Class A Amber Volumetric Flasks

Amber stained volumetric flasks are manufactured per ASTM E-288 Class A Serialized glassware specifications. Calibrated to contain (TC), these flasks feature white enamel printing and diamond etched graduation line. Our flasks feature heavy-duty and uniform wall thickness and a wide mouth design for easy pipette access. Amber stain protects light sensitive materials. Our volumetric flasks feature QR code integration to facilitate quick and easy access to certificates of calibration, certificates of conformity, and user manuals where applicable. This is first of its kind innovative technology only available on United Glassware. We recommend the NeoReader app for scanning QR codes. Simply point your smartphone to the QR code printed on the flask. Enter the serial number when promoted and the app automatically takes you to the certificate screen.
