It was first patented in 1860 by a German chemist, Emil Erlenmeyer. It is one of the most commonly used flasks to carry out various experiments in the chemistry lab, such as titration, filtration, crystallization, etc. Erlenmeyer FlaskĮrlenmeyer Flask, also known as a conical flask, is glassware comprising of conical body, flat bottom, and a cylindrical neck. Let’s take a look at few types of flasks used in chemistry labs. They come in a variety of shapes and sizes, with each one having a specific purpose associated with it. Flasksįlask is a category of glassware used in the chemistry lab. ![]() ![]() While most are clear glass vessels, some reagent bottles are colored amber (actinic), brown, or red to protect light-sensitive chemical compounds from visible light, ultraviolet, and infrared radiation. They come in a variety of sizes, shapes, and are commonly constructed of glass or plastic. Reagent bottles, sometimes also referred to as media bottles, are specially designed containers or vessels to hold chemicals in liquid or powder form. Beakers are often used to hold, mix, and heat individual chemicals or chemical mixtures. Beakers come in several sizes with volumes ranging from 5 milliliters to 10000 milliliters. Moreover, glass beakers provide more clarity for content visibility and measurement than their plastic counterparts. While plastic beakers are only used to mix the chemicals, glass beakers have high thermal stability and can be used to heat chemicals also. Beakers are usually made of borosilicate glass or plastic. They are cylindrical, have a flat bottom, and a small spout on the top to pour chemicals. Latex or nitrile gloves work as a barrier between human skin and protect them from burns, infections, and contaminations caused by hazardous chemicals.īeakers are one of the most commonly used laboratory apparatus that one can come across in a chemistry lab.
