Jihepu BSP-150 Biochemical Incubator

Overview

The Jihepu BSP-150 Biochemical Incubator is a precision-engineered, microprocessor-controlled environmental chamber designed for stable, long-term cultivation and preservation of biological samples under tightly regulated thermal conditions. Utilizing a forced-air convection system with an optimized dual-path airflow architecture—comprising centrifugal blower-driven circulation and an independent fresh-air intake module—the incubator ensures uniform temperature distribution (±1°C) and minimal thermal fluctuation (±0.5°C) across the entire working chamber. Its integrated refrigeration system employs a high-efficiency, internationally certified hermetic compressor and ozone-safe R134a or equivalent non-CFC refrigerant, enabling reliable operation from ambient +5°C up to 60°C and down to 0°C—critical for BOD testing, microbial growth studies, fungal culture maintenance, and plant tissue incubation. The unit complies with fundamental design principles outlined in ISO 13408-1 (aseptic processing), ASTM E171 (standard specifications for environmental chambers), and supports GLP-aligned operational traceability when paired with optional data logging or remote monitoring.

Key Features

• Microcomputer-based PID temperature control with 0.1°C resolution and real-time LCD display of setpoint, actual temperature, and elapsed time
• Patented integrated refrigeration system with auto-defrost functionality—designed to eliminate ice buildup without interrupting temperature stability or consuming additional energy
• Dual-door observation window with insulated double-glass construction minimizes thermal loss while enabling non-intrusive sample monitoring
• Modular interior: mirror-finish stainless steel chamber, three independently adjustable stainless steel shelves, and reinforced cold-rolled steel exterior with electrostatic epoxy coating
• Dedicated 30/60 mm (ID/OD) access ports on left and right side walls for sensor integration, gas supply lines, or external probe routing
• Programmable operation: up to 10 temperature segments per cycle, 99 cycles total; supports ramp-hold profiles for staged incubation protocols
• Comprehensive safety architecture: over-temperature alarm, compressor overheat protection, door-open alert, and automatic restart after power recovery with memory retention

Sample Compatibility & Compliance

The BSP-150 accommodates standard microbiological vessels—including Petri dishes, test tubes, flasks, and multi-well plates—as well as larger botanical specimens and aquatic culture containers. Its sealed chamber design permits controlled-atmosphere applications (e.g., low-O₂ or CO₂-supplemented environments when externally interfaced). While not a certified Class II biosafety cabinet, the unit meets baseline containment requirements for non-pathogenic and Risk Group 1 (RG1) organisms per WHO Laboratory Biosafety Manual (4th ed.). It is routinely deployed in accredited university labs, municipal water quality testing facilities, pharmaceutical QC units, and agricultural research stations performing BOD₅ assays (per ISO 5815-1), microbial enumeration (ISO 4833-1), and seed germination trials (ISTA guidelines). All electrical components conform to IEC 61010-1 safety standards for laboratory equipment.

Software & Data Management

Equipped with an RS-485 serial interface compliant with MODBUS RTU protocol, the BSP-150 enables bidirectional communication with laboratory information management systems (LIMS), SCADA platforms, or custom Python/Node-RED scripts for automated data acquisition. Optional accessories include a thermal printer (supporting time-stamped trend curves), GPRS-enabled SMS alert module (for out-of-specification events), and PC-based monitoring software with audit trail capability—facilitating adherence to FDA 21 CFR Part 11 requirements when configured with user authentication and electronic signature support. Parameter memory retains all settings—including program sequences and alarm thresholds—during unexpected power loss, ensuring continuity in multi-day experiments.

Applications

• Biochemical oxygen demand (BOD) measurement in wastewater and surface water analysis
• Cultivation and maintenance of bacteria (e.g., E. coli, Bacillus subtilis), yeasts, molds, and mesophilic fungi
• Stability testing of probiotics, enzymes, and diagnostic reagents under accelerated aging conditions
• Plant tissue culture initiation, callus induction, and photoperiod-independent germination studies
• Quality control incubation for food microbiology (e.g., APC, coliforms per ISO 6579) and veterinary vaccine production intermediates
• Environmental simulation for ecotoxicology assays involving aquatic invertebrates or algal species

FAQ

What is the minimum operating temperature, and can it maintain sub-ambient conditions?

Yes—the BSP-150 achieves and stabilizes temperatures from 0°C to 60°C, including refrigerated operation below ambient, enabled by its closed-cycle vapor-compression system.

Is the incubator suitable for use with CO₂-enriched atmospheres?

The unit does not include built-in CO₂ regulation; however, its sealed chamber and dual-side access ports allow integration with external gas mixing manifolds and mass flow controllers for modified-atmosphere applications.

Does the device support regulatory compliance for pharmaceutical or clinical lab use?

When equipped with optional data logging, user access controls, and electronic audit trails, the BSP-150 supports alignment with GMP Annex 11, USP , and ISO/IEC 17025 documentation requirements for equipment qualification.

How is temperature uniformity verified during installation qualification (IQ)?

A 9-point temperature mapping protocol—using NIST-traceable calibrated probes placed at defined locations (corners, center, mid-height)—is recommended per ISO 14644-3 and EU GMP Annex 15 guidelines.

Can the incubator be validated for sterilization cycles?

No—it is not designed for steam or dry-heat sterilization; validation applies only to thermal performance (IQ/OQ/PQ), not bioburden reduction.
