The PA 55640 Volumetric Flask from Iwaki is a Class A precision volumetric flask designed for preparing solutions with highly accurate volume, such as standard solutions and quantitative dilutions. The amber layer on the flask wall protects light-sensitive solutions, while the glass stopper ensures a tight seal so that solution homogeneity is maintained during mixing.
This volumetric flask is commonly used in analytical chemistry, pharmaceutical, quality control (QC), research institution, and educational laboratories. Its applications include preparing standard solutions for titration and instrument calibration, sample dilution, and temporary storage of light-sensitive solutions such as silver nitrate and potassium permanganate.
