We distinguish reported results from tests still pending. A limited release based on HPLC purity and content is not a completed six-area test panel.
How a lot reaches the catalogue
01
Sourcing
Reference materials are procured from established peptide manufacturers and received under controlled handling.
02
Independent verification
The laboratory report identifies what was measured for the selected lot. Identity is confirmed only where the report contains an applicable identity result.
03
Report and release decision
Source reports and lot status are published separately. A published report does not by itself mean the lot is released or every planned test is complete.
04
EU dispatch
Released lots are dispatched from within the EU with documented handling terms for the material.
Results, criteria and pending tests
HPLC purity and content
For peptide release based on HPLC purity and content, VERIPHASE requires reported HPLC purity of at least 99% and accepts a content shortfall of no more than 0.50 mg per component. Amounts above the nominal amount are accepted under this content criterion. These are VERIPHASE acceptance criteria; the laboratory reports measurements. This partial-release policy applies only to explicitly selected lots; it does not automatically apply to other or future lots.
Peptide blends
Blends are assessed component by component: a combined total does not replace each component’s content result. Fragment and full-length identities are distinguished in the product record.
Laboratory solutions
For BAC lot 26-0043, VERIPHASE has authorised a limited release based on the reported benzyl alcohol assay of 0.89%. pH, sterility and endotoxin tests remain pending. This decision applies only to this lot and does not establish sterility or completion of the laboratory-solution test panel.
Additional methods
MS identity, endotoxins, elemental impurities, bioburden and sterility are reported only when results are available. A pending test is not a pass. Other measurements are published only when attributable to the lot.
Release decisions follow the documented criteria
A lot outside the applicable acceptance criteria is not released. Pending tests are shown separately and are not described as passed. Consult the COA Vault for the report and status of the lot.
Research use only. All materials are in-vitro laboratory reference standards — not for human or animal use, and no medical or therapeutic claims are made.
