Zhicheng ZXSD-1270 Advanced Automated Biochemical Incubator

Overview

The Zhicheng ZXSD-1270 Advanced Automated Biochemical Incubator is a precision-engineered environmental chamber designed for stable, reproducible cultivation of microorganisms, cell lines, and biological samples under tightly controlled thermal conditions. Built upon a robust forced-convection architecture, the unit employs high-response thermistors coupled with an embedded environmental scanning microprocessor to achieve real-time thermal feedback and adaptive control. Its operating range spans 4 °C to 65 °C—encompassing standard mesophilic, psychrophilic, and thermotolerant incubation protocols—with resolution of 0.1 °C and guaranteed stability of ≤ ±0.5 °C (fluctuation) and ≤ ±1.0 °C (uniformity across the 270 L working volume). The chamber’s thermally insulated dual-door system—featuring an outer insulated panel and an inner tempered glass viewport—minimizes heat loss while enabling continuous visual monitoring without compromising internal environment integrity.

Key Features

• Microprocessor-based PID temperature control with environmental scanning algorithm for dynamic compensation against ambient drift and door-opening events.
• Acoustic-optical overtemperature alarm with automatic heater cutoff upon detection of thermal runaway or sensor fault.
• Optimized laminar airflow duct design ensuring uniform air distribution and minimizing thermal stratification—validated per ISO 14644-1 Class 8 cleanroom-compatible cavity geometry.
• Electropolished stainless-steel interior surfaces and mirror-finish stainless steel shelving (2 standard, up to 4 configurable) for corrosion resistance, ease of decontamination, and compliance with GLP cleaning validation requirements.
• Intelligent power recovery function: automatically resumes pre-interruption setpoints and timer countdown following AC power restoration—critical for unattended overnight or multi-day assays.
• Non-volatile parameter memory retains user-defined configurations (setpoint, timer, display mode) across power cycles—eliminating redundant reconfiguration in shared-lab environments.
• Programmable digital timer (1 minute to 99 hours 59 minutes) with independent start/pause controls and elapsed-time tracking for protocol adherence and audit trail generation.
• LED display interface presenting both setpoint and real-time chamber temperature simultaneously—designed for legibility under standard laboratory lighting conditions (≥200 lux).

Sample Compatibility & Compliance

The ZXSD-1270 accommodates a broad spectrum of biological containment formats—including Petri dishes, multi-well plates, culture flasks (T25 to T225), roller bottles, and sterile sample containers—within its 600 × 600 × 750 mm internal cavity. Its stainless-steel construction and smooth, crevice-free geometry support routine sanitization using ethanol, hydrogen peroxide vapor (HPV), or validated liquid disinfectants per ISO 15223-1 labeling standards. While not certified as a biosafety cabinet, the unit meets IEC 61010-1 safety requirements for laboratory equipment and complies with electromagnetic compatibility (EMC) directives (IEC 61326-1). Its thermal performance characteristics align with ASTM E171 and ISO 8573-1 Annex B recommendations for incubator qualification in QC microbiology workflows.

Software & Data Management

The ZXSD-1270 operates as a standalone, firmware-controlled instrument with no proprietary software dependency. All operational parameters—including temperature logs, alarm timestamps, and power interruption records—are stored locally in non-volatile memory with timestamped entries (YYYY-MM-DD HH:MM:SS). Optional RS-232 or USB-to-serial interface modules (sold separately) enable integration with laboratory information management systems (LIMS) or data acquisition platforms for automated CSV export. Audit trails comply with FDA 21 CFR Part 11 principles when paired with validated third-party data capture software supporting electronic signatures and user access controls. No cloud connectivity or remote firmware updates are implemented—ensuring data sovereignty and network isolation per institutional IT security policies.

Applications

This incubator serves core functions across regulated and research-intensive life science domains: bacterial and fungal strain maintenance per CLSI M22-A3 guidelines; aerobic/anaerobic microbial growth studies in pharmaceutical stability testing (ICH Q5C); enzyme activity profiling at defined thermal setpoints; seed germination and plant tissue culture under controlled photoperiod-agnostic conditions; and environmental isolate enrichment in ecological microbiology. Its 4 °C lower limit supports cold-adapted organism propagation, while the 65 °C upper bound permits accelerated shelf-life modeling and thermal inactivation validation. Routine use is documented in ISO/IEC 17025-accredited labs for media sterility assurance, endotoxin testing incubation, and bioburden enumeration (USP , EP 2.6.12).

FAQ

Does the ZXSD-1270 support CO₂ or humidity control?
No. This is a temperature-only incubator. It does not integrate gas regulation or humidification subsystems.

Can additional shelves be installed without tools?
Yes. The electropolished stainless-steel shelf support rails accept up to four shelves; installation requires only manual alignment and gravity locking—no fasteners or calibration needed.

Is the unit suitable for GMP manufacturing environments?
It may be deployed in GMP settings as a secondary support device (e.g., for media storage or non-critical incubation), provided it undergoes IQ/OQ/PQ validation per Annex 15 and maintains calibrated thermistor traceability to NIST standards.

What is the recommended calibration interval?
Annual verification using a NIST-traceable reference thermometer (Class A, ±0.1 °C) is advised. Calibration points should include 25 °C, 37 °C, and 55 °C—covering typical microbiological, mammalian, and thermophile operating ranges.

How is door-opening impact mitigated during operation?
The environmental scanning microprocessor detects rapid temperature deviation and initiates predictive heating compensation within 15 seconds of door closure, restoring setpoint stability in ≤3 minutes (tested at 25 °C ambient, single 10-second door opening).
