[Wikipedia excerpt:  ‘….In laboratory equipment, a ‘B’ 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. ‘B’ are available in a wide range of sizes, from one milliliter up to several liters. A ‘B’ is distinguished from a flask by having straight rather than sloping sides. The exception to this definition is a slightly conical-sided ‘B’ called a Philips ‘B’. The ‘B’ shape in general drinkware is similar. ‘B’ are commonly made of glass (today usually borosilicate glass, but can also be in metal (such as stainless steel or aluminum) or certain plastics (notably polythene, polypropylene, PTFE). A common use for polypropylene ‘B’ is gamma spectral analysis of liquid and solid samples….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. Low form beakers are likely to be used in some way when performing a chemical experiment. “Tall-form” (B) ‘B’ have a height about twice their diameter. These are sometimes called Berzelius ‘B’ and are mostly used for titration. Flat ‘B’ (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 ‘B’ usually do not have a flat scale. The presence of a spout means that the ‘B’ cannot have a lid. However, when in use, ‘B’ may be covered by a watch glass to prevent contamination or loss of the contents, but allowing venting via the spout. Alternatively, a ‘B’ may be covered with another larger ‘B’ that has been inverted, though a watch glass is preferable. ‘B’ are often graduated, that is, marked on the side with lines indicating the volume contained. For instance, a 250 mL beaker might be marked with lines to indicate 50, 100, 150, 200, and 250 mL of volume. 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. Most ‘B’ are accurate….’]
