DreamLab DL-RC60S / DL-RC120S Self-Cleaning Refrigerated Medicine Cabinet

Overview

The DreamLab DL-RC60S and DL-RC120S Self-Cleaning Refrigerated Medicine Cabinets are engineered for secure, contamination-controlled storage of temperature-sensitive reagents, pharmaceuticals, and hazardous chemicals in regulated laboratory and clinical environments. Unlike conventional ambient or refrigerated cabinets, these units integrate active air recirculation with multi-stage gas-phase filtration and precise cold-chain management (2–8 °C). The core operating principle combines thermoelectric or compressor-based refrigeration with a unidirectional, low-turbulence airflow path—designed to isolate stored materials from ambient lab air while continuously purifying internal cabinet air. Air enters exclusively through a bottom-mounted intake, passes vertically across all storage shelves, and exits at the top through a sealed filtration module. This laminar flow architecture prevents cross-contamination between samples and ensures consistent thermal and chemical stability throughout the chamber.

Key Features

• Refrigerated operation at 2–8 °C with ±0.5 °C temperature uniformity (per IEC 61000-4-2 validated stability profile)
• Dual-path air purification system: electrostatic pre-filter (G4 class, ≥90% efficiency for particles >5 µm) + bonded activated carbon filter (coconut-shell derived, chemically impregnated variants available for H₂S, NH₃, Cl₂, formaldehyde, and sulfur compounds)
• Optional HEPA (H13) particulate filter for aerosol and microbial containment (meets ISO 14644-1 Class 5 requirements when installed)
• 1.0 mm cold-rolled steel construction with epoxy-polyester powder coating—resistant to common laboratory solvents including acetone, ethanol, and 10% NaOH
• Auto-return tempered glass door with magnetic seal and aluminum frame—ensures zero bypass leakage and maintains airflow integrity
• DLTouch controller with DLOS (DreamLab Operating System): real-time monitoring of fan RPM (% of max speed), filter saturation status, internal temperature/humidity, cumulative runtime, and energy consumption
• Filter life tracking with configurable alert thresholds (audible + visual) and automatic reset via QR-coded filter ID input

Sample Compatibility & Compliance

These cabinets support storage of volatile organic compounds (VOCs), corrosive acids/bases, cytotoxic agents, and light-sensitive formulations without degradation or off-gassing accumulation. Designed for compliance with GLP and GMP-aligned workflows, the unit supports audit-ready documentation: full event logging (including door openings, temperature excursions, and filter replacement events) meets FDA 21 CFR Part 11 data integrity requirements when paired with optional networked reporting modules. Filter performance aligns with ASTM D5207 (standard test method for evaluating gas-phase air cleaners) and ISO 10121-1 (gas-phase filtration for general ventilation). Structural design conforms to EN 14470-1 (fire-resistant safety cabinets) for incidental thermal exposure up to 10 minutes at 900 °C.

Software & Data Management

The DLOS platform runs on an embedded ARM Cortex-A9 processor with 5.7″ capacitive touchscreen interface. All operational parameters—including setpoint temperature, fan speed profile, alarm thresholds, and user access levels—are configurable via a single-tier settings menu. Filter management is fully traceable: each installed filter carries a unique 8-digit alphanumeric ID; scanning or manual entry resets its lifetime counter and logs installation date/time. Historical data (last 30 days of temperature, humidity, fan load, and filter delta-P) is exportable via USB-C port in CSV format. Optional Ethernet/Wi-Fi connectivity enables integration into centralized lab infrastructure management systems (LIMS or BMS) using Modbus TCP or MQTT protocols.

Applications

• Stabilized storage of enzyme solutions, monoclonal antibodies, and oligonucleotides requiring both low temperature and VOC-free atmosphere
• Secure containment of halogenated solvents (e.g., chloroform, carbon tetrachloride) and aldehydes (e.g., glutaraldehyde) in histopathology and microbiology labs
• Compliance-driven storage of controlled substances (Schedule II–IV) under DEA and EU Annex 13 requirements
• Pre-analytical sample staging in clinical chemistry and toxicology laboratories where ambient air contaminants may interfere with LC-MS/MS or ICP-MS analysis
• Long-term archiving of reference standards and certified reference materials (CRMs) per ISO/IEC 17025 clause 7.6.2

FAQ

What is the recommended replacement interval for the pre-filter?
Pre-filters should be replaced every 3 months under continuous operation; however, the DLTouch controller dynamically adjusts this recommendation based on actual particulate loading and fan pressure differential.
Can the cabinet operate without the activated carbon filter installed?
No—the system will not initiate refrigeration cycle if the main gas-phase filter is absent or improperly seated, as confirmed by integrated mechanical interlock switches.
Is remote monitoring supported out of the box?
Standard units include local USB-C data export; remote telemetry requires optional communication module (DLOS-Net v2.1) and configuration via DHCP or static IP assignment.
Does the unit comply with UL or CE safety standards?
Yes—certified to IEC 61010-1:2010 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and EMC compliant per IEC 61326-1:2020.
How is temperature uniformity verified across the chamber?
Factory calibration includes 9-point mapping (per ISO/IEC 17025 Annex A.3) using NIST-traceable PT100 probes; certificate provided with each unit.
