Zhongke Meiling YC-260L & YC-360L 2–10°C Medical Refrigerated Storage Cabinet (Brochure Model: YC-Series Vertical Pharmacy & Sample Preservation Unit)

Overview

The Zhongke Meiling YC-Series 2–10°C Medical Refrigerated Storage Cabinets are engineered for precise, stable, and compliant cold-chain preservation of temperature-sensitive biological specimens, pharmaceuticals, vaccines, reagents, and clinical samples in laboratory, pharmacy, and clinical trial environments. Designed to meet the stringent thermal stability requirements of WHO PQS, USP , and ISO 14644-1 Class 8 cleanroom-adjacent applications, these vertical cabinets employ forced-air circulation to ensure uniform temperature distribution (±0.5°C uniformity across load zone) and rapid recovery (<15 min to return to setpoint after 60-sec door opening). Unlike static-cool units, the fan-assisted airflow mitigates stratification and supports consistent storage conditions even under partial or full loading—critical for GLP/GMP-aligned sample integrity management.

Key Features

• 155 mm thick high-density polyurethane insulation with proprietary secondary foaming technology—minimizes thermal bridging and prevents cold leakage at joints and seams, achieving U-value ≤0.22 W/m²·K
• Imported high-efficiency hermetic compressor paired with German ebm-Papst axial fans for low-noise, continuous-duty operation and extended service life
• Pt100 platinum resistance temperature sensor (IEC 60751 Class A) mounted in air stream path for real-time, high-fidelity monitoring with ±0.2°C accuracy
• Dual-door design: outer tempered glass door with anti-fog coating and inner solid insulated door—reduces radiant heat ingress and improves energy efficiency by >25% vs. single-door configurations
• Adjustable wire shelving system (3–5 tiers, load-rated to 25 kg per shelf) with smooth-sliding rails and non-slip surface finish for secure vial, box, and tray placement
• Comprehensive alarm architecture: configurable thresholds for high/low temperature deviation, door-open duration (>30 sec), filter blockage, power interruption, and internal battery status—all logged with timestamps
• Keypad lock and multi-level password protection (administrator/operator modes) to prevent unauthorized parameter changes per FDA 21 CFR Part 11 audit trail readiness

Sample Compatibility & Compliance

These cabinets support long-term storage of primary and secondary standards, QC reference materials, monoclonal antibodies, enzyme solutions, nucleic acid extracts, and lyophilized preparations requiring strict 2–10°C thermal control. The interior chamber is constructed from electropolished stainless steel (AISI 304), corrosion-resistant and compatible with routine disinfection using 70% ethanol or hydrogen peroxide vapor (HPV). Units comply with IEC 61000-6-3 (EMC emissions), IEC 61000-6-2 (immunity), and GB/T 20154–2014 (Chinese national standard for medical refrigerators). Optional validation packages include IQ/OQ documentation templates aligned with ISO/IEC 17025 and GAMP 5 guidelines.

Software & Data Management

The embedded microcontroller supports RS-485 Modbus RTU communication for integration into centralized lab infrastructure monitoring systems (e.g., LabVantage, Thermo Fisher SampleManager). Optional USB-enabled thermal printer provides hard-copy temperature logs with date/time stamp, operator ID, and alarm event annotation. Internal memory retains ≥30 days of 10-minute interval temperature history with cyclic overwrite; external SD card logging (up to 32 GB) enables extended trending analysis. All data exports conform to CSV format for traceability and regulatory submission readiness.

Applications

• Vaccine storage in hospital pharmacies and immunization centers (per CDC Vaccine Storage and Handling Toolkit)
• Stabilization of ELISA kits, lateral flow assay components, and diagnostic reagents prior to use
• Short-to-medium term holding of freshly isolated PBMCs, plasma aliquots, and tissue biopsies pre-cryopreservation
• Storage of calibration standards and reference controls in clinical chemistry and hematology labs
• Backup cold storage for chromatography mobile phases and HPLC column conditioning solvents
• Secure retention of investigational medicinal products (IMPs) during Phase I–III clinical trials under ICH-GCP Annex 13 requirements

FAQ

What is the recommended ambient operating environment for this cabinet?
Rated for use in rooms maintained at 16–32°C and ≤70% RH (Climate Class N per IEC 60068-1). Avoid direct sunlight, HVAC vents, or proximity to heat-generating equipment.
Can the cabinet be validated for GxP compliance?
Yes—factory-installed sensors and data logging capability support IQ/OQ execution. Validation protocols and calibration certificates (NIST-traceable) are available upon request.
Is remote monitoring supported out-of-the-box?
Standard RS-485 interface enables connection to BMS or SCADA systems; Ethernet/WiFi modules are available as field-installable options.
How often does the air filter require maintenance?
The front-access particulate filter should be inspected monthly and cleaned or replaced quarterly depending on lab dust levels.
Does the unit meet energy efficiency standards for public procurement?
Certified to China Energy Label Level 2 (GB 12021.2–2015) and qualifies for ENERGY STAR® equivalent incentive programs in APAC markets.
