Eppendorf CryoCube FC660h Horizontal Ultra-Low Temperature Freezer

Overview

The Eppendorf CryoCube FC660h is a high-performance horizontal ultra-low temperature (ULT) freezer engineered for long-term, stable cryopreservation of sensitive biological samples—including primary cells, stem cell lines, genomic DNA, RNA, proteins, and clinical biobank specimens. Operating at a nominal setpoint of –86 °C, the system employs a cascade refrigeration architecture with environmentally optimized HFC-free refrigerants (R290/R170), delivering thermodynamic stability without compromising regulatory compliance or sustainability goals. Its compact footprint (2050 mm width × 785 mm depth × 1092 mm height) and front-access horizontal design maximize usable lab floor space while enabling ergonomic sample retrieval—critical in high-throughput academic core facilities, pharmaceutical QC labs, and GMP-aligned biobanking operations.

Key Features

• Cascade Cooling System: Dual-stage compressor circuitry ensures rapid cooldown (≤5.8 hours from 25 °C to –85 °C) and maintains ±0.5 °C temperature uniformity across the entire 760 L chamber volume, verified per IEC 60068-3-5 thermal mapping protocols.
• Thermal Integrity Engineering: 30 mm thick molded polyurethane insulation in both cabinet walls and inner lid minimizes thermal bridging; combined with a dual-loop silicone door gasket featuring micro-contoured sealing geometry to suppress frost accumulation and sustain vacuum-tight closure at –86 °C.
• Energy-Efficient Operation: Consumes only 16 kWh/day at –80 °C setpoint—approximately 30% below industry median for comparable 700–800 L ULT freezers—validated under ISO 15095:2017 energy performance testing conditions.
• Secure Access & Audit Readiness: Password-protected interface restricts modification of temperature setpoints, alarm thresholds, and logging parameters—supporting GLP/GMP documentation requirements and facilitating FDA 21 CFR Part 11-compliant electronic record workflows when integrated with Eppendorf’s CryoCube Connect software.
• Deployment-Optimized Design: Factory-installed heavy-duty slide rails allow safe, floor-level rolling deployment from shipping pallets without lifting equipment—reducing installation risk and minimizing downtime during facility commissioning.
• Low-Noise Acoustics: Optimized fan speed modulation and vibration-dampened compressor mounting achieve ≤48 dB(A) operational noise, permitting placement in shared laboratory corridors or near sensitive instrumentation without interference.

Sample Compatibility & Compliance

The CryoCube FC660h accommodates standard cryogenic storage configurations including 2-inch and 5-inch cryoboxes (up to 200 boxes), rack-based vial systems (e.g., 1.2 mL, 2.0 mL, and 5.0 mL formats), and large-volume cryobags (up to 500 mL). Internal dimensions (1560 × 625 × 780 mm) support full-height stacking of ISO-standard 400 mm-deep racks. The unit complies with IEC 61010-1 (Safety Requirements for Electrical Equipment), IEC 60335-2-24 (Particular Requirements for Refrigerating Appliances), and carries CE marking for the European Economic Area. Optional validation packages include IQ/OQ documentation aligned with ISO/IEC 17025 and ASTM E2500-13 for qualification in regulated environments.

Software & Data Management

When paired with Eppendorf CryoCube Connect (v3.2+), the FC660h enables remote monitoring via Ethernet or Wi-Fi, real-time temperature trending, configurable SMS/email alerts for deviation events, and automated export of audit-trail-enabled log files in CSV or PDF format. All data entries—including user login IDs, timestamped parameter changes, and alarm acknowledgements—are cryptographically signed and retained for ≥36 months, satisfying traceability mandates under ISO 13485, USP , and EU Annex 11 for computerized system validation.

Applications

• Long-term archiving of human tissue samples in biorepositories accredited to ISBER Best Practices.
• Stabilization of temperature-sensitive monoclonal antibodies and viral vectors during process development and fill-finish staging.
• Storage of CRISPR-Cas9 ribonucleoprotein complexes and base-editing reagents requiring sustained –80 °C integrity.
• Backup cold chain assurance for clinical trial biospecimens subject to CLIA/CAP inspection criteria.
• Support of ISO/IEC 17025-accredited reference material storage in metrology laboratories.

FAQ

What is the minimum ambient temperature required for stable operation?
The CryoCube FC660h is rated for continuous operation in ambient environments between 10 °C and 32 °C, with derating applied above 25 °C per IEC 60068-3-4 specifications.
Does the unit support external temperature monitoring integration?
Yes—via optional 4–20 mA analog output or Modbus RTU over RS-485, enabling connection to building management systems (BMS) or centralized environmental monitoring platforms (e.g., SensiNet, TempTrak).
Is the inner chamber stainless steel or coated carbon steel?
The interior liner is electropolished AISI 304 stainless steel, certified to EN 10088-1 for corrosion resistance and compatibility with ethanol-based decontamination protocols.
Can the freezer be validated for use in GxP-regulated workflows?
Yes—Eppendorf provides prequalified IQ/OQ protocols, calibration certificates traceable to NIST standards, and on-site validation support through certified field service engineers.
What is the warranty coverage and service response time?
Standard warranty is 24 months parts and labor; extended service agreements include 4-hour emergency response for critical failures in EMEA regions, subject to contract terms.
