Storage, Cold-Chain and Delivery Controls
Knockout Labs holds stock in the UK and controls its storage. Any cold-chain or temperature-control statement must be confirmed for the specific product and order. This page does not establish a catalogue-wide cold-chain delivery service.
Three records answer three different questions
| Stage | Record to establish | What it can answer |
|---|---|---|
| Stockholding | Applicable storage instruction and available storage record | How the identified stock is meant to be held |
| Dispatch and transit | Agreed service, packaging and any monitoring record | What arrangements apply to the journey |
| Receipt | Delivery time, container condition and any logger result | What was observed when the shipment arrived |
An instruction to store a material at a particular temperature is not a record that the temperature was maintained. A carrier service description is not a measurement inside the parcel. Keep the instruction, arrangement and observation separate.
Confirm conditions before ordering
Ask customer service for the storage instruction for the exact product, form and presentation. Where your research depends on a defined transit condition, state that requirement before purchase and request written confirmation of whether it can be met.
Do not infer the use of insulated packaging, cold packs, temperature loggers or a particular carrier from a product photograph. Any such arrangement needs confirmation for the order. UK delivery covers the commercial delivery route; catalogue storage and stability covers material evidence.
Inspect the shipment against the agreed arrangement
Record the delivery time, products, quantities and container lots. Note damage, missing items or a difference from the confirmed packaging arrangement. If a logger was agreed and supplied, preserve its record with the order rather than relying on a single displayed reading.
The receiving checklist provides the record fields. For a damaged or leaking container, follow your organisation's safety procedures and report the concern without unnecessary handling.
A concern needs an evidence-based decision
Temperature at receipt cannot reconstruct the entire journey. Appearance alone cannot establish that a material retained its specification. Keep suspect stock identifiable and raise the concern through delivery support, including any available time and temperature history.
Knockout Labs does not assign a universal transit tolerance or shelf life across the catalogue. Use the temperature-excursion guide to separate what is known from what needs assessment.
