What Is a Volumetric Flask?
A volumetric flask is a type of glassware for experiments. Like a measuring cylinder, it is used to measure and constant the volume of a liquid, and is characterized by its greater accuracy of measurement compared to a measuring cylinder.
A volumetric flask is generally made of glass, although some are made of plastic or resin. Its shape is that of a flat, spherical bottom with the body extending in an elongated cylinder. The opening can be sealed by plugging it with a stopper. The color can vary from a colorless transparent type to a brownish transparent type called a tea flask.
Uses of Volumetric Flasks
The uses of the volumetric flasks are explained here.
Volumetric flasks are used to keep a solution at a certain volume.
Generally, clear, colorless volumetric flasks are used. When light shielding is required for the material to be handled in an experiment, a clear, brown volumetric flask, called a "brown flask," is used. Such brown volumetric flasks are used, for example, for silver nitrate solutions, which react with light and become colored. There are a wide variety of shapes available for different applications, such as those with thicker cylinders for easy loading and unloading of liquids.
Principle of Volumetric Flasks
Generally, volumetric flasks are used to keep the volume of a liquid constant, such as when one wants to keep the concentration of a solution constant, and one of its characteristics is that it is more accurate in measurement than a female cylinder, which is used for the same purpose.
One of the characteristics of these cylinders is that they have a higher measurement accuracy than female cylinders, which are used for the same purpose. The reason for this is that the scale used for measurement, called the "mark line," is placed in the neck of the long, thin cylinder, making the diameter narrower and the accuracy of the scale higher, thereby reducing errors.
The word "TC" on the wall is an abbreviation for "receiving," meaning that the volume of liquid added up to the marked line is the same as the volume shown on the display. The volume tolerance, which is a measurement error, is determined for the size of the sample to be measured, and the amount of liquid added to the marked line is the same as the indicated volume.
Difference Between Volumetric Flasks and Volumetric Cylinders
Both are laboratory instruments made of glass and are similar in the sense that they both measure the volume of a liquid, but there are differences in their uses and characteristics.
Volumetric flask has a specified volume; for example, a 100 ml volumetric flasks are used to dilute a liquid component to a specified volume of 100 ml. In other words, it is "an instrument used to dilute a liquid accurately of a specific concentration to a specified volume. On the other hand, a female cylinder, as its shape indicates, has a cylindrical body with a scale on it, and the amount of a liquid component that flows into the cylinder is read from the scale. Therefore, a measuring cylinder is a "glassware for measuring the volume of a liquid," and its use is different from that of a volumetric flask.
