ALWSCI 20 ML Volumetric Measuring Flask Set NS12/14 Glass Stopper, Graduated, ASTM Class A Borosilicate Glass 3.3 for Laboratory, 2 PCS

Volumetric Flask : It is a cylindrical-shaped container with a narrow neck and designed to hold a specific volume of liquid and is calibrated to deliver an exact volume when filled to a certain mark Accuracy Class A : Class A flasks are used for analytical chemistry work, Its tolerance, temperature, precision, and volume will be indicated on the glassware. Volumetric flasks with a batch number and accuracy Class A are supplied with a batch certificate. This certificate documents the mean value obtained from measuring the batch in question, the standard deviation and the day of issue Solid Glass Stopper : The glass stopper is a type of cap made of glass that fits snugly onto the neck of the flask, provides a secure seal, preventing evaporation and contamination, and making it ideal for storing and transporting liquids Application : Preparation and storage of standard solutions; Measuring liquid amounts; Diluting solutions; Mixing several components; Measurement analysis; Volumetric measurement To ensure a long service life for your volumetric glassware and to exclude possible volume changes, these glass products should not be heated above + 250°C in drying cabinets or sterilisers
