What should a laboratory check when a research product arrives?

A receiving inspection should answer three questions before the material enters normal laboratory stock: (1) did the correct item arrive, (2) did it arrive in a condition consistent with the product and shipping information, and (3) is the batch-specific documentation sufficient for the laboratory’s acceptance decision?

The inspection is primarily a traceability and condition check. It is not the same as supplier-side analytical release testing, and it does not require every laboratory to repeat HPLC, mass spectrometry or other batch-release analyses on receipt. Instead, the laboratory should verify the shipment, label, batch, physical condition and documents, then decide whether to accept the material, place it on hold/quarantine under its own procedure, or contact the supplier.

Why receiving inspection matters

A product name alone is not enough to reconstruct what entered the laboratory. Good scientific records connect the received unit to its order, supplier, batch or lot, documentation, received condition and later experimental use.

OECD guidance for GLP test items covers transport, receipt, identification, labelling, handling, storage and characterisation as linked controls.^[1] OECD Good In Vitro Method Practices (GIVIMP) similarly recommends recording supplier and batch/lot information for reagents, following manufacturer storage information, and documenting shipment condition where it is relevant to stability.^[2] These documents govern specific GLP/regulatory contexts; they are used here for general laboratory traceability principles rather than presented as mandatory rules for every Core Research customer.

Step 1 – Match the delivery to the order

Start with the commercial record. Confirm that the supplier, order reference, product name, labelled amount or format, and quantity received are consistent with the order confirmation. If the wrong product, wrong quantity or an unexpected format has arrived, record the discrepancy before the material is incorporated into stock.

Step 2 – Inspect and document the packaging

Before discarding the shipping materials, record the condition in which the consignment arrived. Photograph visible damage, crushing, leakage, wet packaging, broken seals or other abnormalities. Do not infer the chemical condition of the material from appearance alone; the purpose of the photograph is to preserve receiving evidence.

European GDP guidance for medicinal products describes the receiving function as checking that the arriving consignment is correct and has not been visibly damaged in transport, and prioritising products that require special storage.^[3] Core Research RUO materials are not being represented as medicinal products; the citation is used only because the receiving-control principle is relevant.

Step 3 – Verify the product label, batch and container

The batch or lot number is the key link between the physical material and its batch-specific documentation. Record it directly from the received unit. Also check that the container, seal and product format are consistent with what was ordered.

Step 4 – Check appearance and received temperature state

Appearance is a receiving observation, not an analytical identity test. Record gross features that are inconsistent with the product record: a broken vial, leakage, an obviously disturbed closure, unexpected colour or other visible change that the laboratory considers material.

Temperature should also be treated as an observed condition rather than an automatic verdict. GIVIMP notes that shipment stability matters as well as storage and gives the example that a reagent specified to be shipped frozen should arrive frozen, with the condition documented; a data logger provides stronger evidence where one is used.^[2]

If a product arrives warm, delayed or in a temperature state that conflicts with the product-specific shipping/storage information, do not apply a generic peptide-wide time/temperature threshold. Document the event and use the dedicated temperature-excursion workflow.

Step 5 – Match the batch documentation

Where a batch-specific Certificate of Analysis or supporting record is part of the laboratory’s acceptance process, confirm that the product and batch on the document match the material received. A CoA for the same product name but a different batch should not be used as the analytical record for the received batch.

At receipt, the question is usually whether the required documentation is present and correctly matched – not whether the receiving laboratory should independently repeat every test. The depth of document review should follow the laboratory’s own experimental and quality requirements.

From Our Work: what to capture if a receiving issue is escalated

When a shipment-related receiving concern is escalated to Core Research, the requested evidence is: order number, batch number, photographs, delivery timestamp and packaging condition. Separately, Core Research’s own batch-review workflow checks HPLC purity, MS identity, product/batch match, appearance, labelled amount/content, water or moisture, counter-ion information, CoA/document completeness and storage/handling status. If a meaningful mismatch is identified, the batch is held while clarification and/or a retest is requested. Testing is produced by the manufacturer and/or third-party laboratories; no laboratory accreditation claim is made because none has been verified for publication.

For the receiving laboratory, the practical takeaway is to capture facts that can be matched to the supplier’s batch records. The section above does not imply that customers must reproduce Core Research’s supplier-side release review or conduct the same test panel on receipt.

Step 6 – Decide: accept, hold/quarantine, or contact the supplier

The receiving outcome should be explicit and recorded. The term ‘quarantine’ is used here in its laboratory stock-control sense: material is kept out of routine use while a discrepancy is unresolved, according to the laboratory’s own procedure.

Do not send material back simply because it is on hold. A return or replacement is a separate commercial/policy process and should follow the supplier’s instructions for the case.

Step 7 – Preserve the receiving record

A receiving record is most useful when it remains linked to the later experiment. OECD data-integrity guidance treats records as part of a life cycle and emphasises controls that preserve data that affect interpretation.^[4] For a laboratory, the practical objective is that a later reviewer can reconstruct which batch arrived, its received condition, what evidence was checked and what decision was made.

• Order number / purchase reference.
• Supplier and product / exact entity.
• Batch or lot number.
• Date and delivery timestamp where relevant.
• Photographs or notes on packaging/container condition where a concern exists.
• Observed temperature state or logger record, if applicable.
• CoA or supporting batch-document reference used for acceptance.
• Acceptance / hold / escalation decision and date.
• Any supplier correspondence connected to a discrepancy.

Receiving-inspection mistakes to avoid

• Discarding the packaging before documenting a visible shipping problem.
• Recording the product name but not the batch or lot number.
• Using a CoA for a different batch because the product name is the same.
• Treating ‘warm to the touch’ as proof of degradation without product-specific evidence.
• Using appearance as a substitute for analytical identity or purity.
• Assuming that the receiving laboratory must repeat every supplier analytical test before acceptance.
• Moving a questionable unit into normal stock without recording the unresolved discrepancy.
• Returning material without first following the supplier’s case-specific instructions.

Frequently asked questions

Does every research product need to be quarantined when it arrives?

No. Hold or quarantine is appropriate when a discrepancy is unresolved or when the laboratory’s own procedure requires it. Material that meets the laboratory’s receiving criteria can be accepted directly.

Should I weigh the vial or repeat HPLC/MS during receiving inspection?

Not as a universal rule. Receiving inspection is primarily a condition, identity/label, batch and document check. Independent analytical testing should be driven by the laboratory’s study or quality requirements, not added automatically to every delivery.

What if the CoA batch number does not match the vial?

Do not use that CoA as evidence for the received batch. Hold the document-based acceptance decision and request the correct batch-specific record or clarification.

What if the shipment feels warm?

Record the shipment condition and use product-specific evidence. Warmth alone does not establish degradation. Follow the dedicated warm/delayed shipment workflow.

What information should I send Core Research about a delivery concern?

Send the order number, batch number, photographs, delivery timestamp and packaging condition.

When can the material move into accepted laboratory stock?

When the required order, product, batch, received-condition and documentation checks are sufficiently consistent with the laboratory’s own acceptance criteria and any material discrepancy has been resolved.

Key takeaway

Receiving inspection is the hand-off between shipping and experimental traceability. Match the delivery to the order, document the packaging, record the product and batch, assess appearance and temperature state, match the required batch documents, then record an explicit accept / hold / contact decision. The objective is not to prove every quality attribute at the receiving bench; it is to ensure that the material entering laboratory stock is identifiable, documented and consistent with the evidence required for its intended research use.
