Overview
The BOXUN BPX-272 Electrically Heated Constant-Temperature Incubator is a precision-engineered dry incubation system designed for stable, reproducible thermal environments in life science laboratories. It operates on resistive heating and forced-air convection principles, delivering uniform temperature distribution without humidity control—making it ideal for applications requiring sterile, low-moisture conditions such as bacterial culture propagation, enzyme activity assays, cell line maintenance (non-CO₂-dependent), and pharmaceutical stability testing. Its robust architecture features a double-walled insulated chamber with high-efficiency mineral wool insulation and nano-composite door sealing, minimizing thermal leakage and enhancing energy efficiency. The unit complies with general laboratory equipment safety standards (IEC 61010-1) and supports GLP-aligned operational traceability when integrated with optional data logging or printer modules.
Key Features
- Microprocessor-based PID temperature controller with LCD interface displaying real-time setpoint, actual temperature, timer status, and system alerts
- Three-tier adjustable stainless-steel shelving system with smooth slide rails and load capacity up to 15 kg per shelf
- Optimized airflow design using a brushless DC motor and multi-directional air ducts ensures ±0.5°C uniformity across the full 243 L chamber volume at 37°C
- Programmable operation with up to 100 cycles across 10 user-defined temperature/time segments—enabling unattended overnight or multi-stage incubation protocols
- RS-485 serial interface compliant with Modbus RTU protocol for integration into lab-wide monitoring networks or SCADA systems
- Non-volatile parameter memory retains settings—including time, temperature, and program sequence—during unexpected power interruption, with automatic resumption upon restoration
- Large-view tempered glass door with anti-fog coating and magnetic door seal minimizes thermal disturbance during observation
Sample Compatibility & Compliance
The BPX-272 accommodates standard microbiological vessels including Petri dishes (up to 150 mm diameter), test tubes (16 × 150 mm), culture flasks (T75, T175), and multiwell plates (6–96-well). Its dry incubation configuration excludes condensation-related contamination risks, supporting ISO 11137 (sterility assurance), USP / (microbial enumeration), and CLSI M22-A3 (aerobic bacterial culture) workflows. While not certified for IEC 60601 medical device use, it meets CE marking requirements for laboratory equipment under the Low Voltage Directive (2014/35/EU) and EMC Directive (2014/30/EU). Documentation packages include factory calibration certificates (traceable to NIM, China) and conformity declarations.
Software & Data Management
The incubator supports third-party data acquisition via RS-485 using standard ASCII command sets. When paired with BOXUN’s optional monitoring software (v3.2+), users gain access to real-time graphical trending, configurable alarm thresholds (e.g., overtemperature, timeout), audit-trail-enabled event logs, and CSV export for statistical process control (SPC) analysis. Thermal printer integration enables hard-copy recording of temperature profiles meeting FDA 21 CFR Part 11 requirements when deployed with electronic signature and user access controls. GPRS add-on provides SMS alerts for out-of-spec events—critical for unstaffed facilities or satellite labs.
Applications
- Bacterial and fungal cultivation in clinical microbiology and QC labs
- Enzyme kinetics studies requiring precise thermal stabilization between 25°C and 65°C
- Seed germination and plant tissue culture pre-incubation steps
- Accelerated stability testing of excipients and solid-dose formulations (ICH Q1A)
- Incubation of ELISA plates prior to substrate development
- Storage of temperature-sensitive reagents and standards under controlled ambient-plus conditions
FAQ
Does the BPX-272 support humidity control?
No—it is a dry incubator with no integrated humidification system. For applications requiring relative humidity regulation, consider BOXUN’s BHG series CO₂/humidity incubators.
Is the temperature sensor calibrated and traceable?
Yes. Each unit ships with a factory calibration report referencing National Institute of Metrology (NIM) standards; optional UKAS-accredited recalibration services are available.
Can multiple BPX-272 units be monitored centrally?
Yes—via RS-485 daisy-chaining (up to 32 devices) using Modbus addressing, compatible with LabVantage, Thermo Fisher SampleManager, or custom Python/Node-RED implementations.
What safety protections are built-in?
Independent overtemperature cutoff (mechanical backup), door-open alarm, current overload protection, and thermal fuse redundancy ensure compliance with Class II laboratory equipment safety expectations.
Are spare parts and service support available internationally?
BOXUN maintains authorized service partners in North America, EU, and Southeast Asia; consumables (shelves, seals, fuses) and firmware updates are distributed through regional distributors with 48-hour logistics SLAs.
