Reliable, chain-of-custody transport for pathology and diagnostic samples. DBS-checked, UN3373-trained couriers. Direct A‑to‑B, no depot, documented on collection and delivery.
A parcel network moves boxes. A pathology sample is time- and temperature-sensitive, needs correct handling, and above all needs an unbroken, documented chain of custody. That’s a different job.
Untrained drivers don’t know UN3373 P650 packaging or how to react to a spill. Your samples ride next to takeaway parcels.
No signed handover, no timestamp, no proof of who held the sample and when. If a result is questioned, you can’t evidence the journey.
Miss a lab cut-off and the sample is wasted — a repeat draw, an unhappy patient, a delayed result. Small clinics can’t absorb that.
We connect Cambridge clinics and laboratories with pre-vetted, qualified couriers — and coordinate every run so you don’t have to.
Same-day pathology and diagnostic sample runs from your practice to the receiving laboratory, on a schedule that fits your cut-offs.
Direct clinic-to-lab runs across central Cambridge — kept quick and clean, by zero-emission cargo e‑bike where we can, with no congestion or parking hassle at your door.
As volume grows we build recurring routes — predictable pickups, lower cost per run, one less thing for your team to chase.
The requirements below aren’t optional extras — they’re the baseline for carrying your work.
Six steps, each recorded. If a result is ever questioned, the full custody trail is there.
You request a pickup by WhatsApp or email; we confirm the courier and an honest collection window.
Sample sealed to UN3373 P650 in a validated cool box — the clinic prepares, the courier verifies.
Collection receipt signed and timestamped at pickup. Custody formally passes to Hartwell.
Straight A‑to‑B, no depot, no mixing with parcels — one courier, start to finish.
Delivered to the lab with signature and photo confirmation. Custody passes to the receiver.
Both clinic and lab notified. A job is only invoiced once it’s delivered.
We focus on central Cambridge and its cluster of clinics and laboratories — short, direct routes we cover quickly, kept low-emission by cargo e‑bike where we can.
Every run is quoted up front by zone and urgency — with clear surcharges for urgent jobs, extra stops or out-of-zone. No parcels-network surprises, no hidden per-item fees.
Start with a no-obligation trial run so you can judge the reliability before you commit to anything.
Cambridge · CB zones“I started Hartwell because Cambridge’s smaller clinics deserve the same careful, documented sample transport the big labs take for granted — not a parcel driver who’s never heard of UN3373. Every run carries my reputation.”
