Volumetric Flasks Grade A 250ml
Volumetric flasks, especially Class A flasks, are used for accurate and precise measurement of liquids in laboratory settings. They are crucial for preparing standard solutions, dilutions, and performing quantitative analysis where exact volume measurements are essential.
Volumetric Flasks Grade A 250ml
Key Uses:
Preparing Standard Solutions:
Volumetric flasks are essential for making solutions with highly accurate and known concentrations, which are vital for titrations and other quantitative analyses.
Dilutions:
They allow for precise dilutions of solutions to achieve desired concentrations.
Quantitative Analysis:
In analytical chemistry, where accurate volume measurements are critical, volumetric flasks are indispensable.
Solution Preparation:
They are used to dissolve solids and make solutions to the required volume, ensuring accuracy in experiments.
Temporary Storage:
While not their primary function, they can be used to temporarily store solutions during experimental procedures.
Class A Volumetric Flasks:
Class A flasks adhere to strict manufacturing standards, like ISO 1042, ensuring minimal tolerance and high accuracy in volume measurement, according to Lasec.
They are typically made of borosilicate glass, offering resistance to thermal shock and chemical reactions, says DWK Life Sciences.
They feature a precise etched ring graduation mark and are calibrated to contain a specific volume at a certain temperature, usually 20°C.
