Zhicheng ZXJD-A1160 Mold Incubator with Observation Window

Overview

The Zhicheng ZXJD-A1160 Mold Incubator with Observation Window is a precision-engineered environmental chamber designed specifically for controlled fungal culture, microbial maintenance, and long-term stability testing of biological samples under regulated temperature and humidity conditions. Built upon fuzzy logic control architecture, the unit delivers high reproducibility in maintaining setpoint environments—critical for mycological studies, pharmaceutical stability trials (e.g., BOD analysis, spore germination assays), and GLP-compliant strain preservation. Unlike general-purpose incubators, this model integrates dual-stage humidity management (dry-wet and constant-humidity modes), making it suitable for both hyphal growth optimization and desiccation-sensitive culture protocols. Its 160 L working volume, combined with an optimized air circulation system featuring a turbofan-driven forced convection path and geometrically refined chamber geometry, ensures ≤±1 °C uniformity at 37 °C and ≤±0.5 °C temperature fluctuation—meeting essential performance benchmarks for ISO 14644-1 Class 7 cleanroom-adjacent applications and USP environmental qualification requirements.

Key Features

• Fuzzy logic microprocessor control system enabling precise, adaptive regulation of temperature and humidity without manual recalibration
• 10-segment, 18-step programmable cycle function supporting complex multi-phase incubation protocols—including ramp-and-soak, stepwise gradient, and repetitive cycling
• High-sensitivity integrated temperature/humidity sensor with 0.1 °C resolution and real-time feedback compensation
• Intelligent frost-free refrigeration system using R134a refrigerant with power-modulated cooling capacity (optional configuration)
• Two-stage automatic water replenishment design: primary reservoir + secondary storage tank eliminates manual refilling during extended operation
• Double-door structure with tempered glass inner door and insulated observation window (Φ50 mm test port included) for non-invasive monitoring without thermal or humidity disturbance
• Mirror-finish stainless steel interior (electropolished shelves), seamless chamber corners, and laminar airflow path minimizing particulate accumulation and cross-contamination risk
• Comprehensive safety architecture: independent overtemperature limiter (adjustable 30–80 °C), dedicated overcurrent/leakage circuit breaker, compressor overload protection, and self-diagnostic alarms for low water level, power failure, sensor fault, and upper/lower limit excursions

Sample Compatibility & Compliance

The ZXJD-A1160 supports standard microbiological consumables including Petri dishes (up to 150 mm), slant tubes, Erlenmeyer flasks (≤1000 mL), and multi-well plates. Its stainless steel electropolished shelving (2 standard, up to 4 optional) accommodates variable-height sample configurations while maintaining airflow integrity. The chamber complies with IEC 61010-1:2010 safety standards for laboratory equipment and meets functional equivalency to ASTM E1980 (Standard Practice for Determining the Performance of Environmental Chambers). While not certified for medical device manufacturing per ISO 13485, its parameter logging, password-protected settings, and power-loss recovery functionality support audit readiness for FDA 21 CFR Part 11–aligned data integrity workflows when paired with optional RS-232 interface and external LIMS integration.

Software & Data Management

Equipped with an LCD display interface offering real-time visualization of setpoints, actual values, elapsed time, and alarm status, the incubator provides local operational transparency without external software dependency. Optional RS-232 serial communication enables bidirectional parameter transfer and remote monitoring via host PC or SCADA systems. An embedded thermal printer (optional add-on) generates time-stamped hardcopy logs of temperature/humidity profiles, cycle completion events, and diagnostic alerts—supporting traceability in QA/QC documentation. All user-defined programs, calibration offsets, and operational history are retained in non-volatile memory with battery-backed clock synchronization, ensuring continuity across scheduled maintenance or facility-wide power outages.

Applications

This incubator serves core functions across regulated and research-intensive life science domains: fungal isolation and identification (e.g., Aspergillus, Penicillium, Candida spp.), antibiotic susceptibility testing under defined moisture gradients, environmental stress response profiling in plant-pathogen interactions, BOD₅ incubation per APHA Standard Methods 5210B, and long-term viability assessment of lyophilized cultures. It is routinely deployed in hospital microbiology labs, biopharmaceutical QC units conducting media fill simulations, agricultural biotech facilities performing seed-borne pathogen screening, and academic mycology departments requiring reproducible sporulation induction environments.
