Trust Trace Glassware Certificates
Download certificates for Eisco LabGlass. We provide four types: Batch, Individual and NABL calibration certificates, and Certificates of Compliance for our Class A volumetric glassware range.
You do not need to know which type you have. Enter the code printed on your glassware and we will work it out.
Where to find it on your glassware
Your glassware is printed with its class, capacity and standard. The codes you need are the boxed batch code and, on serial-numbered items, the vertical serial. The diagram below shows the older two-line marking; newer glassware carries a single eight-character batch code such as L09000EA instead.
What each certificate means
Certificate
What it tells you
Certificate of Compliance
Declares the material and specification of your whole batch. It is a declaration, not a measurement — no readings sit behind it.
Batch calibration
Your batch was measured by gravimetric calibration to ISO 4787. Gives the volume and its measurement uncertainty for the batch as a whole.
Individual calibration
The exact piece in your hand was measured on its own, identified by its serial number. Gives that piece's own volume and uncertainty, not the batch's.
ISO 17025 / NABL
The same single-piece measurement, performed and issued under our NABL accreditation to ISO/IEC 17025 — the form an auditor usually asks for.
