A COA is a batch-specific document summarizing analytical testing performed on a particular lot of research material. For peptides, published records may include identity confirmation, purity assessment by HPLC, and appearance or format notes.

COA verified in the VaultLabs context means the batch record is published and searchable through our verification portal — linked to the lot identifier on your vial label. Verification is batch-specific, not a blanket certification of all future inventory.

Documentation supports traceability. It does not replace your laboratory's incoming material testing, method validation, or acceptance criteria.

Enter your lot or batch number in the VaultLabs batch verification tool or COA search center. Published records display analytical data, batch identifiers, and related product information when available.

QR-linked verification may appear on select batches, providing a direct path from physical label to online record. If no record appears, the batch may not yet be uploaded — contact support with your order details.

Cross-check that the product name and strength on the COA match your order SKU and vial label before use in qualified workflows.

High-performance liquid chromatography (HPLC) is a common analytical method for peptide purity assessment in research settings. Published COA records may report purity percentages and chromatographic profiles where testing was performed for that batch.

Interpret HPLC results within your laboratory's validated methods and acceptance thresholds. VaultLabs reports third-party or internal analytical data as documented — without guaranteeing identical results in your local assays.

Additional quality notes on product pages describe general handling expectations; batch COA remains the authoritative record for that specific lot.

Not every batch has online documentation at the time of order. COA publication depends on analytical release workflows and upload schedules for individual lots.

VaultLabs does not imply that undocumented batches are inferior — it means the online record is pending or available on request. Submit a documentation request for specific lot support.

Institutional buyers should incorporate COA availability into procurement timelines, especially for qualification-heavy workflows requiring pre-order documentation review.

Qualified laboratories typically file COA records alongside receiving logs, chain-of-custody notes, and internal retest data where applicable. VaultLabs documentation serves as the supplier-provided analytical reference layer.

Store digital copies in your quality management system and retain physical vial labels that match COA batch identifiers for audit readiness.

Combine COA review with storage condition verification upon receipt — especially for lyophilized peptides subject to Gulf transit temperatures.

VaultLabs maintains multiple verification entry points: batch verify tool, COA search center, product-specific COA pages, and documentation request workflows for pending lots.
