Quality & Testing

Every product Pure Tide Labs supplies is a research compound intended for in-vitro laboratory work only. Because reliable research depends on reliable material, each lot is independently analysed for identity and purity, and the results are documented so you can verify exactly what you are working with.

The short version: independent third-party analysis on every lot, purity and identity results reported on a lot-specific Certificate of Analysis, and that certificate available by lot number before or after purchase. Not for human or animal consumption.

Analysis

Independent, third-party testing on every lot

We do not rely on manufacturer claims alone. Each production lot is analysed by an independent laboratory using two complementary methods.

Method 01

High-Performance Liquid Chromatography

HPLC-UV 214nm · Purity quantification

HPLC separates a sample into its individual components so the proportion of the target peptide can be measured against any impurities. The resulting figure is the purity value reported on that lot’s Certificate of Analysis.

Method 02

Mass Spectrometry

ESI-MS · Identity confirmation

Mass spectrometry confirms that the compound in the vial is the peptide named on the label, by matching its measured mass to the expected value for that sequence.

Together these confirm both what the compound is and how pure it is. Both results are recorded on the certificate issued for that lot, and material is released against the specification stated on that certificate.

Documentation

Certificate of Analysis

A Certificate of Analysis is the document that records a lot’s test results. Each Pure Tide Labs certificate is lot-specific and shows the product identity, the measured purity, the analytical methods used, the appearance, the lot number and the date of analysis.

Rigour

Reference standards and analytical rigour

Meaningful test results depend on validated methods and recognised reference standards. Our testing partners work to established analytical practices, with traceability from lot to lot.

Pharmacopoeia-benchmarked identity

Identity confirmation is benchmarked against recognised reference standards such as those published by the European Pharmacopoeia and the United States Pharmacopeia.

Recognised reference standards

GLP-aligned processes

Laboratory processes follow the principles of Good Laboratory Practice for consistency and repeatability across every batch.

Good Laboratory Practice

Lot-to-lot traceability

Validated methods and documented records mean each vial can be traced back to the analysis that released it.

Documented & auditable

Handling

Manufacturing, lyophilisation and handling

Peptides are supplied as a lyophilised (freeze-dried) white powder. Lyophilisation removes water under vacuum, which keeps the peptide stable for storage and transport far better than a liquid would.

Storage on arrival

Store lyophilised material sealed and protected from light, within the temperature range stated on that lot’s Certificate of Analysis.

Handling and reconstitution volumes are noted on individual product pages so your working concentrations stay accurate across a study.

Compliance

Research Use Only

All Pure Tide Labs products are sold strictly for in-vitro laboratory research. They are not medicines, food supplements, cosmetics, medical devices or foods, they are not intended for human or animal consumption, and they have not been assessed or authorised by the MHRA for safety or efficacy. By ordering, buyers confirm they are qualified researchers purchasing for legitimate scientific use, and that they are 18 or over. If you have a compliance or documentation question, please contact sales@puretidelabs.co.uk before ordering.
