Overview
The BOXUN SPX-100B-Z is a microprocessor-controlled biochemical incubator engineered for stable, reproducible temperature environments in life science laboratories. Designed according to fundamental principles of thermal convection and heat transfer optimization, it employs forced-air circulation to ensure rapid equilibration and uniform thermal distribution across the chamber. Its operational range of 0–50 °C supports a broad spectrum of biological applications—including microbial culture, BOD testing, enzyme activity assays, seed germination studies, and short-term sample storage—where precise, non-humidified ambient-temperature control is required. Unlike CO₂ or humidity-controlled incubators, the SPX-100B-Z prioritizes thermal stability and mechanical robustness over gas composition or moisture regulation, making it ideal for routine microbiological work, environmental monitoring labs, and academic teaching facilities operating under GLP-aligned workflows.
Key Features
- Forced convection system with optimized airflow path ensures ±2 °C temperature uniformity across the entire 100 L working chamber.
- Microprocessor-based PMMA I control system delivers 0.1 °C resolution and automatic compensation for ambient fluctuations during heating and cooling cycles.
- Dual high-brightness LED display provides simultaneous readout of setpoint and actual chamber temperature, enhancing operational transparency and traceability.
- Compressor-based refrigeration using environmentally compliant R134a enables reliable sub-ambient operation down to 0 °C—critical for psychrophilic organism cultivation and cold-adapted enzyme studies.
- Structural integrity reinforced by cold-rolled steel exterior with electrostatic epoxy coating and mirror-polished 304 stainless steel interior—resistant to corrosion from repeated disinfection protocols.
- Three-position adjustable shelving system (2 standard + 1 optional) supports flexible load configuration; each shelf rated for 15 kg static load, accommodating stacked Petri dishes, flasks, or multi-well plates.
- Power-interruption resilience: non-volatile memory retains user-defined parameters and timer settings, enabling seamless recovery upon power restoration without manual reconfiguration.
Sample Compatibility & Compliance
The SPX-100B-Z accommodates standard laboratory vessels including Petri dishes (up to 150 mm), Erlenmeyer flasks (50–1000 mL), test tubes, and cell culture bottles. Its unhumidified chamber design avoids condensation-related contamination risks common in high-moisture environments—particularly advantageous for long-term bacterial or fungal colony isolation. While not certified for ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, the device’s parameter logging capability, deterministic control logic, and audit-ready timer functionality support integration into GLP-compliant quality systems when paired with validated SOPs. It meets general electrical safety requirements per IEC 61010-1 and complies with RoHS Directive 2011/65/EU regarding hazardous substance restrictions.
Software & Data Management
The SPX-100B-Z operates via an embedded PMMA I control interface with no external PC dependency. All operational parameters—including set temperature, runtime, elapsed time, and current chamber reading—are locally stored in non-volatile memory. The timer function supports both countdown (0–999 h) and elapsed-time tracking modes, generating time-stamped operational records suitable for internal lab documentation. Though it lacks USB or Ethernet connectivity, its deterministic behavior, repeatable ramp profiles, and built-in power-loss recovery align with ALCOA+ data integrity principles when used within defined procedural controls. Users may export observational logs manually via printed records or integrate the unit into broader facility monitoring networks using optional third-party analog signal adapters (0–10 V or 4–20 mA output modules, sold separately).
Applications
- Environmental water quality analysis: BOD5 incubation per ASTM D5210 and ISO 5815-1.
- Microbial culture maintenance: Escherichia coli, Bacillus subtilis, Aspergillus niger, and other mesophilic strains requiring stable 20–37 °C environments.
- Agricultural and fisheries research: Seed viability testing, algal growth trials, and aquatic organism acclimatization at controlled low-temperature setpoints.
- Pharmaceutical QC labs: Stability screening of excipients or intermediate compounds under accelerated storage conditions (e.g., 40 °C/75% RH pre-conditioning followed by 0–50 °C incubation).
- Educational laboratories: Hands-on instruction in microbiology, ecology, and biotechnology where reliability, ease of use, and serviceability are prioritized over advanced automation.
FAQ
Does the SPX-100B-Z support humidity control?
No. This model is a dry-air biochemical incubator and does not include humidification or dehumidification subsystems.
Can the unit operate continuously at 0 °C?
Yes—compressor-based cooling enables sustained operation at the lower limit of its 0–50 °C range, provided ambient room temperature remains ≤30 °C and ventilation clearances are maintained.
Is calibration certificate included with shipment?
Factory calibration verification is performed prior to dispatch; however, a NIST-traceable calibration certificate requires separate request and incurs additional lead time and cost.
What is the maximum allowable ambient temperature for safe operation?
The recommended maximum ambient temperature is 30 °C. Operating above this threshold may compromise cooling efficiency and extend temperature stabilization time.
Are replacement shelves and door gaskets available as spare parts?
Yes—original-equipment stainless steel shelves, silicone door gaskets, and PMMA I controller modules are stocked and available under BOXUN part numbers B-SH-100Z, G-SPXZ, and CTRL-PMMAI, respectively.
