Introduction: The Challenge of Precision on the Move

Every mile matters when you’re transporting clinical materials. For Phase I research sites, even a single temperature deviation can disqualify data, delay patient care, or jeopardize progress. Traditionally, sites rely on a patchwork of ice packs, coolers, and manual logs – systems that were never designed for precision or transparency.

In July 2025, Matt Maxwell, a veteran clinical operations executive, set out to test a better way. The goal was simple: test the capabilities of Artyc’s Medstow 5L-I under Controlled Room Temperature (CRT) conditions – roughly 20–25 °C – and prove that it could deliver both stability and traceability at scale.

The result was a 250-mile journey from Highlands, North Carolina, to Black Creek, Georgia, completed over 5 hours and 6 minutes in the trunk of a vehicle – and it may mark a turning point for clinical supply chain logistics.

The Setup: Testing the Medstow 5LI in Real-World Conditions

The Medstow 5L-I is an actively controlled, battery-powered portable cooler built to maintain precise temperature ranges – refrigerated (2–8 °C), frozen (-18 to -25 °C), or Room Temperature (15–25 °C). Unlike passive systems that depend on preconditioned ice or unsustainable materials, the Medstow 5L-I uses dual batteries, smart sensors, and simple controls to automatically compensate for environmental fluctuations.

For this test, the cooler was set to Room Temperature and placed in the trunk of a mid-sized sedan under typical summer conditions – high humidity, variable sunlight, and stop-and-go highway traffic.

Matt Maxwell wasn’t testing in a lab. He was testing in the real world – the same unpredictable conditions that research couriers and clinical teams face every day.

The Journey: 250 Miles, 5 Hours, 6 Minutes, Zero Deviations

At 11:19 AM, the Medstow 5L-I began its journey south from Highlands, NC. By 4:26 PM, it had arrived in Black Creek, GA – covering 250 miles through five major route transitions, including Hartwell, Elberton, Wrens, Wadley, and the Jim Gillis Historic Parkway.

Here’s what the data shows:

• Temperature Stability: Internal temperature maintained between 22-23 °C the entire trip (mean kinetic temperature = 22.55 °C).

• Effortless Power Management: The Medstow 5L-I operated continuously throughout the five-hour drive, powered by its onboard battery. For extended or multi-day trips, it can be easily recharged on the go using a standard 12V vehicle outlet or inverter, eliminating the need for external battery swaps or downtime.

• Route Precision: 300+ GPS coordinates logged, detailing every segment of the route.

• Complete Traceability: Each data point (temperature, battery, lid openings, ambient readings) captured for full auditability.

The Medstow 5L-I didn’t just maintain control. It documented every moment of it.

The Data: What It Revealed About Performance

The journey’s dataset tells a story of precision and stability:

1. Consistent Control: Despite being stored in the trunk, where ambient temperatures fluctuate rapidly, the 5L-I’s internal sensors held the chamber within the target range.

2. Flexible Power Options: The system’s design allows easy plug-in charging through car outlets, standard wall sockets, or auxiliary power stations, enabling continuous operation over multi-day routes.

3. Full Audit Trail: Over 300 unique timestamps were logged into the Artyc portal, giving the team a second-by-second record of temperature, location, and environment.

This kind of dataset simply isn’t possible with passive systems, which might record start and end temperatures at best. For compliance-driven environments, where Good Distribution Practice (GDP) and Good Clinical Practice (GCP) require continuous temperature monitoring, this level of granularity transforms how audits are conducted.

The Human Element: Why It Matters for Clinical Sites

To understand why this test is significant, you have to understand the world Matt Maxwell comes from.

Matt has led operations across dozens of clinical research sites in North America. He’s managed Phase I-IV trials, overseen thousands of shipments, and experienced firsthand how fragile the cold chain can be.

In traditional workflows, Phase I sites rely on conventional freezers, portable ice packs, or dry ice. But these methods are labor-intensive and error-prone:

• Ice overshoots the target range and freezes sensitive materials.

• Dry ice requires IATA certification and can flash-freeze or evaporate mid-route.

• Passive shippers provide no visibility until it’s too late.

The Medstow 5L-I changes this equation by combining active regulation with real-time data access – effectively turning what was once a black box into a transparent system.

The Bigger Picture: Structural Resilience in Clinical Logistics

The concept of “structural resilience”, the ability of systems to absorb shocks and maintain function, is rapidly becoming a cornerstone of modern clinical operations. The Medstow 5L-I embodies that philosophy.

By eliminating dependence on external refrigeration, passive packing, or manual oversight, it provides redundancy and intelligence built into the device itself.

When paired with Artyc’s cloud-based portal, this hardware-software ecosystem ensures:

• Real-time temperature and GPS monitoring

• Automated excursion alerts

• Chain-of-custody visibility

• Battery and performance diagnostics

For global research networks, this creates a reliable foundation for risk mitigation and scalability - particularly as decentralized trials grow and materials move further from controlled environments.

Why This Matters Beyond One Journey

What makes Matt Maxwell’s 250-mile run so significant isn’t just the data. It’s what it represents. Proof that long-haul, actively controlled transport can be simple, repeatable, and affordable.

For years, the industry has accepted temperature excursions as “inevitable.” Artyc’s Medstow 5L-I challenges that narrative. It shows that precision logistics can be portable, sustainable, and audit-ready – no matter the distance.

Conclusion: Redefining the Cold Chain

As the clinical landscape evolves, so too must the systems that keep it running. The 5L-I’s performance across 250 miles and five hours of heat exposure is a preview of the future:

• One where temperature control is active, not passive.

• Where data visibility is real-time, not retrospective.

• And where trust in the supply chain is earned through transparency.

Artyc’s Medstow 5L-I transforms logistics from a potential point of failure into a point of strength.

This is what structural resilience looks like. Not in theory, but in motion.
