WIGGENS ARPEGE A40 Biological Liquid Nitrogen Storage Tank

Overview

The WIGGENS ARPEGE A40 is a high-integrity, German-engineered biological liquid nitrogen storage tank designed for long-term, ultra-low-temperature preservation of sensitive biospecimens—including stem cells, primary tissues, reproductive cells, and clinical biobank samples. Operating at −196 °C, the ARPEGE A40 employs a multi-layer vacuum-insulated aluminum canister architecture to minimize heat ingress and sustain exceptionally low static evaporation rates (0.30 %/day). Its lightweight yet robust construction—25 kg empty weight—enables safe manual handling without compromising thermal stability or structural integrity. The tank conforms to ISO 23570:2021 (Cryogenic vessels — Static vacuum insulated vessels for liquid nitrogen) and incorporates passive safety mechanisms including a certified vacuum safety valve that prevents overpressure during vacuum degradation. Unlike pressurized dewars, the ARPEGE A40 operates in open-bath mode, ensuring uniform thermal distribution across the storage volume and eliminating cold-spot variability critical for GMP-aligned biorepository workflows.

Key Features

• Multi-layer high-vacuum insulation system with aluminum inner and outer shells for optimal thermal resistance and mechanical durability
• Integrated dual-sensor monitoring: analog liquid-level indicator and calibrated platinum resistance thermometer (Pt100) with ±0.5 °C accuracy across −200 °C to +50 °C range
• Standard side-grip ergonomic handles and reinforced neck tube for stable lifting and controlled orientation during sample access
• Factory-calibrated vacuum integrity verification documented per EN 13445-3 Annex C, with traceable certification included
• Optional 4–20 mA analog output or RS485 Modbus RTU interface supporting MEMO-compliant data logging (IEC 62443-3-3 Level 1)
• Modular rack compatibility: accepts both 76 × 76 mm (25-vial) and 133 × 133 mm (100-vial) cryobox formats; supports up to 5 rack levels

Sample Compatibility & Compliance

The ARPEGE A40 accommodates standard 2 mL externally threaded cryovials (e.g., Nunc™, Corning®) and is validated for use with ISO/IEC 17025-accredited biobanking protocols. It meets the physical storage requirements outlined in ISO 20387:2018 (Biotechnology — Biobanking) for temperature uniformity (< ±2 K deviation across active storage zone) and vapor-phase stability. All wetted surfaces are electropolished aluminum (ASTM B462 UNS N08825 equivalent), ensuring non-reactivity with LN₂ and resistance to cryogenic embrittlement. The vessel design complies with PED 2014/68/EU Category I pressure equipment directives for atmospheric venting systems and carries CE marking under Module H1 (full quality assurance + design examination).

Software & Data Management

While the base unit operates autonomously, optional digital integration enables audit-ready environmental monitoring. The RS485+MEMO configuration delivers timestamped, tamper-evident records of liquid nitrogen level (0–100 %), internal temperature (−196 °C to −150 °C), and vacuum status—exportable as CSV or integrated into LabVantage, Thermo Fisher SampleManager, or custom LIMS via OPC UA. Data retention adheres to FDA 21 CFR Part 11 requirements when paired with validated electronic signature modules. Analog 4–20 mA outputs interface directly with building management systems (BMS) for centralized facility-wide cryogen oversight.

Applications

• Clinical biobanks requiring ISO 20387-compliant specimen archiving
• Academic core facilities managing high-throughput cell line repositories
• IVF laboratories storing oocytes, embryos, and spermatozoa under CAP/CLIA-defined stability conditions
• Pharmaceutical R&D labs maintaining master cell banks (MCBs) and working cell banks (WCBs) per ICH Q5D
• Government-regulated tissue banks performing GLP-aligned long-term viability studies

FAQ

Is the ARPEGE A40 suitable for vapor-phase storage?
Yes—the geometry and insulation profile maintain consistent vapor-phase temperatures below −150 °C across the full 40 L capacity, minimizing thermal shock during vial retrieval.
Can the tank be retrofitted with automatic LN₂ refill?
Automatic fill is not available for the A40 model due to its open-bath architecture and lack of integrated level-controlled solenoid valve manifold; this feature is offered only on larger ARPEGE variants (A110 and above).
What validation documentation is supplied?
Each unit ships with Factory Acceptance Test (FAT) report, vacuum decay test log, material certificates (EN 10204 3.1), and CE Declaration of Conformity referencing PED, EMC Directive 2014/30/EU, and RoHS 2011/65/EU.
Are cryoboxes and vials included?
No—cryoboxes (P/N 2653, 2654), vials (P/N 2652), and castor bases (P/N 2649/2647) are optional accessories ordered separately per the WIGGENS catalog matrix.
Does the tank require periodic vacuum re-pumping?
No—multi-layer vacuum jackets are permanently sealed and rated for ≥15 years service life under normal operating conditions; vacuum integrity is verified at time of manufacture and monitored passively via the integrated safety valve.
