BOXUN BXP-530S Microbial Incubator

Overview

The BOXUN BXP-530S Microbial Incubator is a high-performance, programmable forced-air incubation system engineered for precise and reproducible temperature-controlled cultivation of bacteria, fungi, yeasts, and other microorganisms in clinical microbiology laboratories, pharmaceutical QC environments, and academic research settings. It operates on convection-based thermal regulation using rear-mounted heating elements and a multi-stage axial fan system, ensuring rapid thermal response and minimal spatial gradient across the 530 L working chamber. Unlike humidity-controlled incubators, the BXP-530S is optimized for dry-heat applications—including sterilization validation support, thermal stability testing, and non-hygroscopic microbial growth studies—where strict temperature fidelity and air purity are prioritized over moisture management. Its architecture complies with fundamental design principles outlined in ISO 13408-2 (aseptic processing), ASTM E2500 (verification of pharmaceutical equipment), and supports alignment with FDA 21 CFR Part 11 when configured with optional GMP/FDA-compliant software and audit-trail-enabled data logging.

Key Features

• 5-inch high-resolution capacitive touchscreen interface with real-time display of setpoint/actual temperature, timer status, fan speed stage, exhaust damper position, and operational mode
• Rear-heating configuration enabling direct airflow into the chamber—reducing warm-up time to 60°C in ≤25 minutes and improving thermal efficiency
• Optimized internal airflow path with strategically placed perforated rear wall and top/bottom baffle plates, achieving ±0.5°C temperature uniformity (measured per ISO 13408-2 Annex C at 60°C)
• Programmable 30-segment, 99-cycle profile capability with ramp/soak control, including user-defined heating and cooling rate constraints
• Dual independent over-temperature protection: primary PID-controlled sensor loop + secondary mechanical thermal cutoff switch (fail-safe redundancy)
• Five-level adjustable fan speed and ten-step exhaust damper control—enabling fine-tuned air exchange rates (ACH) for diverse biological load conditions
• Comprehensive data management: onboard storage of up to 4 million timestamped temperature readings; export via USB to CSV or Excel-compatible formats
• RS-485 Modbus RTU communication protocol support for integration into centralized laboratory monitoring systems (e.g., DeltaV, Siemens Desigo, or custom SCADA)

Sample Compatibility & Compliance

The BXP-530S accommodates standard microbiological containers including Petri dishes (up to 150 mm), test tubes (16–25 mm OD), culture flasks (up to 2 L), and multi-well plates. Its stainless-steel interior (SUS304) and smooth, crevice-free chamber geometry facilitate cleaning and reduce biofilm retention risk. While not rated for sterile operation out-of-the-box, optional HEPA-filtered air intake (Class 100 clean air per ISO 14644-1) can be installed to meet ISO 5 requirements for critical process support. The unit is compatible with IQ/OQ/PQ validation protocols and includes traceable calibration points (0°C, 60°C, 121°C) certified per ISO/IEC 17025-accredited metrology providers. Optional wireless temperature sensors (rated to 130°C) enable mapping studies compliant with EU Annex 15 and USP .

Software & Data Management

Data integrity is ensured through configurable audit trail functionality in the optional FDA/GMP Edition software, which enforces electronic signatures, role-based access control, and immutable record retention per 21 CFR Part 11 Subpart B. The system logs all parameter changes, alarm events, door openings, and manual overrides with UTC timestamps. Raw temperature histories are stored with millisecond resolution and may be exported in .csv, .xlsx, or .pdf (with trend curves) formats. Optional GPRS-enabled SMS alerting transmits real-time notifications—including over-temperature, power failure, or door-open events—to preconfigured mobile numbers, supporting 24/7 remote oversight in unattended facilities.

Applications

• Bacterial endotoxin testing (BET) incubation per USP
• Microbial limit testing and bioburden enumeration (Ph. Eur. 2.6.12, USP )
• Antimicrobial susceptibility testing (AST) plate incubation
• Thermal validation of depyrogenation tunnels and dry-heat sterilizers
• Stability-indicating assay development under accelerated conditions (ICH Q1A)
• Environmental monitoring media incubation in Grade A/B cleanrooms
• Research-scale thermophile or mesophile culture maintenance

FAQ

Does the BXP-530S support humidity control?
No. This model is a dry-air incubator designed for temperature-critical, non-hygroscopic applications. Humidity control is not integrated and cannot be retrofitted.
Can the unit be validated for GMP use?
Yes—when equipped with optional FDA/GMP software, wireless mapping probes, and calibrated reference sensors, it meets baseline requirements for equipment qualification under EU GMP Annex 15 and FDA Process Validation Guidance.
What is the maximum operating temperature and its verification method?
The maximum setpoint is 100°C. Thermal performance at elevated temperatures is verified using NIST-traceable Class A PT100 sensors and documented per ISO 17025 calibration certificates.
Is the internal chamber material autoclavable?
No—the stainless-steel chamber is not designed for autoclave exposure. Cleaning must follow validated disinfection protocols using ethanol, hydrogen peroxide vapor, or quaternary ammonium compounds.
How many shelves can be installed simultaneously?
Three shelves are supplied as standard; the chamber supports up to twelve evenly spaced shelves (optional), maintaining ≥80 mm clearance between levels for optimal airflow distribution.
