Yoyilab SPX-150 Biochemical Incubator

Overview

The Yoyilab SPX-150 Biochemical Incubator is a precision-engineered, forced-air laboratory incubator designed for stable, reproducible thermal environments essential in microbiological culture, environmental testing, pharmaceutical quality control, and life science research. It operates on a dual-mode thermoregulation principle—integrating compressor-based refrigeration with resistive heating—to maintain setpoint temperatures across the full 0–65 °C range. Unlike natural convection units, its centrifugal blower ensures uniform airflow distribution throughout the chamber, minimizing thermal gradients and supporting consistent growth kinetics for bacteria, fungi, yeasts, and other mesophilic or psychrotolerant microorganisms. The system complies with fundamental operational requirements outlined in ISO 13408-1 (aseptic processing), ASTM E1269 (thermal stability testing), and USP (pharmaceutical stability testing environments), making it suitable for GLP-compliant workflows where traceable temperature integrity is mandatory.

Key Features

• Robust chamber construction: Cold-rolled steel exterior with electrostatic epoxy powder coating; mirror-finish 304 stainless steel interior with radius-corner design for seamless cleaning and reduced microbial retention.
• Dual-layer insulated door with high-transparency tempered glass and magnetic gasket seal—enables real-time visual monitoring without compromising thermal stability or increasing recovery time.
• Intelligent PID temperature control system with 0.1 °C resolution, programmable timer (1–9999 minutes), and automatic power-loss recovery that retains all user-defined parameters and resumes operation upon restoration.
• Over-temperature deviation alarm with independent hardware cutoff circuitry—prevents sample loss during sensor drift or controller failure.
• Ergonomic mobility: Four swivel casters (two with locking brakes) plus adjustable leveling feet ensure stable placement on uneven laboratory floors while enabling repositioning without disassembly.
• Modular architecture supports optional accessories including RS485 communication interface with PC software (for data logging and remote parameter adjustment), embedded thermal printer (for audit-trail hardcopy), BOD-compatible sockets, and multi-segment programmable temperature profiles.

Sample Compatibility & Compliance

The SPX-150 accommodates standard Petri dishes, test tubes, flasks, and multi-well plates on two independently height-adjustable stainless steel shelves. Its ±1.5 °C temperature uniformity (measured at 25 °C per IEC 61000-4-3 test conditions) meets minimum acceptance criteria for ISO/IEC 17025-accredited microbiology labs performing water quality analysis (e.g., APHA 9215B for heterotrophic plate count), BOD₅ incubation (ASTM D5210), and fungal preservation (ATCC guidelines). The unit is CE-marked for electromagnetic compatibility (EMC Directive 2014/30/EU) and low-voltage safety (LVD Directive 2014/35/EU). Optional RS485 integration enables compliance with FDA 21 CFR Part 11 when paired with validated data acquisition software featuring electronic signatures, audit trails, and role-based access control.

Software & Data Management

While the base model features an intuitive 5.7-inch LCD interface for local operation—including simultaneous display of setpoint, real-time chamber temperature, elapsed time, and remaining timer—the optional RS485 module unlocks advanced data governance capabilities. When connected to Yoyilab’s LabLink™ PC software (v3.2+), users can export timestamped temperature logs in CSV format, generate calibration reports aligned with ISO/IEC 17025 clause 6.4.10, and configure alarm notifications via email or system alerts. All logged data includes metadata such as operator ID, instrument serial number, and environmental ambient readings—supporting full traceability during regulatory audits under GLP or GMP frameworks.

Applications

• Microbial culture and maintenance: Long-term storage of bacterial strains (e.g., E. coli, Bacillus subtilis) and fungal isolates (Aspergillus niger, Candida albicans) at species-specific optimal temperatures.
• Environmental monitoring: Incubation of membrane filtration samples for coliform detection (EPA Method 1603), total viable counts in drinking water (ISO 6222), and activated sludge respiration assays.
• Pharmaceutical QC: Stability testing of raw materials and finished products per ICH Q1A(R2); sterility test incubation per USP .
• Agricultural and aquaculture research: Seed germination studies, algal biomass propagation, and fish egg incubation under controlled thermal regimes.
• Academic teaching labs: Hands-on instruction in microbial physiology, enzyme kinetics, and environmental microbiology where repeatable, documented thermal conditions are pedagogically critical.

FAQ

What is the maximum ambient temperature at which the SPX-150 maintains specified performance?
The unit is rated for continuous operation in ambient environments between +5 °C and +30 °C. Performance validation (uniformity, fluctuation, recovery time) assumes 20 °C ambient and 50% RH per IEC 60068-3-5.
Does the incubator support validation protocols required for ISO 13485-certified medical device manufacturers?
Yes—when equipped with the RS485 interface and LabLink™ software, the system supports IQ/OQ documentation packages, including mapping reports, alarm verification tests, and deviation tracking aligned with Annex 11 and ISO 13485:2016 clause 7.5.10.
Can the internal chamber be sterilized using vaporized hydrogen peroxide (VHP)?
The stainless steel interior and silicone door gasket are compatible with VHP decontamination cycles (≤1000 ppm, 30–60 min exposure); however, the control electronics and display must be protected or powered down per manufacturer’s decon SOP.
Is third-party calibration certification available?
Yoyilab provides NIST-traceable calibration certificates (optional add-on) performed using Fluke 1524 loggers and accredited reference standards, compliant with ISO/IEC 17025:2017 clause 6.5.
What safety certifications does the SPX-150 hold for international shipment?
It carries CE marking for EMC and LVD directives, RoHS 2011/65/EU compliance, and conforms to IEC 61010-1:2010 for laboratory equipment safety—facilitating customs clearance in EU, UK, Australia, and ASEAN markets.
