Overview
The YSEI SHH-1000L Biochemical Incubator is a high-capacity, microprocessor-controlled environmental chamber engineered for precise and stable temperature regulation in life science laboratories. Designed according to GB/T 28851–2012 (General Technical Requirements for Biochemical Incubators), it employs air-jacketed heating combined with compressor-based refrigeration to deliver rapid thermal response and exceptional stability across its operational range of 15–50 °C. Its forced convection system ensures uniform airflow distribution throughout the 1000 L working chamber, minimizing thermal gradients and supporting reproducible cultivation conditions for sensitive biological samples. The incubator is purpose-built for applications requiring long-term, unattended operation—including bacterial and microbial culture, cell maintenance, plant tissue culture, seed germination studies, and biochemical stability testing under controlled thermal environments.
Key Features
- Air-jacketed heating architecture with independent compressor-driven cooling enables simultaneous heating and cooling control, reducing recovery time after door openings and maintaining setpoint integrity during ambient fluctuations.
- High-precision PID temperature control with ±0.1 °C accuracy and ±1 °C fluctuation tolerance—validated at 37 °C—ensures compliance with ISO 13408-2 and USP <1151> requirements for microbiological growth support systems.
- Temperature uniformity of <2.0 °C across the entire chamber volume (measured per IEC 61000-4-2 test protocol at 37 °C) supports GLP-compliant experimental repeatability.
- Dual-stage safety architecture includes independent overtemperature cut-off in the chamber wall, compressor overload protection, and configurable alarm thresholds for deviation events.
- Integrated real-time thermal data logging with optional external thermal printer (paper record output) provides auditable, timestamped traceability aligned with FDA 21 CFR Part 11 Annex 11 expectations for electronic records.
- Low-noise operation (<55 dB[A] at 1 m) and energy-efficient design reduce facility load and enable placement in shared laboratory spaces without acoustic or thermal interference.
Sample Compatibility & Compliance
The SHH-1000L accommodates standard laboratory vessels—including Petri dishes, multi-well plates, flasks (up to 5 L), and tissue culture stacks—within its spacious, corrosion-resistant stainless-steel interior. Removable, adjustable shelves allow flexible configuration for heterogeneous sample loads. The unit complies with GB/T 28851–2012 and meets essential electromagnetic compatibility (EMC) and electrical safety requirements per GB 4793.1–2007 (equivalent to IEC 61010-1). Optional IQ/OQ documentation packages are available to support installation and operational qualification under GMP, GLP, or ISO/IEC 17025-accredited quality systems.
Software & Data Management
A dedicated PC-based monitoring software suite enables centralized management of up to 30 SHH-series incubators via Ethernet or Wi-Fi. Remote access allows real-time parameter adjustment, historical trend visualization (temperature vs. time), and export of CSV-formatted datasets for statistical analysis. Alarm events—including power interruption, temperature excursion, and door-open duration—are transmitted via SMS gateway with customizable recipient lists. Audit trails record all user-initiated changes, including setpoint modifications, calibration adjustments, and alarm acknowledgments—supporting regulatory review under FDA 21 CFR Part 11 and EU Annex 11.
Applications
- Bacterial and fungal culture propagation for clinical diagnostics, food safety testing, and pharmaceutical raw material screening.
- Maintenance of mesophilic cell lines and primary cultures requiring tight thermal control without CO₂ supplementation.
- Plant physiology studies involving seed stratification, callus induction, and photoperiod-independent growth assays.
- Stability assessment of enzymes, vaccines, and biologics under accelerated storage conditions per ICH Q1A(R2).
- Environmental simulation for ecotoxicology experiments where sustained thermal regimes must be maintained over extended durations (≥72 h).
FAQ
What is the maximum ambient temperature at which the SHH-1000L can operate reliably?
The unit is rated for continuous operation in environments between 5 °C and 35 °C ambient temperature, with relative humidity not exceeding 85% RH.
Does the incubator support validation documentation for regulated labs?
Yes—YSEI provides optional Installation Qualification (IQ) and Operational Qualification (OQ) protocols, including test scripts, acceptance criteria, and execution templates compliant with ISO/IEC 17025 and GMP Annex 15.
Can temperature data be exported for regulatory submission?
Yes—CSV exports include timestamps, chamber temperature readings, alarm status flags, and operator identification fields, satisfying ALCOA+ data integrity principles.
Is remote firmware update capability supported?
Firmware updates require local USB connection and authorized service credentials; remote updates are intentionally disabled to preserve system integrity and audit trail continuity.
What is the warranty coverage and post-warranty support model?
Standard warranty is 12 months from commissioning date; extended service contracts and on-site technical support are available globally through YSEI’s authorized partner network.
