Frequently Asked Questions (FAQs)

What industries use ISO/IEC 17025 volumetric glassware?

• Pharmaceutical
• Industrial
• Government and public service
• Third-party testing labs
• Academic institutions
• Medical technology
• Agriculture
• Health and beauty industries

What is the difference between Serialized/Certified and Standard Class A volumetric products?

• Serialized/Certified Products: Individually calibrated with unique serial numbers, NIST traceable, and include a certificate of calibration for high-accuracy applications
• Standard Class A Products: Calibrated for general use without individual serial numbers. These are more economical and suitable for most laboratories

What does ISO/IEC 17025 certification provide?

ISO/IEC 17025 certification ensures the accuracy and reliability of calibrated glassware by verifying that it meets international standards for testing and calibration. It also demonstrates the quality and competence of Corning’s manufacturing and quality assurance processes, providing confidence in the precision of laboratory measurements.

Why is calibration important for volumetric glassware?

Calibration ensures the accuracy of measurements, which is critical for precision experiments and compliance with regulatory standards.

Why choose calibrated volumetric glassware?

It is a cost-effective option that still meets acceptable accuracy standards for most laboratory applications.

What are the features of calibrated volumetric glassware?

• Representative sample of the production lot is calibrated
• Provides acceptable accuracy for most labs
• A more economical choice if Serialized/Certified glassware is not required

Why choose Serialized/Certified Class A glassware?

Serialized/Certified Class A glassware offers verified accuracy and traceability, enhancing confidence in measurement results. It reflects Corning’s commitment to high manufacturing and quality assurance standards, making it ideal for laboratories that require a high level of assurance in volumetric precision.

What are the features of Serialized/Certified Class A glassware?

• Every piece is calibrated
• NIST traceable (National Institute of Standards and Technology)
• Certificate of calibration provided with the item’s serial number
• Certificates include EMA and ILAC-MRA logos for international recognition
• Ensures a high standard of accuracy, required by some labs

What is ISO/IEC 17025 volumetric glassware?

ISO/IEC 17025 volumetric glassware refers to laboratory glassware that has been calibrated in accordance with the ISO/IEC 17025 standard, which ensures the competence of testing and calibration laboratories. Corning calibrates this glassware in its ISO/IEC 17025-accredited lab to guarantee precision and reliability. This level of calibration meets the stringent requirements of laboratories that demand high accuracy in volumetric measurements.
