BioChain moves organs, mRNA vaccines and radiopharmaceuticals across the Mid-Atlantic under continuous temperature telemetry and biometric chain of custody. Every consignment closes with an audit pack a regulator can reproduce.
A biological asset has a temperature band it must never leave and a viability window that started before you took possession. ColdLink plans the route against both limits at the same time.
Hypothermic preservation. Organs in static cold storage, blood products, most biologics.
Frozen. Reagents, plasma derivatives, certain investigational products.
Ultra-cold. mRNA vaccine stock and dry-ice shipping configurations.
Dispatch is alerted as a cooler approaches its threshold, not once it has breached it. Dispatch therefore has time to reroute or fix the hardware before the temperature goes out of range.
Heart, lung. The shortest window among the organs listed.
Liver. Cold ischemia time sets the limit for the route.
Kidney. The longer window is monitored the same way.
F-18 radiotracer half-life. Radiopharmaceuticals decay in transit, so the dose that arrives is lower than the dose that left.
Four stages, each one binding a person, a time and a temperature to an immutable record, with no manual entry by the courier.
A hospital raises a transport request in the client portal. ColdLink builds the route against live I-95 conditions, weather, and the specific viability window of the asset, then commits to a delivery time rather than an estimate.
The courier authenticates biometrically at pickup. That electronic signature binds directly to the record state, giving a traceable, immutable custody transfer that satisfies FDA requirements for closed systems.
Bluetooth sensors inside the cooler stream internal temperature and location for the whole journey. Drift toward a threshold raises a dispatch alert while a reroute is still possible.
The recipient signs, and delivery generates a compliance pack containing the full temperature trail, the signature log and the system access log. It is built to be reproduced on demand for inspection, months later, without anyone reconstructing it by hand.
A dispatcher cannot hold live traffic, a weather front and a four-hour viability window in their head for every consignment at once. The engine does that arithmetic and returns a delivery time the receiving hospital can plan around.
Live traffic on the roads the consignment has to cross, including the Baltimore and Washington bottlenecks.
Current conditions and forecast for every segment, not only the two endpoints. A front sitting over Wilmington changes the plan for a Philadelphia run.
This window comes from the cargo itself. A heart allows four to six hours. An F-18 radiotracer has lost half its activity after 110 minutes. ColdLink treats that window as a fixed limit on the route.
ColdLink returns the route that clears the viability window with the most margin, and the delivery time that route produces.
Dispatch also gets the point at which the chosen route stops clearing the window. The consignment is then watched against that threshold for the rest of the run.
Traffic and weather move, so the arrival estimate moves with them. ColdLink re-runs the route for every active consignment and tells dispatch when the original plan no longer clears the window, while there is still time to change the route.
Temperature drift toward a limit raises a dispatch alert on approach. The alert leaves time to reroute or intervene on the hardware before the cooler leaves its band.
The courier's phone, the dispatch floor and the audit console all write to the same consignment record, so nothing has to be exported from one and merged into another.
Hospital basements and loading docks often have no signal, so the app is built to work without one. Biometric sign-offs and NFC seal scans complete locally and sync the moment the handset reconnects.
A live map of every active cooler, its GPS position and its internal temperature, watched around the clock by dispatchers who act on exceptions.
Export a tamper-evident trail of every system access and every data modification. Built for the closed-system requirements a federal or hospital auditor will test, and available without raising a support ticket.
Every BioChain consignment closes with the same pack in the same format, and it can be reproduced on demand.
BioChain operates from Columbia, Maryland, sitting on the I-95 stretch between Baltimore and Washington. Federal health agencies, academic medical centres and biotech laboratories cluster along that corridor, and traffic on it is one of the inputs ColdLink routes against.
Dispatch runs continuously. Couriers are trained in biological material handling and hold the credentials the receiving facility will ask for at the dock.
Dispatch is alerted while the asset is still in band, not after a breach. A dispatcher assesses the route and acts immediately where a reroute or a hardware intervention preserves the consignment. The approach, the alert and the action are all written into the audit pack, so the record shows the excursion was prevented rather than simply not reported.
Every transfer is a biometric authentication bound to the record state at the moment it happens, which is what FDA 21 CFR Part 11 asks for in a closed system. The biometric authentication is itself the signature, so there is no scanned image to store. Combined with the continuous temperature trail and the system access log, it produces a pack that can be reproduced on demand for inspection.
Yes. The courier application is offline-first by design, because hospital basements, loading docks and cold rooms routinely have no signal. Biometric sign-offs and NFC seal scans complete on the handset and cache locally, then synchronise automatically on reconnection with their original timestamps intact.
We review the assets you move, the temperature bands and viability windows they demand, your receiving facilities and your own regulatory obligations. You get back a written service level agreement with committed delivery windows, plus a sample audit pack in the exact format your inspectors would receive. There is no charge for the review.
Tell us what you move and where it has to be delivered. You will get a written SLA with committed windows and a sample audit pack in the format your inspectors would see.
