Our standard

Quality & testing

How each lot is specified, tested, documented and released.

PURITY

Reverse-phase HPLC

Purity is determined by HPLC with UV detection. Our release specification is ≥99%; the measured value for each lot is reported on its certificate.

IDENTITY

Mass spectrometry

Identity is confirmed by mass spectrometry, comparing the observed mass with the theoretical value for the sequence.

TRACEABILITY

Lot-linked COAs

The lot number printed on every label links to the certificate in the COA checker.

Release process

  1. Specification – each product has a written specification (sequence, formula, molecular weight, appearance, purity).
  2. Independent testing – samples from each lot are analysed by an independent laboratory. [Name the laboratory and its accreditation (e.g. ISO/IEC 17025) once contracted.]
  3. Review – results are reviewed against specification before release; non-conforming lots are rejected.
  4. Labelling – vials are labelled with product, amount, lot number, storage conditions and the research-use statement.
  5. Publication – the certificate is published to the COA checker before the lot is offered for sale.

Storage & packaging

Products are supplied lyophilised in sealed glass vials with crimped flip-off caps. Recommended storage conditions are printed on each label and product page.

The claims on this page describe the intended quality system. Before launch, ensure every statement is supported by contracts and documentation (see README pre-launch checklist).
