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

  1. Precision Volume Measurements:
    • Class A indicates high precision, allowing for accurate and reliable volume measurements. This is crucial in analytical chemistry and other applications where precise quantities of substances are required.
  2. ASTM E-288 Compliance:
    • The flask is designed 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).
  3. Serialized with Individual Certificate:
    • The individual certificate and serialization provide a unique identifier for the flask, indicating that it has been individually tested and meets specified quality standards.
  4. Solution Preparation:
    • The narrow-mouth design minimizes exposure to the external environment, making the flask suitable for the preparation of standard solutions with precise concentrations.
  5. Chemical Analysis:
    • Amber glass is often used when substances are light-sensitive. The volumetric flask can be used in chemical analysis where exposure to light needs to be minimized.
  6. Quality Control:
    • Industries such as pharmaceuticals, food, and beverages may use amber glass volumetric flasks in quality control processes to ensure the accuracy of manufactured products.
  7. Long-Term Storage:
    • The PTFE stopper provides a chemically inert and secure seal, making this flask suitable for the long-term storage of solutions.
  8. Research and Development:
    • Laboratories may use these flasks in research and development projects where precise volume measurements, chemical inertness, and resistance to reactivity are important.
  9. General Laboratory Use:
    • The flask can be employed in various laboratory applications where a narrow-mouth container with a PTFE stopper is needed for accurate measurements.
