Jihepu BSP-100 Biochemical Incubator

Overview

The Jihepu BSP-100 Biochemical Incubator is a precision-engineered, microprocessor-controlled environmental chamber designed for stable, long-term cultivation and storage of biological samples under tightly regulated thermal conditions. Operating on a forced-air convection principle with an optimized dual-path air circulation system—including a dedicated fresh-air intake module—the unit ensures homogeneous temperature distribution and continuous atmospheric exchange without compromising setpoint stability. Its integrated refrigeration architecture employs a high-efficiency, low-GWP (Global Warming Potential) refrigerant and a sealed, maintenance-optimized compressor, enabling reliable operation across the full 0°C to 60°C range—critical for BOD testing, microbial growth studies, fungal culture maintenance, plant tissue incubation, and pharmaceutical stability assessments. The incubator complies with fundamental design requirements outlined in ISO 13408-1 (aseptic processing), ASTM E171 (standard specifications for environmental chambers), and supports GLP-compliant workflows through programmable logic and audit-ready parameter retention.

Key Features

• Microcomputer-based PID temperature control with LCD interface displaying real-time setpoint, actual temperature, elapsed time, and countdown timer
• Independent fresh-air ventilation system with manual on/off toggle—adjustable airflow rate maintains O₂ levels and prevents CO₂ accumulation during extended incubations
• Dual-door observation window: outer tempered glass door with inner acrylic panel minimizes thermal loss while enabling non-intrusive visual monitoring
• Patented defrosting mechanism utilizing passive heat redistribution—eliminates power-intensive active defrost cycles and preserves temperature continuity during prolonged operation
• Programmable multi-segment schedule: up to 10 temperature/time segments per cycle, supporting complex protocols such as diurnal rhythm simulation or stepwise acclimatization
• Robust mechanical construction: cold-rolled steel exterior with epoxy electrostatic coating; mirror-finish 304 stainless steel interior chamber resistant to corrosion and routine disinfectants (e.g., 70% ethanol, 1% sodium hypochlorite)
• Comprehensive safety architecture: over-temperature alarm with audible/visual alert, automatic cut-off, and EEPROM-based parameter recovery after power interruption or controller reset

Sample Compatibility & Compliance

The BSP-100 accommodates standard microbiological and botanical sample formats including Petri dishes (up to 150 mm diameter), test tubes (16–25 mm OD), multi-well plates, flasks (Erlenmeyer and baffled), and plant propagation trays. Its internal chamber geometry and shelf load capacity (2 × 15 kg max per shelf) support both static and semi-dynamic experimental configurations. The unit meets structural and performance criteria referenced in USP (Environmental Control for Microbiological Testing), CLSI M22-A3 (Standard for Environmental Monitoring in Controlled Areas), and aligns with the operational expectations of ISO/IEC 17025-accredited laboratories conducting environmental validation per Annex 1 (EU GMP). Optional accessories—including GPRS-based SMS alert modules, thermal printer units (for time-stamped curve output), and PC-based supervision software—enable traceability enhancements required for FDA 21 CFR Part 11 compliance when paired with validated electronic record systems.

Software & Data Management

Equipped with an RS-485 serial interface compliant with Modbus RTU protocol, the BSP-100 enables bidirectional communication with external data loggers, SCADA platforms, or custom LIMS integrations. Firmware supports timestamped parameter logging (temperature, runtime, alarm events) at user-defined intervals (1–60 min), with local memory retaining ≥30 days of operational history. When connected to a host computer via optional USB-to-RS485 converter, users may configure schedules, export CSV-formatted datasets, and generate PDF reports—including calibration verification logs and deviation summaries. All configuration changes are recorded with operator ID (if enabled), timestamp, and pre/post values—fulfilling core ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) for regulated environments.

Applications

• Biochemical oxygen demand (BOD₅) determination per APHA Standard Methods 5210B
• Cultivation and preservation of mesophilic bacteria (e.g., E. coli, Salmonella), yeasts, molds, and lactic acid bacteria
• Seed germination assays, callus induction, and photoperiod-controlled plant tissue culture
• Stability testing of diagnostic reagents, enzyme preparations, and lyophilized biologics
• Environmental monitoring of cleanroom support areas and water quality laboratories
• QC/QA incubation for pharmacopeial microbiological testing (USP , , )

FAQ

Does the BSP-100 support humidity control?

No—this model is a temperature-only incubator. Humidity regulation requires a dedicated humidified incubator (e.g., Jihepu HMI series) or external vapor-saturation integration.

Can the RS-485 interface be used for real-time remote control?

Yes—via Modbus RTU commands, users can read/set temperature, start/stop timers, query alarm status, and retrieve logged data points programmatically.

What is the maximum ambient operating temperature for the BSP-100?

The unit is rated for installation in rooms maintained at ≤30°C ambient temperature with adequate ventilation clearance (≥10 cm on all sides).

Is the stainless steel interior electropolished?

The inner chamber uses standard #4 finish 304 stainless steel—smooth and cleanable, but not electropolished; electropolishing is available as a custom order option.

How often does the unit require preventive maintenance?

Annual inspection of condenser coil cleanliness, door gasket integrity, and sensor calibration verification is recommended per ISO/IEC 17025 Clause 6.4.6.
