Sending peptide samples for laboratory testing

1. Describe the material and the question

Provide the full compound name, stated lot or batch, label claim and formulation. Say whether the material is a solid, solution or blend, and disclose known solvents, additives or hazards. Explain whether you want identity evidence, chromatographic purity, measured content or another agreed analysis.

Use the portfolio to describe the compound, then confirm method availability with intake. A listed name does not establish suitability for every formulation or analysis.

2. Confirm the requirements in writing

Create a draft request and review it through the client portal. Before shipping, obtain the confirmed sample amount, container or format, preparation instructions and current destination details. Ask whether the analysis consumes the sample and clarify any retention or return request.

• Confirm that intake is accepting your requested material and analyses.
• Confirm the reporting basis if you need a content result.
• Ask about the accepted route for your country and any relevant carrier or customs requirements.
• Use the agreed instructions for the specific order; do not assume delivery is available from every location.

3. Keep identifiers consistent

Label each accepted sample as instructed and include the order reference. Keep vial identifiers and lot information consistent between the request, package and your own records. For multiple samples, provide a clear mapping so each container can be associated with the intended analysis.

Retain a copy of the request and shipment records. Describe what you submitted accurately; a label claim is information supplied for testing, not a result established by the label itself.

4. Follow material-specific handling instructions

Do not use a general guide as a universal temperature or preparation protocol. Ask intake how to package and handle your accepted material, including whether any specific transport conditions are required. Avoid dissolving, transferring or changing the sample unless the laboratory requests it.

The BIPM comparison report linked below illustrates that storage, transport and handling conditions are assessed for a defined material. Its instructions are not the shipping protocol for your sample. The accepted order and intake guidance take priority.

5. Follow up through the portal

Use the client portal for order-specific questions and follow the sample’s intake status. If a package or sample detail differs from the agreed request, tell support promptly so it can assess the effect on the requested work.
