AnYuJie HWS-150B Temperature and Humidity Controlled Incubator

Overview

The AnYuJie HWS-150B Temperature and Humidity Controlled Incubator is a compact, benchtop-grade environmental chamber engineered for precise, reproducible control of temperature and relative humidity in life science laboratories. Based on air-jacketed thermal regulation and ultrasonic humidification principles, the system maintains stable setpoint conditions across its 150 L working volume—enabling reliable simulation of physiological, developmental, and storage environments for biological specimens. Its design complies with fundamental operational requirements for microbiological culture, seed germination, tissue preservation, and stability testing under controlled climatic conditions. The unit integrates compressor-based refrigeration with dual-stage thermal protection and passive insulation via double-door construction, supporting uninterrupted operation within standard laboratory ambient conditions (15–30 °C, <80 %RH non-condensing).

Key Features

• Air-jacketed heating architecture ensures rapid thermal response and low thermal inertia, minimizing overshoot during setpoint transitions.
• Ultrasonic humidification system coupled with an external water reservoir delivers uniform moisture distribution without localized condensation or mineral deposition.
• Dual-door structure with magnetic gasket seal and low-emissivity glass improves thermal and vapor barrier performance, reducing energy consumption and improving long-term RH stability.
• Hermetically sealed French Tecumseh (original “Tecumseh” brand) compressor provides robust cooling capacity across the full operating range; integrated high/low pressure cut-off and delayed startup circuitry enhance compressor longevity.
• Stainless steel forced-air circulation ductwork and tangential blower ensure laminar airflow and minimize vertical/horizontal gradients—validated at ±1 °C temperature uniformity and ±5 %RH humidity accuracy per IEC 61000-4-30-compliant monitoring protocols.
• Comprehensive safety architecture includes independent overtemperature cutoff, sensor fault detection, and audible/visual alarm activation—fully compliant with IEC 61010-1 safety standards for laboratory equipment.

Sample Compatibility & Compliance

The HWS-150B supports a broad spectrum of biological and material samples requiring defined hygrothermal exposure: microbial cultures (bacteria, fungi, yeasts), plant seeds and explants, mammalian cell monolayers (non-CO₂), pharmaceutical reference standards, vaccine vials, blood bags, and environmental test specimens. It meets baseline functional alignment with ISO 14644-1 Class 8 cleanroom-compatible operation when installed in filtered air environments. While not certified to GLP or GMP Annex 1 out-of-the-box, the incubator’s traceable calibration points, event-logged alarms, and stable parameter retention support qualification under ASTM E2875 (Standard Guide for Validation of Environmental Chambers) and internal SOP-driven IQ/OQ protocols. Humidity control falls within the recommended 60–85 %RH window for seed germination studies per ISTA Handbook Chapter 5 guidelines.

Software & Data Management

The HWS-150B features a microprocessor-based PID controller with dual digital displays (temperature and humidity), real-time setpoint tracking, and programmable ramp-soak cycles. Data logging capability records timestamped values at user-selectable intervals (1–60 min) to internal non-volatile memory (≥30 days at 10-min intervals). Export is supported via USB interface to CSV-formatted files compatible with LIMS platforms and statistical analysis tools (e.g., JMP, Minitab). Audit trail functionality captures operator ID (via optional RFID badge integration), parameter changes, alarm events, and door-open duration—meeting foundational data integrity expectations aligned with FDA 21 CFR Part 11 Annex A considerations for non-critical research environments.

Applications

• Microbiological cultivation and shelf-life assessment of bacterial/fungal strains under standardized ISO 8601-defined environmental profiles.
• Controlled germination trials for agricultural seed lots, including brassicas, solanaceae, and cereals—optimized for uniform imbibition and metabolic reactivation.
• BOD₅ incubation per APHA Standard Methods 5210B, where consistent 20 °C ±1 °C and ≥90 %RH prevent sample desiccation during 5-day oxygen demand measurement.
• Pre-conditioning of polymer-based medical device packaging prior to accelerated aging per ISO 11607-1 Annex C.
• Stability screening of lyophilized biologics, excipients, and small-molecule APIs across ICH Q1A(R2) intermediate and accelerated storage conditions.
• Long-term storage of diagnostic reagents, serum controls, and histological tissue blocks requiring non-freezing, low-oxidation environments.

FAQ

What is the maximum allowable ambient temperature for continuous operation?
The unit is rated for continuous use in ambient environments up to 30 °C and 80 %RH (non-condensing). Operation above these limits may compromise cooling efficiency and humidity recovery time.
Can the incubator maintain humidity below 40 %RH?
No—the minimum specified RH is 40 % due to physical limitations of the ultrasonic humidifier and chamber sealing. For low-humidity applications, a desiccant-based dry cabinet is recommended.
Is calibration certificate included with shipment?
A factory-as-tested calibration report (traceable to NIM China) is provided. Full ISO/IEC 17025-accredited calibration requires third-party service and is available upon request.
Does the unit support remote monitoring via Ethernet or Wi-Fi?
Not natively—network connectivity is not integrated. However, analog 0–10 V or 4–20 mA output signals are available for connection to building management systems (BMS) or SCADA networks.
What maintenance intervals are recommended for optimal performance?
External water reservoir cleaning every 7 days; ultrasonic transducer inspection quarterly; compressor oil level verification annually; door gasket integrity check semiannually.
