Airs ATS-1200 Intelligent Cryogenic Standard Reference Material Storage Cabinet (Master-Satellite Configuration)

Overview

The Airs ATS-1200 Intelligent Cryogenic Standard Reference Material Storage Cabinet is an engineered solution for laboratories requiring traceable, temperature-stable custody of certified reference materials (CRMs), pharmacopeial standards, and calibration standards. Designed specifically for the secure storage and controlled access of temperature-sensitive reference substances—particularly those requiring low-temperature preservation—the system integrates precision environmental control with radio-frequency identification (RFID) technology to establish a closed-loop, digitally auditable material lifecycle record. Unlike conventional cold storage cabinets, the ATS-1200 operates on a master-satellite architecture: the master cabinet houses the primary control unit, RFID reader array, and central database interface, while satellite cabinets extend scalable storage capacity with synchronized temperature monitoring and real-time inventory mirroring. Its dual configurable temperature range (–22 °C to –5 °C or 0 °C to 8 °C) complies with ICH Q5C stability guidance for biological reference standards and USP requirements for refrigerated storage of pharmaceutical reference standards.

Key Features

• RFID-enabled automatic check-in/check-out: Passive UHF RFID tags (ISO/IEC 18000-6C compliant) are affixed to standard vials, trays, or secondary packaging; no manual scanning required upon door opening/closing.
• Dual-zone temperature flexibility: Independent compressor-based cooling systems allow field-selectable operation in either cryogenic (–22 °C to –5 °C) or chilled (0 °C to 8 °C) mode—validated per ISO 17025 clause 5.4.3 for thermal uniformity and stability.
• Master-satellite topology: Supports up to four satellite cabinets per master unit, each retaining full sensor autonomy (PT100 RTD probes at multiple spatial points) and synchronized alarm propagation via CAN bus communication.
• Real-time environmental logging: Continuous recording of temperature, door status, humidity (optional sensor), and RFID event timestamps with ≥10-year local data retention and encrypted USB export capability.
• Physical security integration: Electromagnetic door locks with forced-entry detection, tamper-evident audit logs, and role-based access control (RBAC) aligned with FDA 21 CFR Part 11 Annex 11 requirements for electronic records.

Sample Compatibility & Compliance

The ATS-1200 accommodates standard laboratory containers including 2 mL screw-cap vials, 15 mL and 50 mL conical tubes, ISO 8655-compliant pipette tip racks, and custom-insert trays (dimensions up to 320 mm × 280 mm × 120 mm per shelf). All internal surfaces are constructed from electropolished 304 stainless steel with seamless welds to support ISO 14644-1 Class 5 cleanroom-compatible cleaning protocols. The cabinet meets EN 61000-6-3 (EMC emissions), EN 61000-6-2 (immunity), and UL 61010-1 safety standards. Temperature validation reports—including IQ/OQ documentation, mapping studies (per ASTM E2297), and uncertainty budgets—are provided with commissioning. Data integrity workflows align with GLP principles and support inspection readiness for regulatory audits (e.g., WHO TRS 961, EU GMP Annex 15).

Software & Data Management

The integrated Airs InventoryGuard™ software (v4.2+) provides browser-based administration via HTTPS-secured TLS 1.2+ connection. It maintains a relational SQLite database with ACID compliance, supporting automated generation of ALCOA+ compliant records: attributable, legible, contemporaneous, original, accurate, complete, consistent, enduring, and available. Each RFID event triggers timestamped metadata capture—including operator ID (via badge scan or LDAP integration), location (cabinet + shelf + slot), and ambient conditions. Export formats include CSV (for LIMS ingestion), PDF audit packages (with digital signatures), and XML for enterprise ERP synchronization. System-generated alerts—such as temperature excursion (>±0.5 °C for >2 min), unauthorized access attempt, or tag read failure—are routed via SMTP or SNMP to designated lab management platforms.

Applications

• Pharmaceutical QC labs managing USP/EP/JP reference standards under cGMP-controlled environments.
• Contract testing organizations (CTOs) maintaining ISO/IEC 17025-accredited CRM inventories with full chain-of-custody documentation.
• National metrology institutes storing certified reference materials requiring long-term stability verification per ISO Guide 35.
• Academic core facilities supporting multi-user access to shared analytical standards with usage analytics and cost-allocation reporting.
• Biobanks preserving authenticated biological reference materials where thermal history directly impacts assay validity.

FAQ

Does the ATS-1200 support integration with existing LIMS or ELN systems?
Yes—through RESTful API endpoints and configurable HL7/CSV batch import/export modules. Pre-built connectors are available for LabVantage, Thermo Fisher SampleManager, and Benchling.
What is the maximum number of RFID-tagged items the system can track simultaneously?
Each cabinet supports up to 2,000 unique RFID tags with concurrent read capability (EPC Gen2 protocol); total system capacity scales linearly with satellite count.
Is temperature mapping validation included in the installation service?
Yes—comprehensive IQ/OQ including 9-point thermal mapping across all shelves, performed under loaded conditions per ASTM E2297, with final report delivered prior to operational handover.
Can users define custom expiration or retest date rules within the software?
Yes—rules-based workflows allow configuration of auto-alerts, quarantine flags, and automated deactivation of expired standards based on certificate dates, storage duration, or cumulative thermal exposure metrics.
What cybersecurity certifications does the embedded controller firmware hold?
Firmware complies with IEC 62443-4-2 SL2 requirements; includes secure boot, signed firmware updates, and TLS 1.2+ encrypted communications—certified by TÜV Rheinland (Report No. RHE-2023-11847).
