Corning Incorporated’s (NYSE: GLW) PYREX® Volumetric Glassware is now tested and calibrated in an ISO/IEC 17025 certified laboratory. As the most stringent quality assurance process for glassware, ISO/IEC 17025 certification provides ultimate precision for premium research laboratories. Additionally, it could mean up to 100 percent cost savings for laboratories requiring certification—such as those in the pharmaceutical development, forensics, and food services industries—that have previously paid for third-party certification. Although Corning’s glassware is already in compliance with ASTM standards, this new certification offers additional accuracy and precision for optimal experimental results, including chemical analysis. Corning offers both lot certification and serialized certification, providing a choice that allows laboratories to meet both their quality and cost requirements. “The ISO certification eliminates the worry of accuracy, allowing our customers to provide a product that is completely certified,” said Jeff Sauer, business director, Corning Life Sciences. “This is just one step we’re taking to provide the most dependable products for analytical and life science laboratories worldwide.” Specific glassware tested and calibrated in accordance with ISO/IEC 17025 accreditation include:

• Burets
• Volumetric flasks
• Volumetric and serological pipets
• Graduated cylinders

Corning is one of only a small number of equipment providers offering ISO/IEC 17025 certified glassware. To receive this accreditation, a laboratory must demonstrate high levels of competency for testing and calibration. ISO/IEC 17025 accreditation provides assurance that laboratories have the appropriate quality management systems and technical competence to accurately and precisely test and calibrate glassware. Corning Life Sciences brings new and innovative laboratory technologies to researchers worldwide and helps customers succeed by providing innovative, high-quality products and services in the areas of polymer science, biochemistry and molecular biology, glass melting and forming, surface modification, and characterization science.
