Overview
The YSEI SHH-L Series Biochemical Incubator is a precision-engineered, air-jacketed temperature-controlled chamber designed for stable, long-term cultivation and storage of bacteria, fungi, yeasts, mammalian cell lines, and plant tissues under tightly regulated thermal conditions. Built upon the technical foundation of GB/T 28851–2012 (General Technical Requirements for Biochemical Incubators), this series integrates compressor-based refrigeration with forced-air convection to deliver uniform thermal distribution across the entire working chamber — critical for reproducible microbiological assays, seed germination studies, enzymatic activity profiling, and low-temperature stability testing. Its operational range (4–50 °C) supports both mesophilic culture protocols and cold-adapted organism maintenance, while the ±0.1 °C temperature accuracy and ±0.5 °C fluctuation tolerance meet stringent requirements for GLP-compliant environmental simulation and QC release testing.
Key Features
- Air-jacketed heating architecture ensures rapid thermal response and minimal internal gradient formation during setpoint transitions.
- Compressor-driven cooling system enables precise sub-ambient control down to 4 °C with consistent condensation management and low energy consumption per cycle.
- Forced convection via adjustable-speed centrifugal fans guarantees uniform temperature distribution (±2.0 °C at 37 °C), validated per ISO 15272:2015 guidelines for incubator performance verification.
- Dual independent safety circuits: dedicated over-temperature cutoff in the chamber and separate compressor overload protection prevent hardware failure and sample loss.
- Integrated thermal printer provides real-time, tamper-evident paper records — configurable print intervals support 21 CFR Part 11–compliant audit trails when paired with timestamped data logging.
- Remote SMS alarm module delivers immediate notification for power interruption, temperature deviation (>±1.0 °C from setpoint), or sensor fault — scalable to centralized monitoring of up to 30 units via single IP gateway.
Sample Compatibility & Compliance
The SHH-L series accommodates standard laboratory vessels including Petri dishes, multi-well plates, Erlenmeyer flasks, roller bottles, and tissue culture stacks. Its stainless-steel interior (electropolished AISI 304), rounded corners, and seamless welds minimize microbial harborage and simplify cleaning validation per ISO 14644–1 Class 7 cleanroom maintenance protocols. All models are CE-marked and conform to IEC 61010–1:2010 for electrical safety in laboratory equipment. Documentation packages include IQ/OQ protocols aligned with ASTM E2500–13 and EU Annex 15 requirements, supporting regulatory submissions for pharmaceutical, biotech, and academic GxP environments.
Software & Data Management
A web-enabled embedded controller supports local touchscreen operation and remote access via Ethernet or Wi-Fi. The system logs temperature readings at user-defined intervals (1 sec–60 min) with automatic CSV export to network drives or USB media. Data integrity is preserved through cyclic redundancy check (CRC) validation, encrypted storage, and time-stamped event markers for all parameter changes. Audit trail functionality meets FDA 21 CFR Part 11 criteria, including electronic signatures, role-based access control (admin/operator modes), and immutable log archiving. Optional cloud integration enables secure offsite backup and cross-site comparative analysis using RESTful API endpoints.
Applications
- Bacterial growth kinetics and antibiotic susceptibility testing (AST) under controlled thermal stress.
- Mycelial expansion and spore viability assessment in fungal bioprospecting workflows.
- Plant tissue culture initiation, callus induction, and photoperiod-independent germination trials.
- Long-term stability studies for diagnostic reagents, vaccines, and lyophilized biologics (ICH Q5C).
- Environmental simulation for ecotoxicology assays requiring precise thermal ramping profiles.
- QC/QA release testing of raw materials in food safety and cosmetic ingredient manufacturing (ISO 22000, ISO 22716).
FAQ
What is the maximum number of SHH-L units that can be managed simultaneously via the central monitoring software?
Up to 30 units may be configured within a single LAN subnet using the native YSEI Network Manager application.
Does the incubator support humidity control?
No — the SHH-L series is a temperature-only incubator; relative humidity is not actively regulated or monitored.
Is the thermal printer compatible with LIMS integration?
Yes — printed reports include machine-readable QR codes linking to full digital datasets stored on the onboard SD card or network share.
Can the device operate continuously at 4 °C for extended periods?
Yes — the compressor system is rated for continuous duty at minimum setpoint, with automatic defrost cycles preventing ice accumulation in the evaporator coil.
What validation documentation is provided for GMP environments?
Factory-issued IQ/OQ templates, calibration certificates traceable to NIM (China National Institute of Metrology), and test reports per GB/T 28851–2012 are included with each shipment.
