Overview
The Maikenuo HSX-250 Temperature and Humidity Controlled Incubator is a precision-engineered environmental chamber designed for stable, long-term cultivation and conditioning of biological samples under tightly regulated thermal and hygroscopic conditions. Utilizing dual independent PID-controlled heating, refrigeration, and humidification systems, the incubator maintains consistent setpoints across its 250 L working chamber—enabling reproducible experimental outcomes in cell culture, microbial growth, seed germination, stability testing, and environmental simulation protocols. Its architecture conforms to fundamental requirements for GLP-compliant laboratory environments, supporting applications aligned with ISO 17025-accredited workflows and regulatory documentation needs in academic, pharmaceutical, and biotechnology settings.
Key Features
- Microprocessor-based dual-loop control system for simultaneous temperature and humidity regulation, featuring LED digital display with real-time parameter monitoring and intuitive touch-key interface.
- Stainless steel interior chamber with seamless welded corners and electropolished finish—optimized for cleanability, corrosion resistance, and low particulate generation.
- High-efficiency polyurethane foam insulation (≥60 mm thickness) integrated into double-wall construction, minimizing thermal bridging and enhancing energy efficiency.
- Optimized air circulation design with rear-mounted centrifugal blower and perforated stainless steel shelf supports—ensuring uniform temperature distribution (±1 °C) and minimal vertical/horizontal gradients.
- Double-layer tempered glass observation door with anti-fog coating and internal LED illumination—enabling non-invasive sample monitoring without compromising chamber integrity.
- Compressor protection circuitry including power interruption delay (3-minute restart lockout) and over-temperature/over-humidity safety cutoffs—extending system longevity and operational reliability.
Sample Compatibility & Compliance
The HSX-250 accommodates standard-sized culture vessels—including Petri dishes, multi-well plates, flasks (up to 2 L), and tissue culture stacks—on three adjustable stainless steel shelves. Its interior dimensions (W×D×H: 550 × 450 × 1000 mm) allow flexible load configurations while maintaining airflow integrity. The unit meets essential safety and performance benchmarks for laboratory equipment, including IEC 61010-1 (Electrical Safety for Laboratory Equipment) and EN 60335-1 (Household and Similar Electrical Appliances). While not certified for GMP manufacturing environments, its design supports audit-ready documentation practices required under FDA 21 CFR Part 11 when paired with validated external data loggers or optional RS-485/Modbus-enabled controllers.
Software & Data Management
The incubator operates as a standalone analog-digital hybrid platform with no embedded software stack. However, it features analog voltage outputs (0–5 V DC) for temperature and humidity signals—compatible with third-party data acquisition systems (e.g., LabVIEW, WinCC, or custom SCADA platforms) for continuous logging, trend analysis, and alarm integration. Optional upgrade kits include USB-connected temperature/humidity data loggers compliant with ISO/IEC 17025 traceable calibration standards, enabling automated CSV export and timestamped event reporting suitable for quality assurance records. All operational parameters are retained in non-volatile memory during brief power interruptions.
Applications
- Cell and tissue culture maintenance under physiological conditions (e.g., 37 °C / 95 %RH for mammalian monolayers).
- Microbial growth studies requiring controlled moisture levels—such as fungal sporulation assays or bacterial biofilm development at sub-saturated RH.
- Plant physiology experiments involving stratification, vernalization, or drought stress simulation via programmable RH ramping.
- Stability testing per ICH Q1A(R2) guidelines for pharmaceutical intermediates exposed to intermediate climate zones (e.g., 30 °C / 65 %RH).
- Environmental simulation for material degradation studies—particularly polymer hygroscopic swelling or adhesive curing kinetics.
- Educational use in undergraduate life science laboratories for teaching principles of homeostasis, enzyme kinetics, and environmental physiology.
FAQ
Does the HSX-250 support programmable ramp-and-soak cycles?
No—the unit operates in static setpoint mode only. For time-dependent environmental profiles, integration with an external programmable controller is required.
Is the stainless steel chamber electropolished to ISO 15693 standards?
The interior surface is passivated and electropolished to meet ASTM A967 for corrosion resistance; full ISO 15693 compliance applies only to specialized cleanroom-grade variants.
Can this incubator be used for CO₂-sensitive cultures?
No—this model lacks CO₂ injection, sensing, or pH-buffering capabilities. It is strictly a temperature/humidity control platform.
What is the recommended calibration interval for traceable operation?
Annual verification using NIST-traceable dry-block calibrators (for temperature) and chilled-mirror hygrometers (for RH) is advised per ISO/IEC 17025 Clause 6.6.
Is remote monitoring supported out of the box?
Not natively—but analog output signals enable connection to industrial IoT gateways or building management systems (BMS) via Modbus RTU or 4–20 mA transducers.
