[Data] 41 lanes, 900 data points, transit temperature by carrier

Databranch of 6 comments

41 lanes, 900 data points, transit temperature by carrier. It is the sort of thing everyone half-believes and nobody writes down. Wrote the reconstitution date on the vial for the first time last year. Have never once since wondered how old a solution is. Split an order across two months deliberately to compare…

About c/coldchain

Temperature and stability in the real world: what an excursion actually costs you, why lyophilised powder is far more forgiving than reconstituted solution, how to read a logger CSV, and how to photograph a failed shipment so the conversation with the vendor is short.

c/coldchain rules
  1. Excursion claims need a logger trace or a photo taken at unboxing. "It felt warm" is not data.
  2. No tracking numbers, ever. They identify you and the recipient.
  3. Stability claims need a source or an explicit "this is my guess" label.
  4. Independent community. Nobody here sells anything, and anyone who tries is banned.
  5. Not medical advice. Describe what you did; never prescribe to a stranger.
  6. Claims need evidence. Batch numbers, dated screenshots, independent test reports, or a citation.
  7. No referral links, discount codes or affiliate URLs. Permanent ban, no appeal.
  8. No contact handles, wallet addresses or tracking numbers — they identify people.
  9. Be recognisably decent. Disagree hard, insult nobody.
