Overview
The AnYuJie HWS-2000 is a large-capacity, microprocessor-controlled temperature and humidity incubator engineered for long-term stability in demanding life science applications. It operates on the principle of forced-air convection combined with ultrasonic humidification and compressor-based refrigeration to maintain precise, independent control of temperature (5–50 °C) and relative humidity (40–95 %RH) within its 2000-liter stainless steel chamber. Unlike water-jacketed systems, the air-jacketed heating architecture enables rapid thermal response while maintaining robust thermal inertia—critical for uninterrupted BOD assays, seed germination studies, microbial cultivation, and environmental stress testing. Its dual-door design minimizes internal parameter drift during frequent access, and the chamber’s uniform airflow pattern—generated by a corrosion-resistant stainless steel circulation duct—ensures spatial consistency across all sample positions, meeting the spatial uniformity requirements defined in ISO 15197 and ASTM E2912 for biological incubation validation.
Key Features
- Ultrasonic humidification system with external water reservoir for consistent, low-maintenance moisture delivery and reduced risk of mineral deposition or microbial carryover
- Air-jacketed heating with programmable ramp-soak profiles and compressor-based cooling featuring high/low pressure protection and delayed startup logic
- Dual-pane observation window with integrated LED lighting for continuous visual monitoring without thermal load disruption
- Microprocessor-based PID controller with independent temperature/humidity setpoint programming, real-time digital display, and user-configurable alarm thresholds
- Stainless steel interior chamber and circulation ductwork compliant with ISO 8573-1 Class 3 for particulate and microbial containment
- Independent over-temperature cutoff and sensor fault detection circuitry—meeting IEC 61010-1 safety requirements for laboratory equipment
Sample Compatibility & Compliance
The HWS-2000 accommodates diverse biological and environmental samples—including Petri dishes, multi-well plates, tissue culture flasks, soil cores, aquatic microcosms, and BOD bottles—within its spacious 2000 L chamber. Its stable 5–50 °C operating range supports mesophilic and thermotolerant organism growth, while the 40–95 %RH range satisfies protocols for fungal propagation, plant tissue culture, and accelerated aging studies per ISO 11784. The unit is designed for use in GLP-compliant laboratories; its controller logs timestamped setpoints and alarms, supporting audit-ready documentation. Though not FDA 21 CFR Part 11–certified out-of-the-box, it permits integration with third-party data acquisition systems that provide electronic signature and audit trail functionality.
Software & Data Management
The embedded controller supports up to 99 programmable cycles with segment-based ramp/soak sequences. While the standard interface is local-only (no built-in Ethernet or USB), optional RS-485 communication enables connection to SCADA or LIMS platforms via Modbus RTU protocol. All operational events—including door-open duration, temperature/humidity excursions, and alarm triggers—are stored in non-volatile memory for retrieval via front-panel navigation. For regulatory environments, users may export logs manually using a serial terminal emulator; raw data exports include ISO 8601 timestamps, parameter values, and event codes—facilitating traceability in QA/QC workflows aligned with ISO/IEC 17025.
Applications
- Biochemical Oxygen Demand (BOD5) analysis per APHA Standard Methods 5210B and ISO 5815-1
- Seed viability and germination testing under controlled hygrothermal stress (ISTA guidelines)
- Microbial enumeration and stability studies for pharmaceutical excipients and probiotic formulations
- Environmental simulation for pesticide degradation, algal bloom dynamics, and sediment toxicity assays
- Long-duration plant phenotyping and tissue culture acclimatization experiments requiring >1000 L working volume
- Pre-conditioning of polymer composites and packaging materials per ASTM D4332 and ISO 2230
FAQ
What is the typical recovery time after door opening?
Under standard conditions (25 °C / 60 %RH), full recovery to setpoint parameters occurs within ≤12 minutes following a 30-second door opening—validated per ISO 15197 Annex C.
Is the humidification system compatible with sterile water or distilled water only?
Yes. Use of deionized or distilled water is mandatory to prevent scaling and ensure ultrasonic transducer longevity. Tap water is not recommended.
Can this incubator be validated for IQ/OQ/PQ protocols?
Yes. The unit provides stable, repeatable setpoint performance and includes calibration-accessible sensor outputs. Full qualification requires third-party probes and documented procedures aligned with GAMP 5.
Does the controller support password-protected parameter modification?
Yes. Three-tier access control (Operator, Supervisor, Administrator) is configurable via keypad lockout settings.
What maintenance intervals are recommended for optimal performance?
Ultrasonic humidifier cleaning every 2 weeks; external water reservoir refill and inspection weekly; compressor condenser coil cleaning quarterly; temperature/humidity sensor verification annually.
