This cylindrical container with a flat bottom has raised markings on its sidewall to indicate measurements in milliliters or ounces on one side while there is a graduation scale on the other side which indicates measurements in liters or pints.īuy Glassco 5 Scientific Glass Beaker Low Form with Pouring Spout 250 ml (Pack of 5 Pcs) online in India at wholesale rates. It also has a pouring spout on top which allows easy pouring of liquid contents inside it without spilling over the sides or onto the table surface while pouring out its contents. This beaker is equipped with clear scale and white markings that are easier to identify and has standard scale line for accurate measurement. The material used in this beaker is of premium quality thick glass, this beaker has low coefficients of thermal expansion, resistant to thermal shock and has high chemical resistance. This cylindrical container with a flat bottom has a uniform wall thickness with marked spots and excellent pouring spout that makes it perfect for the lab usage. This beaker is a multi-purpose lab equipment that can be used for measuring liquids, separating out different substances, doing chemical experiments and much more. These measuring tools are made from premium quality thick glass to ensure durability and good performance. These measuring cups come in different shapes and sizes, so you can get the one that suits your needs. They are designed for accurate measurements, so you can conduct your experiments easily. Most beakers are accurate to within ~10%.GC-229.202.03 - Glassware measuring cups are great for home use as well as for commercial purposes. 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. 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. 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.
