Material:Made from ASTM E438, Type I, Class A, 3.3 borosilicate glass
A volumetric flask with a glass stopper is a type of laboratory glassware used for accurately measuring and dispensing precise volumes of liquids. The volumetric flask is a cylindrical-shaped container with a narrow neck and a graduation scale for measuring the volume of liquid
A volumetric flask made to conform to a high standard is a Class A or Class 1 flask. Its tolerance, temperature, precision, and volume will be indicated on the glassware. Class A flasks are used for analytical chemistry work
The volumetric flask with a glass stopper is typically made of high-quality, chemically-resistant glass, ensuring its durability and longevity, even when used in harsh laboratory environments. The glass stopper provides a tight seal, making it ideal for use in a wide range of applications, from chemical and biological experiments to clinical and industrial analysis
Batch number certificate:Volumetric flasks with a batch number and accuracy Class A are supplied with a batch certificate
