BOXUN SPX-100B-ZII Biochemical Incubator

Overview

The BOXUN SPX-100B-ZII Biochemical Incubator is a precision-engineered, microprocessor-controlled environmental chamber designed for stable, reproducible temperature regulation across life science and industrial microbiology applications. Based on forced-air convection with variable-speed fan control and a high-efficiency R134a refrigeration system, the unit maintains uniform thermal conditions over its full operating range of 0–60 °C—enabling both ambient and sub-ambient cultivation without frost accumulation. Its robust architecture integrates a cold-rolled steel exterior with electrostatic powder coating, a mirror-finish stainless-steel interior chamber, and vacuum-insulated tempered glass viewing window—ensuring mechanical durability, corrosion resistance, and real-time visual monitoring under controlled lighting (8 W integrated LED). The incubator complies with fundamental design principles outlined in ISO 13408-1 (sterile processing environments) and supports GLP-aligned workflows through traceable temperature logging and power-interruption recovery.

Key Features

• PMMAI-based touchscreen control system with backlit LCD display, offering intuitive navigation for temperature setpoint, timer configuration (0–999 min), and fan speed selection (6 discrete levels)
• High-resolution temperature control (0.1 °C resolution) with ±1 °C fluctuation and ±1.5 °C uniformity at 37 °C—validated per ASTM E2500-13 for laboratory equipment qualification
• Variable airflow management minimizes evaporative loss from culture vessels while ensuring homogenous heat distribution across all shelf positions
• Integrated 220 V AC power outlet inside the chamber enables direct connection of auxiliary devices (e.g., shakers, sensors, or small peripherals) without external cable routing
• Imported low-noise compressor and optimized insulation reduce acoustic emissions to <52 dB(A), supporting placement in shared laboratory spaces
• Comprehensive safety suite includes over-temperature alarm, real-time self-diagnostic reporting, and automatic resumption of prior settings after power interruption

Sample Compatibility & Compliance

The SPX-100B-ZII accommodates standard Petri dishes, multi-well plates, culture flasks (up to 2 L), and test tubes within its 64.8 L internal volume. Its stainless-steel interior and smooth, non-porous surfaces facilitate routine decontamination using ethanol, hydrogen peroxide vapor, or validated biocidal agents—supporting compliance with USP Analytical Instrument Qualification guidelines. The unit’s temperature stability profile meets requirements for BOD5 incubation per ISO 5815-1 and microbial growth studies referenced in CLSI M22-A3. While not certified for Class II biosafety use, it is routinely deployed in non-BSL environments for bacterial, fungal, and algal culture maintenance, seed germination trials, and biochemical assay incubation.

Software & Data Management

The onboard PMMAI controller logs temperature data at user-defined intervals (default: 1 min) and stores up to 30 days of continuous records internally. Data export is supported via USB port (not included) in CSV format for post-processing in Excel or LIMS-integrated platforms. Audit trail functionality captures operator actions—including setpoint changes, timer resets, and alarm acknowledgments—with timestamp and user ID (where configured via network integration). The system adheres to FDA 21 CFR Part 11 foundational expectations for electronic records through password-protected access levels and immutable event logging—though full Part 11 compliance requires external validation documentation and IT infrastructure alignment.

Applications

• Biochemical oxygen demand (BOD) testing in environmental water quality laboratories
• Maintenance and propagation of mesophilic bacteria (e.g., E. coli, Bacillus subtilis) and fungi (Aspergillus niger, Candida albicans)
• Plant tissue culture initiation and callus induction under controlled photoperiod-free conditions
• Enzyme activity assays requiring precise thermal stabilization between 4 °C and 55 °C
• Stability testing of diagnostic reagents and pharmaceutical intermediates per ICH Q1A(R2)
• Aquaculture larval development studies where temperature-dependent ontogeny must be replicated

FAQ

Does the SPX-100B-ZII support humidity control?
No—this model is a dry-air incubator. Humidity regulation is not integrated; users requiring >60% RH should consider BOXUN’s SHP series or paired external humidification systems.
Can the incubator operate continuously at 4 °C?
Yes—the R134a refrigeration system and variable-speed compressor enable stable sub-ambient operation across the full 0–60 °C range without defrost cycles or performance degradation.
Is calibration certificate included with shipment?
A factory calibration report (traceable to NIM, China) is provided. Full ISO/IEC 17025-accredited calibration requires third-party service and is recommended annually for regulated environments.
What is the maximum load capacity per shelf?
Each stainless-steel shelf supports up to 15 kg uniformly distributed. Total payload (3 shelves) must not exceed 45 kg to maintain airflow integrity and thermal uniformity.
How is firmware updated?
Firmware upgrades are performed via USB using BOXUN-provided utility software and require technician-level access credentials—contact BOXUN Technical Support for version-specific release notes and update protocols.
