The SteadyPac Solo brings vacuum-insulated panel technology and patented PCM thermal control into a single-use corrugated format, built for global one-way lanes where validated performance is required and reverse logistics isn’t practical.

SteadyPac Solo single-use VIP corrugated shipper

The product story

SteadyPac performance.Built for one-way lanes.

Every temperature-sensitive shipment must arrive safely and within specifications, but not all lanes allow for packaging returns. Clinical sites typically don’t send shippers back, and international lanes involve customs and logistics that complicate returns. Dry ice shipments are a natural fit for the same reason, they’re single-use by nature, so there’s no return box to manage.

The Solo is designed for these challenges, featuring vacuum-insulated panels and patented double-beveled locking PCM plates, providing over 120 hours of validated thermal performance across various temperature ranges so the shipment arrives safely no matter the lane. It comes in a single-use white corrugated format, eliminating the need for reverse logistics.

When the shipment is complete, the corrugated outer goes curb-side. No return freight, no reprocessing, no inbound asset tracking.

Purpose-built foropen-loop operations.

If the lane goes one way, the SteadyPac Solo belongs in it.

Sites receive shipments. That's all they have to manage.

The Solo gives clinical supply teams the validated duration, universal SOPs and compliance documentation needed for multi-site global trials, without the reverse-logistics complexity of a reusable shipper.

One PCM family, one product line. The same plates used in the SteadyPac and SteadyPac+ work in the Solo.

Ready for every site. One set of SOPs and documentation across your entire network.

No return leg. Sites keep nothing and ship nothing back.

Where the packaging experience ends at the front door.

For one-way deliveries of high-value, patient-specific medications, with no disposal burden on the patient and no request to return a shipper.

Patient-friendly. Curbside recyclable, nothing to send back.

Clean experience. The delivery ends at the door, as intended.

Validated all the same. Full thermal performance for direct-to-patient lanes.

Dry-ice shippers are single-use by nature.

The Solo's dry-ice compatibility at −80°C, combined with single-use corrugated construction, makes it the logical fit for frozen biologics, tissue samples and any shipment that requires dry ice.

Built for −80°C. Validated dry-ice configuration, documented on request.

No returnable overhead. Validated performance without a container-return program.

Frozen-ready. Tissue samples, frozen biologics and deep-freeze product.

How it's built

VIP technology. Single-use format.

The Solo delivers the thermal core of the SteadyPac family in a corrugated outer that ships once and recycles at destination. No plastic tub. No EPP outer shell. Just the insulation system that counts.

Exploded view of the SteadyPac Solo, corrugated outer, VIP panels, and PCM plates

Insulation core

Vacuum-Insulated Panels

The same high-performance insulation core used across the SteadyPac family. VIPs deliver exceptional thermal resistance in a compact, lightweight footprint, holding validated performance over 120+ hours.

Thermal control

Patented double-beveled PCM plates

The same PCM plates used in the Cube and Cube+. The double-bevel locking design seats plates correctly on every pack-out, regardless of operator or location. Same conditioning protocol year-round.

Single-use outer

White corrugated outer shell

Single-use corrugated construction, no plastic tub, no EPP outer shell. Lighter, lower DIM weight, and curbside recyclable at the destination. Ships flat and assembles quickly in the fulfilment centre.

Key benefits

Five reasons it works for open-loop operations.

No return logistics

The Solo eliminates the closed-loop requirement entirely. Ship it out; the corrugated outer recycles at the destination. No return freight, no asset reprocessing, no tracking inbound containers. For international and one-way lanes, that's a significant operational simplification.

Universal year-round design

The same PCM conditioning procedure runs in January and July. One SOP, no seasonal changeover. For teams managing clinical sites across multiple time zones and climates, a single conditioning protocol cuts training overhead and eliminates seasonal changeover risk.

120+ hours validated

Premium thermal duration, confirmed in ISTA-certified lab testing. Whether the transit window is 48 hours or six days, the payload stays in range, the same validated duration the Cube is known for, in a single-use format.

Part of the SteadyPac ecosystem

The Solo uses the same patented PCM plates as the Cube and Cube+. Operations running both closed- and open-loop lanes work with one PCM system, one conditioning procedure, one SOP family, and when a lane switches from reusable to single-use, the plates are interchangeable.

Lower dimensional shipping cost

Lower tare weight and a compact footprint reduce DIM-weight charges on outbound shipments, and on high-frequency lanes the difference compounds quickly. The SteadyPac Solo also ships flat to the fulfilment centre, cutting inbound freight and warehouse cube.

Job

The Solo is available in the same four payload volumes as the SteadyPac Cube. 3L, 10L, 16L and 28L. All four share the same validated 120+ hour duration and the same universal year-round SOP.

Operator

The Solo covers three PCM temperature ranges and works with dry ice, giving operators one system built for whatever the shipment demands. Add a shipping label and send it, no returns to track.

One thermal platform

Single-use outer.Same thermal core.

A single-use shipper shouldn’t mean single-use thermal cost. The Solo’s corrugated outer recycles at destination, but the VIP panels and PCM plates it’s conditioned with are the same reusable, non-expiring components as the rest of the SteadyPac family.

One conditioning system.

The same PCM plates as your depot reusables work in the Solo.

Multi-site ready.

Universal SOPs and documentation across every investigator site.

No return leg.

Sites keep nothing and ship nothing back.

Documentation

Validatedbefore it ships.

Every SteadyPac Solo configuration comes with ISTA-certified testing data and a pre-qualified documentation package. Your team doesn’t run the validation — TempAid already has.

Qualification summary

Temperature chamber test results, peak external temperatures, and confirmation of performance

ISTA test report

7D/7E temperature profile data and internal temperature results delivered in a fully audit-ready report

ISTA 3A drop test

Validated to withstand real-world shipping hazards, drop, compression, and vibration testing that confirms your mailer and its contents arrive intact.

Pack-out SOP card

A single card with one-page, step-by-step instructions; insert, seal, ship. Everything your team needs to pack out correctly, every time.

Return / reuse instruction

PCM mat retrieval, recycling stream per region

What the clients are saying

“Moving our one-way clinical lanes to the Solo removed the reverse-logistics headache entirely, validated performance out, the corrugated recycles at the site, and nothing to track back.”
