WIGGENS VOYAGEUR Biological Cryogenic Transport Dewar

Overview

The WIGGENS VOYAGEUR Biological Cryogenic Transport Dewar is an engineered solution for the safe, compliant, and thermally stable transport of temperature-sensitive biological specimens—including infectious agents, primary cells, stem cell lines, and genetically modified organisms—under deep-cryogenic conditions. Unlike conventional liquid-phase nitrogen dewars, the VOYAGEUR series operates exclusively in the vapor-phase mode: liquid nitrogen is absorbed into proprietary porous cryosorbent material, eliminating free liquid pooling and minimizing splash risk during handling or transit. This design ensures consistent thermal gradients across the storage chamber while maintaining sample temperatures below –150 °C—well within the required range for long-term biomolecular integrity preservation. The unit’s multi-layer vacuum-insulated aluminum construction delivers exceptional thermal efficiency, enabling extended hold times with minimal nitrogen consumption, even under dynamic environmental conditions typical of air cargo holds or ground logistics networks.

Key Features

• Vapor-phase cryopreservation architecture: Eliminates direct contact between samples and bulk liquid nitrogen, reducing contamination risk and mechanical stress on vials and cryotubes.
• Integrated cryosorbent matrix: Chemically inert, high-capacity absorbent material retains liquid nitrogen uniformly and releases it slowly via controlled vaporization—ensuring stable, predictable cooling profiles.
• Multi-layer vacuum insulation (MLVI): Aluminum-walled double-jacket construction with high-vacuum interstitial space (<1×10⁻³ mbar) minimizes conductive and convective heat ingress, achieving evaporation rates as low as 0.10 L/day (V2 model).
• IATA-DGR, ADR, and RID certified: Fully compliant with international dangerous goods transport regulations for Class 2.2 non-pressurized cryogenic liquids; includes mandatory pressure-relief vacuum safety valve and UN-certified labeling interface.
• Ergonomic handling system: Reinforced polymer handles and optional wheeled base kits (not included) support manual lifting and trolley-assisted movement without compromising structural integrity or thermal seal.

Sample Compatibility & Compliance

The VOYAGEUR series accommodates standardized cryogenic storage formats including 2 mL, 5 mL, and custom-sized cryovials, microtubes, and cryobags. Each model includes vertically aligned internal canisters (e.g., V5: 372 × Ø41 mm × 280 mm; V12: 442 × Ø71 mm × 280 mm) designed for ISO/IEC 17025-aligned stacking protocols. All units undergo factory validation per EN 13407:2001 (cryogenic vessels for transport) and are supplied with EU Declaration of Conformity (DoC) and IATA Technical Instructions Annexure documentation. For GLP/GMP-regulated workflows, optional traceable temperature data loggers (Order No. 2548-DL) provide time-stamped, ±0.5 °C accurate records compliant with FDA 21 CFR Part 11 audit trail requirements.

Software & Data Management

While the VOYAGEUR dewar itself is a passive thermal system, its optional 2548-DL data logger integrates seamlessly with WIGGENS’ CloudLink™ platform (v3.2+). This Bluetooth-enabled device records ambient and internal chamber temperatures at user-defined intervals (1–60 min), stores up to 32,000 data points, and exports encrypted CSV or PDF reports compatible with LIMS and ELN systems. Calibration certificates are NIST-traceable and include uncertainty budgets per ISO/IEC 17025. No proprietary software installation is required—data sync occurs via web-based dashboard accessible from any secure enterprise network.

Applications

• Transport of Category B biological substances (UN3373) and select Category A agents (UN2814/UN2900) under IATA Special Provision A160.
• Inter-laboratory exchange of clinical biospecimens for biobanking consortia (e.g., BBMRI-ERIC, ISBER standards).
• Field deployment of cryopreserved reagents for point-of-care diagnostics and mobile sequencing platforms.
• Logistics support for Phase I–III clinical trial sample chains requiring documented cold chain continuity from collection to central lab analysis.
• Backup storage during LN₂ supply disruptions, where extended hold time (>10 days for V12/Voyageur Plus) mitigates operational downtime.

FAQ

Is the VOYAGEUR dewar suitable for air transport of infectious materials?
Yes—each unit is pre-certified for IATA-DGR Section 2.8.2.2 (UN3373) and supports Special Provision A160 when used with validated packaging configurations.
Can the dewar be used for long-term storage, or is it transport-only?
It is optimized for transport (up to 14 days depending on model and ambient conditions), not static storage; for >30-day retention, stationary liquid-phase dewars with active monitoring are recommended.
What maintenance is required between uses?
After each transport cycle, perform visual inspection of vacuum integrity (no frosting on outer wall), verify safety valve operation, and clean interior with 70% ethanol; no recalibration is needed unless physical damage is observed.
Are custom internal configurations available for non-standard vial formats?
Yes—WIGGENS offers OEM engineering services for bespoke canister layouts, including 5 mL vial support; lead time is typically 8–12 weeks from approved drawing submission.
Does the data logger meet regulatory requirements for clinical trial sample tracking?
The 2548-DL meets FDA 21 CFR Part 11, EU Annex 11, and ISO 13485:2016 Annex C requirements for electronic record integrity, including role-based access control and immutable audit logs.
