Zhicheng ZXJP-A1430 Ten-Stage Programmable Mold Incubator

Overview

The Zhicheng ZXJP-A1430 Ten-Stage Programmable Mold Incubator is a precision-engineered environmental chamber designed for controlled fungal cultivation, microbial growth studies, and long-term biological sample maintenance under tightly regulated temperature and humidity conditions. Built upon fuzzy logic control architecture, it delivers high reproducibility in maintaining setpoints across extended operational cycles—critical for applications requiring strict adherence to standardized incubation protocols (e.g., ISO 8573-1, ASTM D3273 for mold resistance testing, or USP / microbiological enumeration). Its 430 L working volume, combined with a dual-layer insulated door system and mirror-polished stainless-steel interior, ensures thermal and hygric stability while minimizing contamination risk and facilitating GMP-compliant cleaning validation.

Key Features

• Ten-stage, eighteen-step programmable control sequence enabling complex multi-phase environmental profiles—including ramp-and-soak temperature/humidity transitions, cyclic stepping, and staircase scheduling for sequential physiological stress assays.
• Integrated high-response capacitive humidity sensor and platinum RTD temperature sensor with 0.1 °C / 0.1 %RH resolution and ≤±0.5 °C / ≤±2 %RH stability performance at nominal operating points.
• Frost-free refrigeration system using R134a refrigerant with variable-speed compressor modulation, eliminating manual defrost cycles and ensuring uninterrupted operation during prolonged experiments.
• Secondary water reservoir with automatic replenishment mechanism—eliminates manual refilling and supports continuous humidity generation for up to 72 hours under typical 60–80 %RH setpoints.
• Dual independent safety architecture: hardware-based overtemperature cutoff (adjustable 30–80 °C), dedicated overcurrent/leakage circuit breaker, and microprocessor-driven self-diagnostic monitoring (low-water, sensor failure, power interruption, upper/lower limit deviation).
• Ergonomic air distribution design featuring a high-efficiency turbine blower and optimized internal duct geometry—achieving ≤±1 °C temperature uniformity and ≤±6 %RH humidity uniformity at 37 °C per IEC 61000-4-2 compliance test methodology.

Sample Compatibility & Compliance

The ZXJP-A1430 accommodates standard Petri dishes (up to 150 mm), multi-well plates, culture flasks (T75/T175), and agar slants without spatial interference. Its stainless-steel electropolished shelves (2 standard, expandable to 4) and seamless chamber geometry support ISO 14644-1 Class 5 cleanroom-compatible handling practices. The unit meets electromagnetic compatibility requirements per EN 61326-1 and conforms to electrical safety standards per IEC 61010-1. Optional RS-232 interface enables integration into laboratory information management systems (LIMS) and supports audit-trail-capable data logging aligned with FDA 21 CFR Part 11 principles when paired with validated third-party software.

Software & Data Management

Equipped with an embedded LCD interface supporting real-time parameter display, clock synchronization, and password-protected configuration access. All user-defined programs—including time-stamped start/stop commands, step duration (1–999 minutes), and ramp rates—are retained in non-volatile memory with power-failure recovery. An optional built-in thermal printer provides hard-copy output of current setpoints, actual readings, and alarm events—satisfying GLP documentation requirements for traceability. Remote monitoring and parameter adjustment are achievable via ASCII protocol over RS-232, allowing scripted automation through Python or LabVIEW environments.

Applications

This incubator serves as a core platform for mycological research (e.g., Aspergillus, Penicillium, and Cladosporium strain propagation), BOD₅ and biodegradation assays, pharmaceutical stability testing per ICH Q1A(R2), seed germination trials, plant tissue culture acclimatization, and environmental microbiology (e.g., wastewater biofilm development, airborne spore viability assessment). Its precise humidity control makes it suitable for ASTM G21 antimicrobial efficacy evaluation and ISO 16000-10 indoor air quality simulation studies.

FAQ

What is the maximum allowable ambient temperature for stable operation?
The unit is rated for continuous use within an ambient range of 5–35 °C; operation above 35 °C may compromise humidity regulation accuracy and compressor duty cycle.
Can the incubator maintain humidity below 40% RH?
No—the minimum programmable humidity setpoint is 40% RH, as lower levels require desiccant-based or purge-gas systems not integrated into this model.
Is calibration certificate included with shipment?
Factory calibration verification is performed pre-shipment; NIST-traceable calibration certificates are available upon request with additional lead time and fee.
How many data points can be logged internally without external storage?
The onboard memory retains up to 10,000 timestamped records (temperature/humidity/time) before overwrite; continuous export via RS-232 is recommended for long-term studies.
Does the unit comply with GLP or GMP requirements?
While the hardware supports GLP/GMP workflows (audit trail, password protection, parameter lockout), formal compliance depends on site-specific validation protocols including IQ/OQ/PQ execution and documented change control procedures.
