Overview
The Thermo Scientific Revco ExFGP Series Ultra-Low Temperature Freezer is an engineered solution for long-term, stable cryogenic storage of biological samples—including primary cells, stem cells, plasma, tissue specimens, and nucleic acid extracts—at sustained temperatures of –80 °C. Designed and manufactured in the United States by Thermo Fisher Scientific, the ExFGP series employs a robust cascade refrigeration system featuring high-efficiency industrial-grade compressors, optimized refrigerant circuitry, and intelligent thermal load management. This architecture ensures rapid pull-down times, minimal temperature fluctuation (< ±2 °C at setpoint under standard operating conditions), and consistent thermal uniformity across the entire chamber—critical parameters for preserving sample integrity in regulated research and clinical biobanking environments.
Key Features
- Triple-point door gasket system with integrated magnetic sealing and compression geometry to minimize cold air leakage and maximize energy efficiency.
- Vacuum-relief pressure equalization port enabling rapid, low-effort door reopening after extended closed intervals—eliminating vacuum lock without compromising insulation integrity.
- Choice of interior construction: electropolished stainless steel or zinc-coated steel, both corrosion-resistant and compatible with common laboratory decontamination protocols (e.g., 70% ethanol, sodium hypochlorite).
- Microprocessor-based temperature controller with dual-sensor redundancy, real-time monitoring, and adjustable alarm thresholds for high/low temperature, door open, power failure, and compressor fault.
- Robust structural frame with reinforced cabinet walls and high-density polyurethane foam insulation (≥120 mm thick) meeting ASTM C177 thermal conductivity standards for cryogenic enclosures.
- Integrated casters with locking brakes and front leveling feet for secure, ergonomic placement in ISO Class 7–8 cleanrooms or GMP-compliant laboratory suites.
Sample Compatibility & Compliance
The ExFGP series supports standardized sample storage configurations including 2-inch cryoboxes (up to 200 boxes), rack-based vial systems (1.2–2.0 mL formats), and cryo-tubes compliant with ANSI/SLAS standards. Its chamber layout accommodates both vertical and horizontal access workflows. From a regulatory standpoint, the freezer’s hardware design and firmware architecture support compliance with Good Laboratory Practice (GLP) and Good Manufacturing Practice (GMP) requirements. Data logging capabilities—including timestamped temperature records, alarm events, and user-access logs—can be configured to align with FDA 21 CFR Part 11 electronic record and signature guidelines when paired with Thermo Fisher’s optional Traceable™ software suite.
Software & Data Management
While the base ExFGP model operates via a local LCD interface, it features RS-485 and optional Ethernet connectivity for integration into centralized environmental monitoring systems (EMS). When equipped with Thermo Fisher’s optional Revco Connect™ module, users gain remote access to real-time chamber status, configurable email/SMS alerts, historical trend visualization, and audit-trail generation. All logged data are stored in encrypted, tamper-evident binary files compliant with ISO/IEC 17025 data integrity requirements. Firmware updates are delivered via secure HTTPS channels and validated through cryptographic checksum verification prior to installation.
Applications
- Long-term archiving of human biospecimens in academic biorepositories and NIH-funded cohort studies.
- Cold chain continuity for cell therapy manufacturing facilities operating under cGMP Annex 1 and ICH Q5D guidelines.
- Stabilization of thermolabile reagents, monoclonal antibodies, and viral vectors during preclinical development.
- Backup storage for critical reference standards used in clinical diagnostics laboratories accredited to CLIA and CAP standards.
- Supporting ISO 13485-certified medical device R&D labs requiring documented thermal stability validation for shelf-life testing.
FAQ
What is the typical temperature recovery time after a 30-second door opening event?
Under standard ambient conditions (22 °C, 50% RH), the ExFGP series recovers to within ±1 °C of –80 °C setpoint in ≤12 minutes following a single 30-second door opening with full chamber loading.
Is the unit suitable for installation in non-air-conditioned server rooms or basement laboratories?
Yes—the ExFGP series is rated for ambient operation between 10 °C and 32 °C per IEC 60068-2-1/2 environmental test standards; however, optimal performance and compressor longevity require ambient humidity <75% RH and adequate rear/side clearance (≥100 mm) for heat dissipation.
Can the internal temperature sensor be calibrated onsite by the user?
No—sensor calibration requires traceable NIST-certified reference equipment and must be performed by authorized Thermo Fisher service engineers during scheduled preventive maintenance visits.
Does the freezer meet UL 61010-1 and CE marking requirements for laboratory equipment?
Yes—each ExFGP unit carries full UL 61010-1 certification and CE marking under the EU Machinery Directive 2006/42/EC and Electromagnetic Compatibility Directive 2014/30/EU.
