Zhongke Aobo SHP-80 Biochemical Incubator

Overview

The Zhongke Aobo SHP-80 Biochemical Incubator is a precision-engineered, forced-air convection incubator designed for stable, long-term temperature-controlled environments in life science laboratories. It operates on the principle of active air circulation via an internal fan system coupled with a high-efficiency, fluorine-free refrigeration module and PTC heating element—enabling precise thermal regulation across its operational range of 5–50 °C. Unlike static incubators, the SHP-80 ensures uniform temperature distribution throughout the chamber (±1 °C) through optimized airflow dynamics and insulated double-wall construction. Its primary application domain includes BOD incubation per ASTM D5210 and ISO 5815, microbial culture (bacteria, fungi, yeasts), cell maintenance under non-CO₂ conditions, environmental water quality testing, seed germination studies, and pharmaceutical stability trials where ambient CO₂ control is not required. The unit complies with general electrical safety standards IEC 61010-1 and is engineered for continuous operation in GLP-compliant academic, clinical, and industrial QC labs.

Key Features

• Stainless steel interior chamber (304 grade) with seamless, rounded corners for enhanced cleanability and corrosion resistance—critical for repeated sterilization cycles and biohazard containment.
• Intelligent microprocessor-based controller featuring PID temperature regulation, programmable timer (up to 999 hours), over-temperature alarm, and automatic cut-off protection to prevent sample loss during power anomalies or sensor failure.
• Energy-efficient, low-noise compressor with R134a-free refrigerant—aligned with Montreal Protocol requirements and reducing environmental impact without compromising cooling capacity.
• Double-layer tempered glass observation window with anti-fog coating enables real-time visual monitoring without thermal disturbance; magnetic door seal ensures >95% insulation integrity and repeatable closure force.
• Multi-layer safety architecture: compressor overheat protection, independent thermostat backup, short-circuit detection, and fault-code diagnostics displayed on the LED interface.
• Optional expansion interfaces include RS-485 for SCADA integration, USB port for data logging to external storage (U-disk), and analog output for external alarm relays or SMS notification modules (via compatible gateway).

Sample Compatibility & Compliance

The SHP-80 accommodates standard laboratory vessels—including Petri dishes, multi-well plates, Erlenmeyer flasks (up to 1 L), and tissue culture bottles—within its 80 L working volume. Shelf configuration supports up to three adjustable stainless steel trays (load capacity: 15 kg per shelf). The unit meets fundamental design criteria referenced in ISO 13408-1 (aseptic processing environments), USP (microbial control), and CLSI M22-A3 (microbiological incubator performance verification). While not certified for GMP manufacturing use out-of-the-box, it is routinely validated by end users for routine QC microbiology per FDA Guidance for Industry: Sterile Drug Products Produced by Aseptic Processing (2004) and EU Annex 1 (2022) when paired with documented IQ/OQ/PQ protocols.

Software & Data Management

The embedded controller stores up to 10 user-defined temperature profiles with time-stamped start/stop events. Real-time temperature logs are exportable via USB in CSV format, supporting traceability requirements under 21 CFR Part 11 (when used with validated third-party software and electronic signature workflows). Optional PC-based software (sold separately) enables remote monitoring, trend analysis, deviation alerts, and automated report generation compliant with ISO/IEC 17025 clause 7.7 (result reporting). Audit trail functionality records all parameter changes, operator IDs (if configured), and system errors—facilitating internal audits and regulatory inspections.

Applications

• Biochemical oxygen demand (BOD₅) determination in wastewater and surface water samples per APHA Standard Methods 5210B.
• Cultivation and preservation of mesophilic bacteria (e.g., E. coli, Salmonella), molds, and yeasts for food safety, clinical diagnostics, and environmental monitoring.
• Plant tissue culture initiation and callus propagation under controlled photoperiod-independent conditions.
• Enzyme activity assays requiring strict thermal consistency over extended durations (e.g., 24–72 h incubations).
• Stability testing of raw materials and finished products under ICH Q1A(R2) intermediate storage conditions (30 °C ± 2 °C / 65% RH ± 5% RH, when paired with optional humidity module).

FAQ

Does the SHP-80 support humidity control?

No—the SHP-80 is a dry-air incubator. Humidity control requires the optional SHP-H series variant equipped with ultrasonic humidification and condensation recovery.

Is calibration certificate included with shipment?

A factory calibration report (traceable to NIM, China) is provided; full ISO/IEC 17025-accredited calibration must be arranged separately via authorized service partners.

Can the unit operate continuously at 5 °C in ambient temperatures above 35 °C?

Yes—its refrigeration system is rated for sustained operation at minimum setpoint under ≤40 °C ambient, provided adequate ventilation clearance (≥10 cm on all sides) is maintained.

What is the maximum allowable load weight inside the chamber?

Total payload must not exceed 45 kg, distributed evenly across shelves to preserve airflow symmetry and thermal uniformity.

Is the controller firmware upgradeable in the field?

Firmware updates are supported via USB using manufacturer-provided tools and require authorized technician access; version history and release notes are available upon request from technical support.
