BOXUN BXP-280S Microbial Incubator

Overview

The BOXUN BXP-280S Microbial Incubator is a precision-engineered, benchtop-to-floor-standing convection incubator designed for consistent, reliable thermal conditioning of microbiological cultures, cell lines, and environmental samples under controlled non-humidified conditions. It operates on forced-air convection principles, utilizing rear-mounted heating elements and multi-stage fan-driven air circulation to achieve rapid thermal equilibration and high spatial uniformity across its 280 L stainless-steel chamber. Engineered for routine QC microbiology, pharmaceutical stability testing, and academic research labs, the BXP-280S complies with core performance expectations outlined in ISO 13408-2 (aseptic processing), USP (microbiological control), and EU GMP Annex 1 (airborne particulate control when equipped with optional HEPA filtration). Its operational range from ambient +5°C to 100°C supports both mesophilic and thermophilic cultivation protocols, including spore germination, fungal growth, and accelerated stability studies.

Key Features

• 5-inch high-resolution capacitive touchscreen interface with real-time display of setpoint/actual temperature, timer status, fan speed stage, damper position, and system operating mode
• Rear-heating architecture with direct airflow injection into the chamber—reducing 60°C ramp time to ≤15 minutes and improving thermal response fidelity
• Patented internal baffle and perforated rear wall design ensures laminar, symmetric air distribution—validated at ±0.8°C uniformity (at 60°C) per ISO 29183
• Dual-redundant overtemperature protection: primary PID-controlled electronic cutoff + independent mechanical thermostat (fail-safe architecture)
• Programmable temperature profiles: up to 30 segments and 99 cycles, supporting complex ramp/soak/cool sequences with user-defined heating and cooling rates
• Comprehensive data logging: 4 million timestamped entries stored internally; exportable via USB to CSV or Excel-compatible formats for audit-ready recordkeeping
• Configurable ventilation management: 10-position exhaust dampers and 5-step fan speed control enable fine-tuned air exchange rates for oxygen-sensitive or volatile compound applications
• Security and compliance readiness: screen lock with password protection, scheduled start/stop (calendar-based), and optional FDA 21 CFR Part 11–compliant audit trail software

Sample Compatibility & Compliance

The BXP-280S accommodates standard microbiological vessels—including Petri dishes, test tubes, flasks, and multi-well plates—on up to nine adjustable stainless-steel shelves (3 supplied, 6 optional). Its Class 100-compatible airflow configuration (with optional HEPA filter) meets ISO 14644-1 requirements for particle concentration control in critical environments. While humidity is not regulated, the unit’s sealed chamber and positive-pressure airflow minimize external contamination ingress. Calibration and qualification support is provided through NIST-traceable wireless temperature probes (validated at 0°C, 60°C, and 121°C), with accompanying metrology certificates suitable for IQ/OQ/PQ documentation. The system satisfies GLP and GMP environmental monitoring prerequisites when integrated with BOXUN’s validated FDA/GMP Edition monitoring software.

Software & Data Management

Data integrity is maintained via embedded non-volatile memory and timestamped logging at user-selectable intervals (1 s to 60 min). USB export enables offline analysis in third-party tools (e.g., MATLAB, Python pandas, or LabChart). Optional FDA Edition software provides electronic signatures, role-based access control, change history tracking, and automated report generation compliant with 21 CFR Part 11 Annex 11. GPRS-enabled SMS alerts transmit real-time fault notifications—including door-open events, temperature excursions, and power failures—to preconfigured mobile numbers. Remote monitoring integration via Modbus RTU over RS-485 allows centralized lab infrastructure management within existing SCADA or LIMS platforms.

Applications

• Microbial enumeration and identification (ISO 4833-1, AOAC 977.27, USP )
• Pharmaceutical environmental monitoring (viable air/surface sampling incubation)
• Bioburden testing and sterility assurance protocol execution
• Thermal tolerance studies of bacterial endospores and resistant strains
• Yeast and mold growth kinetics under defined thermal regimes
• Educational laboratory instruction in microbiology and biotechnology curricula
• Stability chamber pre-conditioning for packaging or device validation

FAQ

Does the BXP-280S support humidity control?
No—this model is a dry incubator. Humidity regulation is not implemented; users requiring RH control should consider BOXUN’s dedicated humidified incubator series.
Can the unit be validated for GMP use?
Yes—when configured with optional wireless validation probes, HEPA filtration, and GMP Edition software, it supports full IQ/OQ/PQ execution per ASTM E2500 and EU GMP Annex 15 guidelines.
What is the maximum operating temperature and its stability specification?
Maximum setpoint is 100°C; temperature fluctuation is ±0.3°C (measured over 30 s at 60°C), per internal verification against PT100 reference sensors.
Is remote monitoring supported out of the box?
RS-485 Modbus RTU communication is standard; GPRS SMS alerting and cloud-based telemetry require optional hardware modules and subscription-enabled firmware.
How many data points can be stored, and what is the backup method?
Up to 4 million readings are retained in internal flash memory; data export is performed manually via USB drive—no automatic network backup is included without optional software licensing.
