Lot identification
Products should be associated with clear lot or batch identifiers where applicable so documentation can be matched to the material supplied.
Quality standards
Documentation you can check
Our quality standards begin with traceability. A label is not enough. Researchers must be able to identify what they ordered, match it to a tested lot, and review the available supporting documentation.
Independent analytical documentation
Where independent testing is available, we make the documentation accessible. HPLC data is reported by the testing laboratory. We never reframe results to make unsupported claims.
Documentation review
We review available laboratory analysis for information such as compound name, lot or sample reference, test date, laboratory, method, and reported findings before publication to the COA database.
Handling and fulfillment
Research materials are stored, packed, and fulfilled according to the handling requirements established for the applicable product and our operational procedures.
Issue resolution
If a documentation mismatch, labeling issue, shipping problem, or other quality concern is identified, we investigate the affected order or lot and take appropriate corrective action.
Quality is not a single purity number. It is the system that connects identity, documentation, handling, traceability, and accountability.
