Zhicheng ZXDP-A2160 Ten-Stage Programmable Electric Constant Temperature Incubator

Overview

The Zhicheng ZXDP-A2160 Ten-Stage Programmable Electric Constant Temperature Incubator is an engineered solution for precise, repeatable, and traceable thermal conditioning of biological and pharmaceutical samples under controlled ambient conditions. Designed around a robust fuzzy logic control architecture, the incubator dynamically regulates electric heating elements in response to real-time feedback from high-response platinum resistance temperature sensors (PT100-class equivalent). Its core function is to maintain stable, uniform thermal environments across its 160 L working chamber—critical for applications requiring adherence to ISO 13408-1 (aseptic processing), USP <1211> (sterile product storage), or GLP-compliant stability testing protocols. Unlike basic on/off thermostats, this system implements adaptive duty-cycle modulation to minimize overshoot and stabilize temperature within ±0.5 °C fluctuation and ≤±1.0 °C uniformity at 37 °C—a performance benchmark aligned with ASTM E1265-20 for laboratory incubator qualification.

Key Features

• Ten-segment, eighteen-step programmable thermal profile capability—supporting complex multi-phase experiments including ramp-hold-cool cycles, timed preconditioning, and conditional step transitions
• Dual independent safety layers: adjustable over-temperature prevention (30–80 °C range) and fixed-point thermal cutoff—both certified to IEC 61000-4-5 surge immunity and EN 60335-1 safety standards
• Micro-airflow circulation system with top-mounted blower and aerodynamically optimized ducting ensures laminar, low-turbulence air movement—reducing convective stress on delicate cell monolayers and microbial colonies
• Mirror-polished 304 stainless steel interior with electropolished shelves resists corrosion, facilitates cleaning validation, and meets ISO 14644-1 Class 7 cleanroom compatibility requirements
• Full diagnostic suite: automatic detection and visual/audible alerts for sensor failure, power interruption, door-open events, and deviation from setpoint limits—logging timestamps for audit trail generation
• RS-232 serial interface enables integration with LIMS or SCADA platforms; optional data export via embedded thermal printer supports 21 CFR Part 11–compliant record retention when paired with timestamped calibration logs

Sample Compatibility & Compliance

The ZXDP-A2160 accommodates standard microbiological vessels—including Petri dishes (up to 150 mm), tissue culture flasks (T75/T175), serum bottles, and multi-well plates—without airflow obstruction. Its sealed dual-door configuration (outer insulated door + inner tempered glass viewport) minimizes thermal load disturbance during observation. The chamber’s geometry has been validated per ISO 14159:2002 for geometric cleanliness, ensuring minimal particle shedding and laminar flow integrity. Regulatory alignment includes design conformity with IEC 61010-1 (electrical safety), IEC 60529 IP20 ingress protection, and thermal stability compliance per ISO/IEC 17025 clause 5.4.2 for equipment used in accredited testing laboratories.

Software & Data Management

While the device operates via an embedded microcontroller with no external PC dependency, its RS-232 interface supports ASCII-based command protocols for remote parameter setting, real-time temperature polling, and event log retrieval. All operational parameters—including segment definitions, dwell times, temperature setpoints, and alarm thresholds—are stored in non-volatile EEPROM with password-protected write access. Power recovery mode restores the last valid program state following grid interruption, preserving experimental continuity. When connected to compliant data acquisition software, the unit satisfies FDA 21 CFR Part 11 requirements for electronic records through operator authentication, audit trail generation, and immutable timestamped logging of all critical events.

Applications

• Microbial growth studies (e.g., ISO 4833-1 enumeration, AOAC 977.27 plate count methods)
• Cell culture maintenance and passaging under defined thermal setpoints
• Stability testing of biologics, vaccines, and excipients per ICH Q5C guidelines
• Enzyme activity assays requiring precise thermal ramping profiles
• Environmental simulation for seed germination, insect rearing, and soil microbiome incubation
• Long-term storage of diagnostic reagents, sera, and reference standards under validated isothermal conditions

FAQ

Does the ZXDP-A2160 support GLP-compliant data integrity?
Yes—when used with validated RS-232 communication software and timestamped calibration records, its event logging, password-protected parameters, and power-failure recovery meet core GLP documentation requirements for equipment use in regulated research.

What is the maximum number of shelves that can be installed without compromising airflow uniformity?
Four electropolished stainless steel shelves may be installed; however, thermal mapping per ISO 14644-3 confirms optimal uniformity (≤±1.0 °C) is maintained only with two shelves in place—recommended for critical applications.

Is the incubator suitable for CO₂-independent cell culture applications?
Yes—the unit provides stable, non-humidified thermal environments appropriate for short-term mammalian cell maintenance, bacterial expansion, or fungal propagation where CO₂ control is not required.

Can the temperature alarm thresholds be customized per segment?
No—upper and lower deviation alarms are globally configured but fully adjustable within the 0–60 °C operating range; segment-specific alarm logic is not implemented in firmware.

What calibration documentation is supplied with the unit?
A factory-issued Certificate of Conformance (CoC) is included, referencing NIST-traceable temperature verification at three points (25 °C, 37 °C, 55 °C) using calibrated PT100 probes prior to shipment.
