Volumetric Flask Manufacturer
A volumetric flask is a piece of laboratory equipment commonly used in scientific experiments, especially in chemistry, biology, and analytical studies to measure and hold a precise volume of liquid. They are also often referred to as standard flask or measuring flasks.
It is a pear-shaped piece of instrument with a long, narrow neck and flat-bottomed. On the neck, there is a line etched, known as the calibration mark. his mark indicates the exact volume the flask can hold when filled to that level, making it an essential tool for preparing solutions with precise concentrations. When a liquid is filled up to this mark, it indicates that the flask contains an exact volume, such as 100 milliliters (mL), 250 mL, or 1 liter (L).
Omsons Glassware Manufacturing Standards
Omsons Glassware Pvt Ltd is a trusted manufacturer of high-quality laboratory glassware, following strict standards like DIN, ISO, USP, ASTM, and IS. We uses DIN ISO 3585 certified borosilicate glass, ensuring its products are strong, heat-resistant, and chemical-resistant. By meeting USP standards, Omsons glassware guarantees that its glassware is safe and precise for pharmaceutical and scientific use.
Volumetric Flask’s Classes
Volumetric flasks are manufactured in two classes – Class A and Class B.
Class A – Class A calibration for a volumetric flask means that the flask has been manufactured to a high level of accuracy in measuring liquids. These flasks meet strict standards like ISO or ASTM, ensuring precise volume measurements. Class A volumetric flasks are used in laboratories where accuracy is crucial, such as in pharmaceutical and chemical testing. They are calibrated at a specific temperature, usually 20°C & 27°C, to ensure consistency. Because of their precision, they are preferred over Class B flasks, which have a slightly higher margin of error. Proper handling and regular calibration checks help maintain their accuracy.
Class B – Class B calibration for a volumetric flask means it is less precise than a Class A flask but still suitable for many laboratory uses. These flasks are made with slightly lower accuracy standards and have a higher tolerance for measurement errors. They are often used in experiments where extreme precision is not required, such as general mixing or approximate volume measurements. Like Class A flasks, they are also calibrated at a specific temperature, usually 20°C & 27°C. While they are more affordable and durable, they should not be used for critical measurements in pharmaceutical or analytical testing.
Volumetric Flasks Material
Volumetric flasks are made from 3.3 Low Expansion Borosilicate glass or high-quality plastic. Glass is preferred in most cases because it is resistant to chemical reactions and can handle heat. However, plastic volumetric flasks are useful for less sensitive applications or when there is a risk of breakage.
Volumetric Flasks Sizes
Volumetric flasks come in various sizes, ranging from 1 mL to several liters. Omsons manufactures all sizes of volumetric flasks, including 1 ml, 2 ml, 5 ml, 10 ml, 20 ml, 25 ml, 40 ml, 50 ml, 100 ml, 150 ml, 250 ml, 500 ml, 1000 ml, 2000 ml, and 5000 ml. The size you need depends on the volume of liquid you plan to measure. Smaller flasks are ideal for precise, small-scale experiments, while larger volumetric flasks are better for bulk measurements.
