Griffin Beakers are the most often used, with purposes varying from preparing solutions and decanting supernatant fluids to holding waste fluids prior to disposal to performing simple reactions. Essentially, low form beakers are likely to be used in some way when performing just about any chemical experiment. Flat beakers are often called crystallizers because most are used to perform crystallization.
However, they are also often used as a vessel for use in hot-bath heating. These beakers usually do not have a flat scale. There are two classes of accuracy for reading graduated cylinders. Class A has double the accuracy of Class B. Cylinders can have single or double scales.
Single scales allow the volume to be read from top to bottom filling volume , while double scale cylinders allow reading for filling and pouring reverse scale. To read the volume accurately, the observation must be at an eye level to be read at the bottom of the meniscus of the liquid level.
Beakers are often graduated or marked on the side with lines indicating the contained volume. For instance, a mL beaker might be marked with lines to indicate 50, , , , and 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.
The presence of a spout means that the beaker cannot have a lid. When it comes to standard lab equipment in your laboratory, measuring cylinders and beakers are the most common yet useful equipment pieces in your experiments.
Each piece of equipment, the graduated measuring cylinder, and beaker serves its own purpose with a specific function in the lab. Measuring cylinders are more accurate at reading the liquid's volumes, whereas Glass Beakers are better for stirring and mixing liquids and solids in liquids.
They are both made from the same borosilicate glass, while Glass beakers are more rigid and less brittle and have higher heat resistance, which is essential when melting and mixing solid to liquids and boiling liquids. Most common laboratory glassware as lab equipment is easy to clean and autoclave, and can be reused again and again with the right care, and can be used to measure, mix, boil, crystallize, evaporate, dissolve, store, and much more.
Let's Talk about the most common lab equipment, the glass beaker, first. Laboratory beakers are commonly used for stirring, mixing and heating liquids found in laboratory settings.
The capacity of a glass beaker ranges from 10ml to 1L. They were primarily used to measure the volume of an object or amount of liquid; as the name indicates, it's a glass cylinder with marks along the side similar to those on a measuring cup.
The volume is accurately read by looking at the top of the fluid from the side angle and reading the glass's mark from the lowest portion meniscus liquid lens of the liquid.

You may be mistaken to use markings for accurate measurements, but graduated cylinders or flasks are used for accurate measurements. Chemicals can be quite abrasive, and when using glassware, it is important to wash off any residue to help protect the glass, quality, and standards.
