BOXUN BSP-150 Biochemical Incubator

Overview

The BOXUN BSP-150 Biochemical Incubator is an engineered-for-precision environmental chamber designed to maintain stable, uniform, and programmable temperature conditions essential for microbiological cultivation, biochemical assay incubation, BOD analysis, fungal propagation, and plant tissue culture. It operates on a forced-air convection principle with a patented dual-path airflow architecture—integrating centrifugal blower-driven circulation and an independently controllable fresh-air inlet—to ensure rapid thermal equilibration and minimal spatial gradient across the working chamber. Its integrated refrigeration system employs a high-efficiency hermetic compressor and ozone-safe R134a refrigerant, enabling reliable sub-ambient operation down to 0°C while complying with international environmental directives including EU F-Gas Regulation and Montreal Protocol standards. The unit is constructed with a cold-rolled steel outer shell finished in electrostatic epoxy coating and a mirror-polished 304 stainless-steel interior, supporting long-term corrosion resistance and ease of decontamination under GLP-compliant laboratory practices.

Key Features

• Microprocessor-based PID temperature controller with 0.1°C resolution and real-time LCD display showing setpoint, actual temperature, elapsed time, and alarm status
• Patented multi-layer refrigeration system with auto-diagnostic capability and energy-free periodic defrost cycle—eliminating thermal disturbance during extended incubation protocols
• Forced-air convection via low-noise centrifugal fan and optimized internal ducting ensures ≤±1°C uniformity at 37°C (per ISO 15184:2021 Annex D methodology)
• Dual-mode air management: recirculation-only mode for humidity retention or continuous fresh-air exchange (adjustable flow rate) to suppress CO₂ accumulation and volatile metabolite buildup
• Three-tier adjustable stainless-steel shelving system with load capacity ≥15 kg per shelf; all trays are removable and autoclavable
• Robust safety architecture including over-temperature cut-off, mechanical door latch, audible/visual alarm triggers, and power-failure data retention with auto-recovery function
• RS-485 serial interface compliant with Modbus RTU protocol for integration into centralized lab monitoring systems or LIMS environments

Sample Compatibility & Compliance

The BSP-150 accommodates standard microbiological vessels—including Petri dishes (up to 150 mm diameter), test tubes (16 × 150 mm), Erlenmeyer flasks (up to 2 L), and multi-well plates—without interference from internal obstructions. Its chamber geometry supports simultaneous incubation of heterogeneous sample types requiring identical thermal profiles. The device meets structural and operational requirements referenced in ISO 13408-1 (aseptic processing), ASTM E171 (environmental chamber specifications), and USP (microbiological control of cleanrooms). All electrical components conform to IEC 61010-1:2010 for laboratory equipment safety. The absence of CFCs/HFCs in its refrigeration circuit satisfies EPA SNAP Program eligibility and aligns with institutional sustainability procurement policies.

Software & Data Management

The incubator’s embedded firmware supports up to 10 programmable temperature segments with 99-cycle repetition—enabling complex diurnal or stress-response protocols (e.g., 24-hr ramp-and-hold sequences mimicking circadian temperature shifts). Parameter settings persist through power interruption via non-volatile memory. When connected via RS-485, third-party SCADA platforms or custom Python/Node-RED scripts can log timestamped temperature traces at user-defined intervals (1 sec–60 min). Optional thermal printer output provides traceable hard-copy records compliant with FDA 21 CFR Part 11 when paired with electronic signature-capable software. Audit trail functionality—including operator ID, parameter change history, and alarm event timestamps—is available through the optional PC monitoring suite, supporting ISO/IEC 17025 accreditation workflows.

Applications

• Biochemical oxygen demand (BOD₅) testing per APHA Standard Methods 5210B and ISO 5815-1
• Microbial enumeration (total viable count, coliforms, E. coli) in water, food, and pharmaceutical raw materials
• Fungal isolation and sporulation studies under controlled hygrothermal conditions
• Seed germination assays and early-stage plant tissue culture (e.g., callus induction at 25°C)
• Enzyme activity profiling requiring precise thermal staging (e.g., pre-incubation at 4°C followed by reaction at 37°C)
• Stability testing of diagnostic reagents and clinical specimens per CLSI EP25-A guidelines

FAQ

Does the BSP-150 support humidity control?
No—this model is a temperature-controlled biochemical incubator without active humidification. For applications requiring defined RH levels, BOXUN recommends pairing it with an external saturated salt solution chamber or upgrading to the HCP series humidity-capable models.
Can the incubator operate continuously for 30 days without maintenance?
Yes—its sealed refrigeration loop, brushless DC fan motor, and passive defrost design enable unattended operation for ≥720 hours under nominal load (≤70% chamber volume occupied) and ambient conditions ≤30°C.
Is the RS-485 interface compatible with LabVIEW or MATLAB?
Yes—standard Modbus RTU implementation allows native communication using NI-VISA drivers or MathWorks Instrument Control Toolbox; example configuration files and register maps are provided in the technical documentation package.
What certifications does the unit carry for export to the EU or North America?
It holds CE marking per Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU; UL/cUL certification is pending final review and will be available Q3 2024 for North American distribution channels.
