Zhicheng ZXJP-A1150 Ten-Stage Programmable Mold Incubator

Overview

The Zhicheng ZXJP-A1150 Ten-Stage Programmable Mold Incubator is a precision-engineered environmental chamber designed specifically for controlled fungal cultivation, microbial growth studies, and long-term stability testing under regulated temperature and relative humidity conditions. Built upon a robust stainless steel architecture with electropolished interior surfaces and double-glazed insulated doors, it delivers stable, reproducible microclimates essential for ISO 17025-accredited laboratories and GLP-compliant research workflows. Its core operating principle integrates fuzzy logic control algorithms with high-fidelity dual-parameter sensing—simultaneously monitoring and modulating both air temperature and RH in real time—to maintain tight environmental tolerances across extended operational cycles. Unlike basic static incubators, the ZXJP-A1150 supports dynamic, multi-segment environmental profiling, enabling researchers to simulate natural diurnal cycles, stress-response protocols, or staged incubation regimens required in mycological taxonomy, spore germination kinetics, and antifungal efficacy screening.

Key Features

• Fuzzy logic-based dual-loop control system ensures coordinated regulation of temperature (0–65 °C) and humidity (40–95 %RH) with resolution of 0.1 °C and 0.1 %RH respectively
• 10-segment, 18-step programmable controller supports complex ramp-hold-cycle sequences; each segment allows independent setpoint definition and dwell time (1–999 minutes)
• Frost-free refrigeration system using R134a refrigerant with variable-speed compressor control, eliminating manual defrosting and ensuring uninterrupted operation
• Secondary reservoir humidification architecture with automatic water replenishment—no manual refilling required during multi-day runs
• Forced-air circulation via high-efficiency turbo fan and optimized internal airflow ducting achieves ≤±1 °C temperature uniformity at 37 °C and ≤±6 %RH humidity uniformity across the 150 L working volume
• Dual independent safety layers: adjustable overtemperature limiter (30–80 °C), fixed overheat cutout, earth-leakage circuit breaker, and refrigeration overload protection
• Comprehensive self-diagnostic suite including low-water level detection, sensor failure alert, power interruption logging, and upper/lower deviation alarms
• LCD interface with real-time parameter display, clock synchronization, parameter password lock, and calibration offset adjustment capability
• Structural integrity enhanced by mirror-finish 304 stainless steel interior, electropolished shelving (2 standard, upgradable to 4), and tempered glass inner door with low-emissivity coating

Sample Compatibility & Compliance

The ZXJP-A1150 accommodates standard microbiological formats—including Petri dishes (up to 150 mm), test tubes, multiwell plates, and culture flasks—within its geometrically optimized chamber. Its smooth-welded, crevice-free interior minimizes particulate accumulation and facilitates validated cleaning protocols per ISO 14644 cleanroom standards. The unit complies with IEC 61010-1 for laboratory equipment safety and meets electromagnetic compatibility requirements per EN 61326-1. While not certified to FDA 21 CFR Part 11 out-of-the-box, its RS-232 interface enables integration with compliant LIMS or ELN systems supporting audit-trail-enabled data capture. For applications requiring regulatory traceability (e.g., pharmaceutical stability testing per ICH Q1), optional embedded thermal printing provides hard-copy record generation aligned with ALCOA+ principles.

Software & Data Management

Local operation is managed through an intuitive front-panel LCD interface with non-volatile memory preserving all user-defined parameters—including program sequences, calibration offsets, and access passwords—even after power loss. The built-in RS-232 port supports ASCII protocol communication for remote monitoring, parameter upload/download, and real-time data streaming to host PCs running custom scripts or third-party SCADA platforms. When equipped with the optional embedded thermal printer, the incubator generates timestamped printouts of current setpoints, actual readings, alarm events, and elapsed cycle durations—providing immediate physical documentation suitable for lab notebooks and internal QA review. All safety-triggered events are logged with timestamps and retained in nonvolatile memory for post-event forensic analysis.

Applications

• Fungal isolation, identification, and strain preservation in clinical and environmental microbiology labs
• BOD₅ and respirometric assays requiring stable 20–25 °C and ≥90 %RH conditions per APHA Standard Methods
• Plant pathology studies involving pathogen inoculation and lesion development under controlled moisture gradients
• Stability assessment of biologics, vaccines, and diagnostic reagents per ICH Q5C guidelines
• Validation of sterilization process indicators (e.g., biological indicators containing Geobacillus stearothermophilus spores) under sub-lethal incubation profiles
• Environmental simulation for material testing—including mold resistance evaluation of construction materials per ASTM D3273
• Long-term seed viability and germination trials under stratification-mimicking temperature/humidity cycles

FAQ

What is the maximum allowable ambient temperature for continuous operation?
The incubator is rated for uninterrupted use within ambient temperatures of 5–35 °C. Operation above 35 °C may compromise humidity control stability and refrigeration efficiency.
Can the incubator maintain humidity below 40 %RH?
No—the minimum specified RH range is 40 %RH. For desiccating or low-humidity applications, a dedicated dry box or low-RH incubator is recommended.
Is the RS-232 interface compatible with modern Windows/macOS systems?
Yes, using a standard USB-to-serial adapter and terminal emulation software (e.g., Tera Term, PuTTY) or custom Python/Node-RED scripts with appropriate baud rate configuration (default: 9600, 8-N-1).
How often does the secondary water reservoir require maintenance?
Under typical usage (80 %RH, 25 °C), the reservoir supports ≥72 hours of unattended operation; visual inspection is advised weekly, and distilled water replenishment is required only when the low-water alarm activates.
Does the unit support validation documentation packages (IQ/OQ/PQ)?
Zhicheng provides factory calibration certificates and electrical safety test reports. Full qualification documentation requires site-specific execution by qualified personnel using NIST-traceable probes and standardized protocols per ISO/IEC 17025.
