VIBB Medical Box: Design, Performance and Real-World Applications for Power-Free Pharma Cold-Chain

VIBB Medical Box: Design, Performance and Applications

What it is—and why it exists

Cold-chain quality often fails in the last mile: power plugs are scarce, dry ice creates handling issues, and single-use foam boxes generate waste and inconsistent results. The VIBB Medical Box (Sanyou London) is a reusable, power-free carrier engineered to keep 2–8 °C reliably for multi-day missions—without mains, diesel, or dry ice. It slots straight into GDP-aligned workflows for vaccines, biologics, diagnostics and specialty reagents.

Architecture: built for temperature stability and field handling

Outer surface: plastic protective film—smooth, wipe-clean, and resistant to common disinfectants; tough enough for repeated fleet use.
Thermal core: fumed-silica Vacuum Insulation Panels (VIPs) paired with polyurethane (PU) foam. The VIPs deliver extremely low thermal conductivity in millimetres; PU adds structural stability, edges protection and helps manage point impacts.
Protective housing: hollow-board outer box—lightweight, ribbed for rigidity, and replaceable in service.
Payload space: smooth, food/medical-grade liner with rounded corners for easy cleaning.
Fleet features: moulded carry handles, document window, tamper-evident tie points, integrated data-logger pocket, optional divider set, and dedicated sleeves for phase-change packs when missions demand extended duration or tighter control.

This hybrid build keeps conduction and convection low, minimises radiative gain, and withstands loading, stacking and routine cleaning—exactly what clinical and courier teams need day after day.

Proven performance: what “6.13 days” really means

In controlled trials at +25 °C ambient, with contents pre-chilled to 2 °C and packed out per our SOP, the VIBB Medical Box maintained an internal band of 2–8 °C for approximately 6.13 days.

How to read that result—plainly:

It demonstrates multi-day compliance in typical room-temperature conditions without powered refrigeration.
Duration in your route will depend on payload mass, starting temperature, pack-out, ambient profile and door-open discipline.
For warmer lanes, longer dwell or lighter payloads, add the matched phase-change packs to extend hold time while keeping the box compact and easy to handle.

We supply a simple pack-out SOP and validation template so your pharmacy or 3PL can verify performance on your own lanes before go-live.

Pack-out SOP: five steps your team can master quickly

Pre-condition the payload to 2–8 °C. If using PCM packs, condition them to the marked set-point.
Stage the box in a cool, shaded area; place PCMs in the dedicated sleeves if required.
Load tight—use dividers to eliminate voids and prevent pouches or vials from settling during transit.
Insert the data logger in the built-in pocket; confirm time sync.
Seal and label—apply tamper ties, route label and band label; brief the driver on minimal-open practice at hand-overs.

Result: a repeatable process that fits pharmacy benches, clinical routines and courier hand-offs without fuss.

Sizes, capacities and options

The VIBB Medical Box is offered in multiple footprints and volumes so you can right-size the payload to the mission (for example: small clinic drops, inter-hospital transfers, or regional hub shipments). Options include:

Compact units for home-health and dose-level runs.
Mid-volume for surgery and pharmacy replenishment.
Bulk for hub-to-spoke movements or temperature-sensitive outreach campaigns.
All versions share the same materials architecture and accept our logger kits, divider sets and phase-change packs. Custom sizes and branding are available for fleet standardisation.

Cleaning, re-use and asset life

Wipe-clean surfaces tolerate neutral detergents and commonly used sanitisers.
Replaceable liners, gaskets and hollow-board outers extend lifespan; spares carry their own part numbers for quick re-order.
Serialised IDs support asset tracking in your WMS or simple QR-based check-in.
Refurbishment kits allow mid-life refresh without retiring the thermal core—good for budgets and sustainability.

Where it earns its keep—application snapshots

Vaccination programmes: multi-day outreach in rural areas or dense cities where power is unreliable.
Biologics and cell-based therapies: controlled 2–8 °C rides between hospitals and specialist labs.
Diagnostics and reagents: stable transport to satellite labs without packing foam mountains.
Hospital pharmacy to ward: predictable temperature between dispensary and clinic, even with inevitable corridor dwell.
Cross-border parcels: consistent performance through varying handling conditions; logger evidence simplifies release on arrival.

Frequently asked by pharmacy and logistics teams

Do we need ice or dry ice?
No for 2–8 °C at moderate ambients; the VIP-PU thermal core does the heavy lifting. For demanding profiles, add the matched PCM packs—no loose ice, no water ingress.

How do we prove compliance?
Use our validation worksheet: two pilots on representative lanes with data-logger traces and payload thermometers. Store the logs in your GDP file.

What about air freight?
The low-mass construction and compact form factor keep volumetric weight under control. Choose sizes aligned to your carrier’s common parcel tiers.

Is there a repair path after rough handling?
Yes. Edges and outers are service-replaceable; the thermal core is protected. We offer inspection guides and part kits.

Why the VIBB Medical Box is a step forward

Power-free multi-day stability at 2–8 °C—ideal for last mile and outreach.
Compact and light, thanks to VIP-led insulation rather than bulky foam.
GDP-friendly features—logger pocket, tamper points, document window—built in, not taped on.
Reusable and refurbishable, cutting waste and total cost of ownership versus single-use shippers.
Customisable to your routes, payloads and brand.
