Things You'll Need. The Names of Chemistry Flasks. Flasks and beakers do share some characteristics. Both are made from either glass or clear plastic, most are graduated- meaning they have markings on the side indicating the amount of liquid they contain. Both are used during chemical reactions, and both are essential to a successful lab.
We hope this brief crash course in science lingo helps you to sound smarter among your peers. Until next time, happy culturing! July 26, With mixing cylinders, the metered liquid does not pour directly, but is often removed using a cannula.
A graduated cylinder is meant to be read with the surface of the liquid at eye level, where the center of the meniscus shows the measurement line. Typical capacities of graduated cylinders are from 10 mL to mL. Beakers may be made of glass, metals such as stainless steel or aluminum, or certain plastics like polythene or polypropylene. A common use for polypropylene beakers is gamma spectral analysis of liquid and solid samples. The Standard or "low-form" beakers, which are often referred to as Griffin Beakers, typically have a height about 1.
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.
