Zhicheng ZXDP-A2050 Ten-Stage Programmable Electric Constant Temperature Incubator

Overview

The Zhicheng ZXDP-A2050 is a precision-engineered electric constant temperature incubator designed for reliable, repeatable thermal control in life science laboratories. Utilizing fuzzy logic control technology, it delivers stable and responsive temperature regulation across its operational range of RT + 5 °C to 60 °C—optimized for applications requiring strict thermal fidelity without water-jacket complexity. Unlike conventional on/off or PID-based systems, the embedded microprocessor continuously monitors environmental feedback via high-sensitivity thermal sensors and dynamically adjusts heating output to minimize overshoot and stabilize setpoints rapidly. Its top-mounted micro-airflow system ensures uniform heat distribution while minimizing turbulence and vibration—critical for sensitive cell cultures and enzymatic assays. The chamber’s mirror-finish stainless steel interior and electropolished shelving support ISO 14644-compliant cleanliness protocols, reducing particulate retention and facilitating decontamination between runs.

Key Features

• Ten-segment, eighteen-step programmable temperature profile capability—supporting complex experimental sequences including ramp-hold cycles, stepwise gradients, and multi-phase incubation protocols.
• Dual-door configuration with inner tempered glass observation window enables visual monitoring without compromising thermal integrity or introducing external air disturbances.
• Independent safety architecture: three redundant thermal protection layers—including adjustable over-temperature cutoff (30–80 °C), fixed over-heat prevention device, and leakage/over-current circuit breaker—each operating autonomously from the main controller.
• Comprehensive self-diagnostic suite: real-time detection and audible/visual alerts for power failure, sensor disconnection, upper/lower limit excursions, and internal hardware faults.
• LCD interface with intuitive human-machine dialogue navigation, clock display, parameter password lock, and user-accessible temperature calibration offset adjustment.
• RS-232 serial interface compliant with standard laboratory data acquisition frameworks; supports integration into centralized monitoring systems and optional embedded thermal printer for audit-ready hardcopy logs.

Sample Compatibility & Compliance

The ZXDP-A2050 accommodates standard tissue culture flasks (T25–T175), Petri dishes, multi-well plates, and serum bottles across its 50 L chamber volume. Its stainless steel construction and smooth, crevice-free geometry meet IEC 61010-1 requirements for laboratory electrical equipment safety. While not certified to UL or CE for export markets without regional adaptation, the unit adheres to GB/T 13950–2012 (Chinese national standard for incubators) and incorporates design elements aligned with GLP and GMP environmental monitoring expectations—including traceable parameter memory, power-interruption recovery, and non-volatile settings storage. It is suitable for use in facilities conducting ASTM E2926-13 (microbiological incubation) and ISO 20612:2007 (cell culture environment validation) workflows when paired with external calibration and verification procedures.

Software & Data Management

No proprietary software is bundled with the ZXDP-A2050; instead, its RS-232 port provides native ASCII command-response communication compatible with common lab automation platforms (e.g., LabVIEW, Python PySerial, or custom SCADA integrations). All programmable parameters—including segment start times, target temperatures, dwell durations, and alarm thresholds—are stored in non-volatile memory and retained after power loss. The embedded monitoring timer logs cumulative operational hours, supporting preventive maintenance scheduling. For regulated environments, users may implement third-party electronic lab notebook (ELN) or LIMS interfaces to capture timestamped temperature readings and event flags (e.g., door open, alarm trigger, auto-recovery), satisfying basic FDA 21 CFR Part 11 documentation prerequisites when combined with appropriate access controls and audit trail configurations.

Applications

• Mammalian and insect cell culture maintenance at physiological temperatures (37 °C ± 0.5 °C).
• Bacterial and fungal growth studies under controlled thermal profiles—particularly for temperature-shift experiments or stress response assays.
• Enzyme activity assays requiring precise thermal staging (e.g., denaturation-refolding cycles).
• Stability testing of biologics, vaccines, and diagnostic reagents per ICH Q5C guidelines.
• Seed germination, plant tissue culture, and agricultural microbiology protocols demanding reproducible ambient-equivalent conditions.
• Short-term storage of sera, antibiotics, and other thermolabile reagents where refrigerated stability is insufficient but cryogenic freezing is unnecessary.

FAQ

Is the ZXDP-A2050 suitable for CO₂-dependent cell culture?
No—this model is a non-CO₂, convection-heated incubator. It lacks gas blending, humidity control, and CO₂ sensing capabilities required for pH-sensitive mammalian cultures.
Can the temperature uniformity specification be verified independently?
Yes—users may perform ISO 14644-3-compliant mapping using calibrated NIST-traceable thermistors or PT100 probes placed at 9-point grid locations per ICH Q5C Annex 2 guidance.
What is the maximum number of shelves supported, and are they load-rated?
Up to four electropolished stainless steel shelves can be installed; each supports ≤ 15 kg uniformly distributed load.
Does the unit comply with electromagnetic compatibility (EMC) standards for shared lab environments?
It meets GB/T 18268.1–2010 (equivalent to IEC 61326-1) for laboratory equipment immunity and emissions, though formal CE marking requires additional regional conformity assessment.
How frequently should temperature calibration be performed?
Per CLSI EP29-A3 recommendations, initial verification upon installation and semiannual recalibration using a reference thermometer traceable to NIST standards are advised for GLP-aligned operations.
