BOXUN BPX-52 Electrically Heated Constant-Temperature Incubator

Overview

The BOXUN BPX-52 Electrically Heated Constant-Temperature Incubator is a precision-engineered dry incubation system designed for stable, repeatable thermal environments in life science laboratories. It operates on resistive heating principles with forced-air convection, delivering uniform temperature distribution across its 43 L stainless-steel chamber without humidity control—making it ideal for bacterial culture propagation, enzyme activity assays, cell line maintenance (non-CO₂-dependent), and reagent conditioning where moisture-sensitive protocols are required. The unit complies with general laboratory safety standards for Class II electrical equipment (IEC 61010-1) and is engineered for continuous operation under GLP-aligned workflows. Its compact footprint (640 × 485 × 525 mm) supports benchtop integration in QC labs, university teaching facilities, and contract research organizations requiring reliable, low-power thermal stabilization.

Key Features

• Microprocessor-based PID temperature controller with LCD interface displaying real-time setpoint, actual temperature, timer status, and fault codes
• Forced-air circulation system featuring a brushless DC motor and optimized ducted airflow architecture, ensuring ±0.5°C uniformity (measured at nine points per IEC 60068-3-5)
• High-efficiency thermal insulation using composite polyurethane foam and nano-enhanced magnetic door seal, minimizing heat loss and external surface temperature rise
• Two-tier adjustable stainless-steel shelving system (304 grade), supporting flexible load configuration up to 15 kg per shelf
• Programmable multi-step operation: up to 10 temperature/time segments per cycle, with 100-cycle repeat capability for unattended overnight or weekend runs
• RS-485 serial interface compliant with Modbus RTU protocol, enabling integration into centralized lab monitoring systems or data loggers for audit-ready traceability
• Power-loss recovery function retaining all user-defined parameters—including setpoints, timers, and program sequences—upon grid restoration
• Over-temperature alarm with audible/visual alert and automatic heater cutoff at +10°C above setpoint (adjustable threshold)

Sample Compatibility & Compliance

The BPX-52 accommodates standard Petri dishes (up to 150 mm), test tubes (16 × 150 mm), multiwell plates (6–96-well), and small-volume flasks (≤500 mL). Its dry incubation design precludes condensation-related contamination risks, supporting applications such as dry-heat sterilization validation (per ISO 17665-1 Annex B), microbial growth curve analysis (ASTM E2694), and stability testing of lyophilized pharmaceutical intermediates. The device meets CE marking requirements for electromagnetic compatibility (EN 61326-1) and safety (EN 61010-1), and its firmware architecture supports basic 21 CFR Part 11 readiness when paired with validated third-party data acquisition software—enabling electronic signature capture and audit trail generation for regulated environments.

Software & Data Management

While the BPX-52 operates autonomously via its onboard controller, the RS-485 port enables bidirectional communication with host PCs running terminal emulation or custom SCADA interfaces. Users may log temperature profiles at configurable intervals (1–60 sec), export CSV-formatted datasets, and generate time-stamped reports compatible with LIMS platforms. Optional accessories—including an external thermal printer (supporting real-time trend curves) and GPRS-enabled SMS alert module—extend remote oversight capabilities without requiring local network infrastructure. All stored operational logs retain timestamps synchronized to internal RTC (±2 sec/month drift), satisfying minimum documentation requirements under ISO/IEC 17025 Clause 7.7.

Applications

• Bacterial colony isolation and enumeration (e.g., E. coli, S. aureus) per ISO 4833-1 and USP <61>
• Enzyme kinetics studies requiring precise thermal staging (e.g., restriction digest optimization at 37°C or 50°C)
• Plant tissue culture initiation under non-humidified conditions
• Quality control of diagnostic reagents and ELISA kits during accelerated stability testing
• Dry-heat depyrogenation verification for glassware prior to aseptic processing
• Incubation of antibody-coated microplates prior to washing steps in immunoassay development

FAQ

Does the BPX-52 support CO₂ or humidity control?
No. This is a dry, electrically heated incubator with no integrated humidification or gas regulation system.
Can the unit maintain temperature during extended power outages?
It retains programmed parameters after power interruption and resumes operation automatically upon restoration, but does not provide battery backup for active temperature maintenance.
Is calibration certificate included with shipment?
A factory calibration report (traceable to NIM China) is provided; ISO/IEC 17025-accredited calibration is available as a paid service option.
What is the maximum ambient operating temperature for the BPX-52?
Rated for continuous use in environments between 10°C and 30°C, with relative humidity ≤80% RH non-condensing.
Are replacement shelves and door seals available as spare parts?
Yes. Stainless-steel shelves (P/N: BPX-SH-01), nano-magnetic gaskets (P/N: BPX-SEAL-02), and fuses are stocked globally through authorized BOXUN distributors.
