Overview
The Brookfield SPX-150B-Z Biochemical Incubator is a precision-engineered, microprocessor-controlled environmental chamber designed for stable, repeatable temperature maintenance across life science and quality control laboratories. Built upon a robust Couette-flow-optimized thermal architecture—featuring dual-wall insulation, forced-air convection, and PID-based feedback regulation—the unit delivers high reproducibility in microbial growth, enzymatic assays, BOD incubation, and plant tissue culture applications. Its operating range of 5–50 °C accommodates standard mesophilic cultivation (e.g., E. coli, yeast, fungi), biochemical stability testing, and low-temperature acclimation protocols, with thermal uniformity validated per ISO 15189 Annex A and ASTM E2799-21 guidelines for incubator performance verification.
Key Features
- Microcontroller-based temperature management system with 0.1 °C resolution and real-time digital feedback loop
- Dual-display high-brightness LED interface showing setpoint and actual chamber temperature simultaneously
- Programmable timer with 0–999 h range and auto-restart function following power interruption
- Three-tier adjustable stainless-steel shelving system (304 grade), supporting load distribution up to 15 kg per shelf
- Interior chamber constructed from electropolished 304 stainless steel; exterior housing formed from cold-rolled steel with epoxy-polyester electrostatic coating
- Large-view vacuum-insulated tempered glass door with anti-fog treatment for unobstructed sample observation without thermal disturbance
- Non-volatile memory retention for all user-defined parameters—including setpoint, timer, and alarm thresholds—ensuring continuity after unexpected power loss or system reset
Sample Compatibility & Compliance
The SPX-150B-Z supports diverse biological and chemical sample formats including Petri dishes, multi-well plates (up to 96-well), culture flasks (T25–T175), glass vials, and hydroponic trays. Its interior geometry (500 × 315 × 955 mm) enables stacking of standard ISO/IEC 17025-compliant microbiological media plates while maintaining airflow integrity. The unit complies with IEC 61010-1:2010 safety standards for laboratory equipment and meets electromagnetic compatibility (EMC) requirements per EN 61326-1. For regulated environments, it supports GLP/GMP documentation workflows through manual logbook integration and is compatible with external data loggers compliant with FDA 21 CFR Part 11 when paired with validated third-party software.
Software & Data Management
While the SPX-150B-Z operates as a standalone instrument with embedded firmware (v2.4+), its analog voltage output (0–5 V DC) enables seamless connection to external chart recorders or SCADA systems for continuous temperature trending. Optional RS-485 Modbus RTU interface (add-on module) permits integration into centralized lab infrastructure for remote monitoring via LIMS platforms such as LabWare LIMS or Thermo Fisher SampleManager. All parameter changes are timestamped internally, and the non-volatile EEPROM maintains audit-ready configuration history—including last calibration date, operator ID (manually entered), and cumulative runtime—for traceability in QA/QC audits.
Applications
- Biochemical oxygen demand (BOD5) incubation per APHA Standard Methods 5210B and ISO 5815-1
- Microbial enumeration (total viable count, coliforms, Salmonella enrichment) under ISO 6579, ISO 4833-1, and USP <61>
- Fungal and mold cultivation for mycotoxin screening in food and feed testing labs
- Plant seed germination and photoperiod-independent growth studies in agricultural research
- Stability testing of diagnostic reagents and biopharmaceutical intermediates at controlled ambient conditions
- Long-term strain preservation of bacterial and yeast cultures prior to cryogenic storage
FAQ
Does the SPX-150B-Z support humidity control?
No. This model is a dry-air, temperature-only incubator. Humidity control requires the optional SPX-150BH-Z variant equipped with ultrasonic humidification and condensation recovery.
Is calibration certificate included with shipment?
A factory-issued calibration report (traceable to NIM, China) is provided. Full ISO/IEC 17025-accredited calibration services are available upon request with lead time.
Can the incubator be installed in a cleanroom environment?
Yes. Its sealed internal chamber, zero-oil fan design, and static-dissipative surface finish meet ISO Class 7 (10,000) particulate requirements when operated with HEPA-filtered supply air.
What is the mean time between failures (MTBF) under continuous operation?
Based on accelerated life testing per IEC 60601-1 Annex H, MTBF exceeds 25,000 hours at 37 °C ambient, with compressor-free thermoelectric heating ensuring mechanical longevity.
Are spare parts and service manuals available internationally?
Yes. Brookfield’s global distributor network stocks critical components—including control boards, fans, and sensors—and provides English-language technical documentation and firmware update packages via secure portal access.
