Overview
The Arctiko ULTF Series Horizontal Ultra Low Temperature Freezer is an engineered solution for long-term cryogenic storage of sensitive biological specimens—including primary cells, stem cell lines, plasma, mRNA vaccines, and genomic samples—requiring stable thermal environments between –40 °C and –85 °C. Designed and manufactured in Denmark, this series employs a single-stage high-efficiency refrigeration system optimized for minimal energy consumption and acoustic emissions (<55 dB[A] at 1 m), making it suitable for shared laboratory spaces where operational noise and power load are critical constraints. Unlike vertical upright freezers, the horizontal architecture minimizes cold air loss during frequent access, preserves temperature uniformity across the chamber, and reduces thermal stress on stored vials and cryoboxes during door opening cycles. The unit’s structural integrity is reinforced with vacuum-insulated panels (VIPs) and polyurethane foam insulation, delivering superior thermal retention and reducing compressor cycling frequency—key factors contributing to extended component lifespan and lower total cost of ownership over 10+ years.
Key Features
- Digital microprocessor-based temperature control system with real-time monitoring, programmable setpoints, and ±0.5 °C temperature stability across the full operating range
- Integrated 72-hour battery backup for continuous controller operation and data logging during mains power failure—ensuring uninterrupted thermal oversight and audit-ready event records
- Remote alarm interface supporting SNMP, Modbus RTU, and dry-contact outputs; compatible with centralized lab infrastructure management platforms (e.g., LabVantage, Thermo Fisher SampleManager)
- Optional CO₂ backup cooling module—activates automatically upon primary system fault or sustained ambient temperature rise, maintaining chamber temperature above –70 °C for up to 48 hours without user intervention
- Compact horizontal footprint optimized for space-constrained cleanrooms, BSL-2 labs, and core facilities; ULTF 80 occupies less than 0.36 m² floor area while delivering 71 L usable volume
- Corrosion-resistant stainless steel interior and aluminum-coated evaporator coils; all internal surfaces comply with ISO 14644-1 Class 7 (10,000) particulate limits when operated under controlled ventilation
Sample Compatibility & Compliance
The ULTF Series accommodates standard cryogenic storage formats—including 1.2 mL, 2.0 mL, and 5.0 mL externally threaded cryovials; 10 × 10 and 12 × 12 alphanumeric cryoboxes; and stacked 2D barcode-labeled racks—without requiring custom shelving. Interior chamber geometry ensures unobstructed airflow around all storage positions, validated per ICH Q5C and ISO 20417 for consistent thermal performance. Units are supplied with factory calibration certificates traceable to DKD/DAkkS-accredited standards and conform to EN 61000-6-3 (EMC emission), EN 61000-6-2 (immunity), and IEC 61010-1 (safety). For regulated environments, optional firmware upgrades enable 21 CFR Part 11–compliant electronic signatures, audit trails, and role-based access control—supporting GLP, GCP, and GMP workflows in biobanking, clinical trial logistics, and pharmaceutical development labs.
Software & Data Management
Arctiko’s proprietary ULTConnect software provides secure local and cloud-enabled monitoring via Ethernet or Wi-Fi. It logs temperature, compressor runtime, door-open events, alarm status, and battery health at user-defined intervals (1–60 min), storing >12 months of data locally on encrypted internal flash memory. Data exports are generated in CSV or PDF format with embedded digital signatures and time-stamped metadata compliant with ALCOA+ principles. Integration with third-party LIMS and ELN systems is supported through RESTful API endpoints and configurable webhook triggers—for example, automatic notification to a QC supervisor upon three consecutive temperature excursions exceeding ±2 °C from setpoint. All firmware updates are digitally signed and delivered via HTTPS to prevent unauthorized modification.
Applications
- Cryopreservation of induced pluripotent stem cells (iPSCs) and primary human hepatocytes requiring ≤–80 °C stability for ≥5-year viability retention
- Storage of lipid nanoparticle (LNP)-formulated mRNA therapeutics under WHO-recommended ultra-cold chain conditions (–70 °C ±10 °C)
- Long-term archiving of clinical trial biospecimens in biorepositories accredited to ISO 20387:2018
- Backup storage for central ultra-low temperature facilities during maintenance or redundancy planning
- On-site storage of reference standards and certified reference materials (CRMs) used in ISO/IEC 17025–accredited testing laboratories
FAQ
What is the recommended preventive maintenance schedule for the ULTF Series?
Arctiko recommends quarterly visual inspection of door gaskets and condenser coil cleaning, plus annual verification of temperature uniformity (per ISO 14644-3 Annex B) and calibration of the primary Pt100 sensor by an authorized service technician.
Can the ULTF freezer be installed in non-air-conditioned environments?
Ambient operating conditions must remain between +10 °C and +32 °C with relative humidity ≤60% non-condensing; installation outside this range voids warranty and compromises temperature stability and compressor longevity.
Is remote firmware update capability available out-of-the-box?
Yes—firmware version 3.2.1 and later support over-the-air updates via secure TLS 1.2 connection; updates require administrator-level credentials and generate immutable log entries for compliance auditing.
Does the CO₂ backup system require external gas supply or cylinder integration?
The integrated CO₂ module uses a self-contained, pre-charged cartridge with 5-year shelf life; no external plumbing, regulators, or gas cylinders are required for standard deployment.
How is temperature mapping performed during qualification?
Arctiko provides IQ/OQ documentation templates aligned with ASTM F2697–21 and EU GMP Annex 15; users may conduct mapping using calibrated NIST-traceable thermistors (≥15 probes) placed at defined geometric locations, with data analyzed using included validation software modules.
