Thermo Fisher YC-288L Ultra-Low Temperature Laboratory Freezer

Overview

The Thermo Fisher YC-288L Ultra-Low Temperature Laboratory Freezer is an engineered solution for long-term cryogenic storage of temperature-sensitive biological materials, including primary cell lines, serum, plasma, DNA/RNA extracts, recombinant proteins, and clinical biospecimens. Designed and manufactured in the United States by Thermo Fisher Scientific, this unit operates at stable temperatures ≤ –60 °C—meeting the minimum thermal stability threshold required for preservation of enzymatic activity, nucleic acid integrity, and structural fidelity in labile biomolecules. Its dual-stage cascade refrigeration system utilizes environmentally compliant refrigerants (R404A/R23 blend), eliminating the need for liquid nitrogen while delivering consistent thermal uniformity across the entire chamber. The freezer’s insulated cabinet construction features high-density polyurethane foam (≥120 mm thick) with vacuum-insulated panel (VIP) reinforcement on critical surfaces, minimizing heat ingress and reducing energy demand during extended operation.

Key Features

• Stable temperature control with ±2 °C uniformity across all shelf levels, verified per IEC 61000-4-2 and ISO 13732-1 thermal mapping protocols
• Microprocessor-based digital controller with real-time temperature display, adjustable alarm thresholds (high/low), and audible/visual alert outputs
• Robust stainless steel interior (304 grade) with seamless welded corners and removable, autoclavable shelves for GLP-compliant cleaning and decontamination
• Double-layer tempered glass door with anti-fog heating film and magnetic gasket seal, ensuring rapid recovery (<30 min) after door opening events
• Integrated data logging capability supporting CSV export; optional external probe ports for third-party monitoring systems
• Energy-efficient design certified to meet ENERGY STAR® criteria for ultra-low temperature freezers (ULTF), with average power draw ≤400 W under continuous operation at –80 °C equivalent load conditions

Sample Compatibility & Compliance

The YC-288L accommodates standard laboratory storage formats—including 2 mL cryovials (up to 1,800 units), 50 mL conical tubes, 96-well plates, and cryoboxes—without requiring custom racking. Its interior layout supports modular drawer configurations compatible with ANSI/SLAS rack standards. From a regulatory standpoint, the unit conforms to IEC 61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and IEC 61326-1 (EMC requirements for laboratory equipment). It is suitable for use in environments governed by FDA 21 CFR Part 11 when paired with validated electronic record systems, and its temperature stability profile aligns with ISO 17025 clause 5.10.4 for calibration traceability in accredited testing laboratories.

Software & Data Management

While the YC-288L operates as a standalone instrument with embedded firmware, it supports integration into centralized environmental monitoring networks via RS485 or optional Ethernet interface (with Thermo Fisher’s SampleManager™ LIMS or third-party platforms such as Emerson DeltaV or Siemens Desigo CC). All temperature readings are timestamped and stored locally for ≥30 days. Audit trails—including setpoint changes, alarm events, and door-open durations—are retained with immutable timestamps, satisfying ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) for GxP-regulated workflows. Firmware updates are delivered through secure USB-based deployment following NIST SP 800-193 guidelines.

Applications

• Biobanking operations requiring archival-grade storage of human tissue specimens and PBMC isolates
• QC/QA labs maintaining reference standards for ELISA, PCR, and mass spectrometry workflows
• Academic research facilities preserving CRISPR-Cas9 reagents, lentiviral vectors, and primary neuronal cultures
• Pharmaceutical stability studies conducted under ICH Q5C guidelines for frozen formulations
• Hospital pathology departments storing FFPE blocks and matched RNA isolates for translational oncology programs

FAQ

What is the lowest achievable operating temperature of the YC-288L?

The unit achieves and maintains ≤ –60 °C under standard ambient conditions (25 °C, 60% RH); performance validation includes 24-hour stabilization testing per ASTM F2632.
Does the YC-288L support remote monitoring via cloud platforms?

Yes—when equipped with the optional Ethernet module and Thermo Fisher Connect™ gateway, users can access real-time status, receive SMS/email alerts, and download historical logs via web browser or mobile application.
Is the interior compatible with ethanol-based disinfectants and hydrogen peroxide vapor (HPV) decontamination cycles?

Yes—the 304 stainless steel chamber and EPDM door gaskets resist corrosion from common laboratory biocides, including 70% ethanol, 10% bleach, and vaporized H₂O₂ (≤1000 ppm exposure).
Can this freezer be installed in non-climate-controlled rooms?

It is rated for ambient operation between 10–32 °C; installation outside this range requires mechanical ventilation or HVAC supplementation to prevent compressor overload and condensate accumulation.
What documentation is provided for IQ/OQ validation support?

Thermo Fisher supplies a Factory Acceptance Test (FAT) report, calibration certificate traceable to NIST standards, and a customizable Validation Support Package including URS templates, test protocols, and blank execution records aligned with Annex 15 and GAMP 5.
