Volumetric Flasks
The gold standard in analytical precision. Engineered for exact volume measurement and standard solution preparation.
Precision Calibration for Analytical Excellence
In the rigorous environment of a chemical laboratory, the Volumetric Flask (Measuring Flask) is indispensable for achieving precise molar concentrations. Unlike general-purpose glassware, each flask is calibrated "To Contain" (TC, In) a specific volume with an extremely narrow margin of error at 20°C.
At Yash Instrument Company, our flasks feature a signature pear-shaped body and a meticulously calibrated narrow neck. This geometry ensures that the liquid meniscus is easily visible and adjustable, providing the sensitivity required for high-stakes analytical procedures.
Class A (Analytical Grade)
Designed for high-precision research and pharmaceutical labs. Compliant with ISO 1042, these flasks offer the highest level of accuracy and chemical durability.
Class B (Educational Grade)
Perfect for routine laboratory work and teaching environments. Provides reliable results with approximately double the tolerance of Class A.
Amber Glass Option
Essential for light-sensitive reagents. The permanent amber stain filters out harmful UV rays to prevent photodegradation of chemicals.
