PYREX® VERIFIED Volumetric Flasks

Are your current volumetric flasks individually guaranteed to meet class A tolerances?

Are they individually traceable to lot based Certificates of Analysis for compliance and better tracking?

Corning's new VERIFIED volumetric flasks are!

Corning has developed a process that validates the measurement of each individual flask's capacity per ASTM E-542 during production, guaranteeing conformance to Class A specifications called out in ASTM E-288.

Corning's new 5646 series VERIFIED volumetric flasks are guaranteed to meet Class A volumetric tolerances on every single flask.

Choosing the right type of volumetric flask is critical to your work! And Corning gives you more choices:

Each flask is labeled with "VERIFIED" and a lot number. With this information you can access a Certificate of Analysis with lot specific data regarding both measurements and methods. Now you have the ability to trace your glassware, obtain Certificates of Analysis, and track usage.

Serialized/Certified flasks are calibrated to Class A specifications. Each flask is individually serialized and furnished with a Certificate of Identification and Capacity, traceable to NIST standards, guaranteeing its calibration.
NEW VERIFIED Class A flasks are manufactured using a process that validates the measurement of each individual flask's capacity per ASTM E-542 during production, guaranteeing conformance to Class A specifications called out in ASTM E-288. Each flask is labeled with "VERIFIED" and has a lot number enabling you to access a Certificate of Analysis with lot specific data regarding both measurements and methods.
Class A flasks are manufactured to tolerances established by ASTM E-694 for volumetric ware, ASTM E-542 for calibration of volumetric ware and ASTM E-288 for volumetric flasks. Utilizes the same tolerances as Certified and Verified flasks, but are not individually certified or verified. Lot specific certificates of compliance are available but contain no lot specific data.
Class B flasks are generally calibrated to twice the tolerance of Class A flasks.
