Here are potential uses for this specific type of volumetric flask:
- Precision Volume Measurements:
- Being Class A, the flask is manufactured with high precision, allowing for accurate and reliable volume measurements. This is essential in analytical chemistry and quantitative analysis.
- 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).
- 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.
- Certified Accuracy:
- The individual certificate accompanying the flask indicates that it has been individually calibrated and certified for accuracy. This is important for laboratories where precise and reliable measurements are paramount.
- 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.
- Chemical Analysis:
- Clear glass volumetric flasks with wide mouths are commonly used in chemical analysis where the substance being measured is not affected by exposure to light.
- Solution Preparation:
- The wide-mouth design allows for easier filling and dispensing of solutions, and the PTFE stopper provides a chemically inert and secure seal. This makes the flask suitable for the preparation of standard solutions where accuracy in concentration is crucial.
- General Laboratory Use:
- The wide-mouth heavy-duty design with a PTFE stopper makes the flask suitable for various laboratory applications where a robust container with a chemically inert closure is required.
- Quality Control:
- In industries such as pharmaceuticals or food and beverages, clear glass volumetric flasks with PTFE stoppers are used in quality control processes to ensure the accuracy of manufactured products.
- Long-Term Storage:
- The PTFE stopper provides a chemically inert and secure seal, making this flask suitable for the long-term storage of solutions.
- Research and Development:
- Laboratories may use these flasks in research and development projects where precise volume measurements are required, and accurate documentation is essential.
