Zhicheng ZXSD-A1270 Ten-Stage Programmable Biochemical Incubator

Overview

The Zhicheng ZXSD-A1270 Ten-Stage Programmable Biochemical Incubator is an engineered platform for precise, reproducible, and traceable temperature-controlled environmental simulation in life science laboratories. Designed for applications requiring dynamic thermal profiles—such as microbial growth kinetics, enzyme activity assays, cell line adaptation, and stability testing—the incubator employs fuzzy logic control architecture to minimize overshoot and stabilize setpoints rapidly under variable load conditions. Its air-cooled, R134a-based refrigeration system operates in frost-free mode with modulated compressor output, enabling seamless transitions between heating and cooling phases across the full operational range of 4–65 °C. The chamber’s forced convection airflow, optimized via a low-turbulence duct geometry and rear-mounted centrifugal blower, ensures uniform thermal distribution (≤±1 °C at 37 °C) and minimizes boundary-layer stagnation around sensitive biological samples.

Key Features

• Ten-segment programmable controller supporting up to 18 discrete thermal steps, with individual step durations configurable from 1 to 999 minutes—ideal for simulating diurnal cycles, fermentation ramps, or multi-phase incubation protocols.
• Fuzzy logic temperature regulation with 0.1 °C resolution and real-time adaptive compensation for ambient fluctuations (operational within 5–35 °C ambient).
• Dual independent safety layers: adjustable over-temperature cutoff (30–80 °C), plus fixed overheat prevention device—both electrically isolated from the main control circuit per IEC 61010-1 requirements.
• Comprehensive self-diagnostic suite: automatic detection and visual/audible alerts for power interruption, Pt100 sensor failure, and upper/lower temperature excursions.
• Mirror-finish 304 stainless steel interior with electropolished shelving and seamless welded corners—facilitating ISO 14644-compliant cleaning validation and minimizing microbial retention.
• Double-glazed observation door with low-emissivity inner thermal glass reduces radiant heat loss while maintaining optical clarity for non-invasive sample monitoring.
• Φ50 mm pass-through port fitted with silicone gasket enables integration with external sensors, gas supply lines, or data loggers without compromising chamber integrity.

Sample Compatibility & Compliance

The ZXSD-A1270 accommodates standard microbiological vessels—including Petri dishes, Erlenmeyer flasks (up to 2 L), roller bottles, and multi-well plates—on two factory-installed electro-polished stainless steel shelves (expandable to four). Its chamber geometry (600 × 600 × 750 mm) supports staggered shelving configurations to optimize airflow penetration. The unit complies with GB/T 17249.1–2021 (Chinese national standard for incubators), and its electrical safety design conforms to IEC 61010-1:2010 (Measurement, Control, and Laboratory Equipment). When equipped with RS-232 interface and optional embedded thermal printer, it supports audit-ready documentation per GLP and GMP Annex 11 principles—including timestamped event logging, parameter change tracking, and calibration history archiving.

Software & Data Management

While the ZXSD-A1270 operates via standalone front-panel LCD interface, its RS-232 serial port enables bidirectional communication with third-party laboratory information management systems (LIMS) or custom SCADA platforms using ASCII protocol. All programmed sequences, real-time temperature readings, alarm events, and runtime statistics are exportable as CSV-formatted logs. Optional embedded thermal printer provides hard-copy records of temperature traces and operational status—critical for FDA 21 CFR Part 11–aligned environments where handwritten logs are insufficient. Parameter memory retains all user-defined settings through power cycling, and password-protected configuration mode prevents unauthorized modification of critical safety thresholds.

Applications

• Microbial culture maintenance and growth curve analysis under time-varying thermal regimes (e.g., mesophilic-to-thermophilic transition studies).
• Biochemical assay development requiring precise thermal ramping—such as protein denaturation profiling or polymerase chain reaction (PCR) reagent stability assessment.
• Pharmaceutical stability testing per ICH Q1A(R2) guidelines, including intermediate condition simulations (e.g., 30 °C/65% RH equivalents via controlled dry-heat exposure).
• Agricultural seed germination trials with photoperiod-independent thermal programming.
• Environmental simulation for ecotoxicology studies involving temperature-dependent metabolic rate modeling.
• Long-term storage of temperature-sensitive reagents (e.g., restriction enzymes, antibodies) under validated isothermal conditions.

FAQ

What is the maximum number of programmable temperature segments supported?
The incubator supports 10 total segments: Segment “0” functions as a pre-conditioning or standby stage, while Segments 1–9 constitute fully editable control steps—each capable of independent temperature setpoint, duration, and ramp rate definition.
Does the unit meet international electromagnetic compatibility (EMC) standards?
Yes—electromagnetic emissions and immunity performance comply with EN 61326-1:2013 for laboratory equipment, verified during factory type testing.
Can the internal temperature sensor be calibrated in situ?
Yes—the LCD interface includes a dedicated temperature display offset function (±5.0 °C range in 0.1 °C increments), allowing field adjustment against a NIST-traceable reference probe.
Is remote monitoring possible without the optional printer?
Yes—RS-232 connectivity enables continuous streaming of live temperature data and alarm status to a host PC or networked data acquisition system using standard terminal emulation software.
What is the warranty coverage and service support structure?
Zhicheng provides a 24-month limited warranty covering parts and labor for manufacturing defects, with technical support available via email and documented troubleshooting guides compliant with ISO/IEC 17025 calibration traceability requirements.
