Drone Ready Medical Carrier Earns Air Transport Certification for NHS Pathology Specimens

Collaboration between Solent Transport, Versapak International Ltd. and the University of Southampton advances drone logistics for UK healthcare

A new chapter for medical logistics

In a significant step forward for UK medical delivery systems, Solent Transport, in partnership with Versapak International Ltd. and the University of Southampton, has unveiled an insulated carrier designed for drone-based transport of pathology specimens. The carrier has achieved regulatory compliance for air transport of patient samples, opening the door for routine delivery via drone within the National Health Service (NHS).

The project is part of Solent Transport’s Drones for Medical Logistics (DfML) initiative, funded under the Solent Future Transport Zone (FTZ). The carrier passed rigorous tests this year to meet the International Civil Aviation Organization’s Packing Instruction 650 (PI650) requirements, which apply to biological substances classified as UN3373. This compliance is essential to safely move pathology specimens by air.

Why this matters

For many remote or island communities, getting pathology specimens rapidly to labs can be a critical logistical challenge. By enabling drone transport of such materials, the project seeks to reduce transit times, improve sample integrity, and support faster diagnosis and treatment. The DfML project is part of a broader effort by Solent Transport to integrate drones into medical supply chains across the Solent region.

The achievement demonstrates how public, private, and academic organisations can work together to navigate regulatory, technical, and logistical hurdles in the drone sector.

Engineering the carrier

The carrier was developed by Versapak International Ltd. in collaboration with researchers at the University of Southampton. The design adapts Versapak’s proven model for drone use. It underwent two key tests in accredited UK laboratories:

• A stacking test, where a stack equivalent to a three metre column of carriers was placed on top of the test unit for 24 hours with no leakage or instability.
• A drop test, where the carrier was dropped from 1.2 metres in different orientations and again showed no leakage.

These tests align with PI650 requirements for biological cargo. The certification confirms that the unit is suitable for transport of substances classified as UN3373 under the UN dangerous goods framework.

Words from the field

Tim Forrester, FTZ Programme Manager for Solent Transport, said: “As the primary supplier to the NHS, Versapak International was the natural partner to help redesign and certify a carrier fit for drone delivery.”

“This milestone demonstrates how public, private, and academic collaboration is driving innovation in healthcare logistics. By enabling compliance for air transport, we are significantly closer to a future where urgent pathology specimens can be delivered by drone, cutting delivery times.”

These remarks underscore the intent behind the initiative: not just regulatory adherence but tangible improvement in healthcare logistics.

What comes next

With the carrier now certified, Solent Transport and its partners will move toward integration into live drone trials across the region. These trials will build on prior work under the FTZ programme and the DfML project, which has already explored drone deliveries of medication and samples between mainland UK and the Isle of Wight.

The trials will help assess end-to-end operations including loading, flight, landing, hand-off, and sample integrity. They will also inform the feasibility of scaling drone logistics in NHS supply chains, particularly outside traditional transport networks.

A step toward the future of healthcare logistics

This development marks a meaningful shift from concept and regulation to actionable logistics for drone-enabled medical delivery. The certified carrier is a tangible asset in that shift, enabling a new mode of transport that aligns with healthcare’s demands for speed, safety, and reliability. As drone technology and regulatory frameworks continue to advance, this project positions the Solent region—and the NHS more broadly—at the forefront of innovation in medical logistics.
