What the cold chain is
The cold chain refers to keeping a temperature-sensitive material within an appropriate temperature range across each step it passes through — from dispatch, through transit, to arrival and storage. The aim is continuity: avoiding unnecessary warming or repeated temperature swings.
Why continuity matters
Some materials tolerate brief temperature excursions better than others. Reducing avoidable warming and getting a material into appropriate storage promptly on arrival supports its integrity. Product-specific guidance sets the expectations for a given item.
On arrival
When a shipment arrives, moving temperature-sensitive items into the recommended storage without unnecessary delay is good practice, and recording receipt supports traceability.
Frequently asked questions
Does every research peptide need cold-chain handling?
Not always. It depends on the material and format; follow the product-specific guidance.
What should I do when a cold-chain shipment arrives?
Move it into appropriate storage promptly and record its receipt.
