid or gaseous fluid are removed by the use of a filter medium that permits the fluid to pass through but retains the solid particles. "An apparatus designed to measure the elongation or contraction of a spring when attached to two scale-pans,… Simple Balance An image of a balance used in chemistry labs to measure small objects. The average length of a spatula tool is 7 inches. For many years, the country had been buried under the apparatus of the regime. Titration equipment. In this page you will learn about lab equipment and its uses. Different activities, different apparatuses. Used for holding chemicals during heating to very high temperatures. Such common laboratory apparatus are popular in many homes. Whenever you have to measure a particular amount of liquid (and the volume matters a lot), you should choose the special volumetric flask that is designed to hold only a precise amount and no more. Firstly, you need to reread the safety protocol before working. Every laboratory requires way more than 20 pieces of equipment. But they are transparent and make it easy to view what you have poured into each one, transport liquids, and sometimes even measure chemicals. Many contemporary tongs can even hold beakers. 1. variable noun. capillary action - the spontaneous floe of liquid into a narrow tube or porous material. a group or combination of instruments, machinery, tools, materials, etc., having a particular function or intended for a specific use: Our town has excellent fire-fighting apparatus.
