01 / Our quality philosophy
Quality through transparency.
We put product information and available documentation within reach so researchers can review materials in the context of their own requirements.
Quality & transparency
Transparency at
every step.
Learn about our approach to sourcing, documentation, and research material quality.
Research requires questions.
Transparency makes room for them.
02 / Sourcing approach
Ask the right questions.
Review the product listing and available certificate before ordering. For sourcing details that are not published, contact our team for the information available for that material.
03 / Documentation standards
Start with the source.
Our documentation hub links to the existing product certificates. Review each original document for its sample identification, methods, dates, and reported results.
04 / Available testing information
Review the evidence.
Testing information is provided in the published certificates where available. We do not extend the results of one document to materials or batches it does not identify.
05 / Product traceability
Make the connection.
When asking about a particular material, include its name and any lot or batch identifier on your packaging. Support can help you locate the available corresponding information.
