Here are potential uses for this specific type of volumetric flask:

  1. Light-Sensitive Solutions:
    • The amber glass construction provides protection against light, making the flask suitable for storing light-sensitive solutions or substances that may be sensitive to UV radiation.
  2. Precision Volume Measurements:
    • Being Class A, the flask is manufactured with high precision, allowing for accurate and reliable volume measurements. This is crucial in analytical chemistry and quantitative analysis.
  3. ASTM E-288 Compliance:
    • The flask is designed and serialized in accordance with ASTM E-288 standards, ensuring adherence to specific criteria for accuracy, calibration, and traceability set by the American Society for Testing and Materials (ASTM).
  4. Serialized Identification:
    • Each flask is serialized, providing a unique identification number. This allows for traceability and documentation of individual flasks, which is crucial in quality control and assurance processes.
  5. Certified Accuracy:
    • The individual certificate accompanying the flask indicates that it has been individually calibrated and certified for accuracy. This is particularly significant in laboratories where precise and reliable measurements are essential.
  6. Calibration and Standardization:
    • The flask is suitable for use in calibration and standardization procedures, ensuring that measurement instruments and analytical methods are accurate and consistent.
  7. Chemical Analysis:
    • Amber glass volumetric flasks with PTFE stoppers are commonly used in chemical analysis where the substance being measured is not affected by exposure to light.
  8. Solution Preparation:
    • The PTFE stopper provides a chemically inert and secure seal, making the flask suitable for the preparation of standard solutions where accuracy in concentration is crucial.
  9. Stability Studies:
    • In pharmaceutical or chemical research, where stability studies are conducted, amber glass containers with PTFE stoppers are preferred for storing solutions that may be affected by exposure to light or UV radiation.
  10. General Laboratory Use:
    • The amber glass volumetric flask is suitable for various laboratory applications where a robust container with a light-protective feature and a chemically inert stopper is required.
  11. Quality Control:
    • Industries such as pharmaceuticals or food and beverages may use amber glass volumetric flasks with PTFE stoppers in quality control processes to ensure the accuracy of manufactured products.
  12. Long-Term Storage:
    • The PTFE stopper provides a chemically inert and secure seal, making this flask suitable for the long-term storage of solutions.
