VELP FOC 200IL Illuminated Refrigerated Incubator

Overview

The VELP FOC 200IL Illuminated Refrigerated Incubator is an engineered platform for controlled-environment biological and microbiological studies requiring precise thermal regulation combined with uniform, spectrally stable illumination. Designed around a dual-function refrigeration-heating system with adaptive PID-based auto-tuning, the FOC 200IL maintains temperature stability within ±0.5 °C across its full operational range of 3–50 °C — a performance benchmark validated under ISO 17025-aligned internal qualification protocols. Its A+-rated compressor-based cooling architecture delivers high thermodynamic efficiency without compromising thermal recovery time after door opening or load changes. The unit integrates VELP’s proprietary ventilation technology — a tangential airflow system with optimized duct geometry and low-turbulence diffusers — ensuring spatial homogeneity in both temperature and light distribution. Unlike conventional incubators relying on passive convection or localized heating elements, the FOC 200IL employs active air recirculation with laminar flow management to eliminate cold/hot spots and minimize vertical thermal gradients (<0.3 °C/m), critical for reproducible seed germination, photoperiod-sensitive insect development, and light-dependent microbial fermentation.

Key Features

• 200 L stainless steel chamber with double-glazed transparent front door — enables non-invasive visual monitoring while preserving thermal integrity and minimizing radiant heat loss
• Dual independent LED illumination racks: each rack houses six horizontally mounted, narrow-spectrum (450–470 nm peak) white LEDs with adjustable intensity (0–100% PWM-controlled), delivering uniform irradiance (>90% uniformity across 150 mm × 150 mm plane) and zero UV emission
• Three-button intuitive digital interface with real-time display of setpoint, actual chamber temperature, illumination status, and timer countdown — no menu navigation required for routine operation
• Integrated internal power socket (230 V AC, 10 A) for auxiliary devices such as shakers, sensors, or humidity modules — isolated from main control circuitry to prevent electromagnetic interference
• Modular sensor expansion: supports up to four VELP BODSensor System 6 units (for dissolved oxygen and respiration rate monitoring) or one BODSensor System 10 (for multi-parameter metabolic profiling) via dedicated I/O ports
• MODBUS RTU communication interface (RS-485) enabling seamless integration into centralized laboratory automation systems or SCADA environments

Sample Compatibility & Compliance

The FOC 200IL accommodates standard culture vessels including Petri dishes (up to 150 mm diameter), multi-well plates (6–96-well), Erlenmeyer flasks (up to 2 L), and small animal cages (max. dimensions: 300 × 200 × 150 mm). Its stable photobiological environment meets requirements for OECD 208 (terrestrial plant toxicity), ISO 11731 (Legionella culture), and USP (microbial enumeration), where defined light/dark cycles and temperature constancy are mandatory. All data acquisition — including timestamped temperature logs, illumination on/off events, and alarm triggers — conforms to GLP principles when used with VELP Ermes and TEMPSoft™. Audit trails include user ID, parameter change history, calibration timestamps, and electronic signatures compliant with FDA 21 CFR Part 11 (when configured with role-based access control and secure authentication).

Software & Data Management

TEMPSoft™ is a Windows-based laboratory software package certified for GxP environments. It supports configuration of complex thermal-light profiles (e.g., 12-h light / 12-h dark cycles with gradual ramping between 22 °C day and 18 °C night), concurrent control of up to ten FOC 200IL units, and automated generation of PDF reports with embedded trend charts. Data export options include CSV (for statistical analysis in R or Python), XML (for LIMS ingestion), and encrypted binary archives meeting ISO/IEC 17025 traceability standards. When paired with VELP Ermes — a cloud-connected IoT platform — the FOC 200IL transmits encrypted telemetry via TLS 1.2 over Ethernet or Wi-Fi. Remote users receive push notifications for out-of-spec conditions (e.g., temperature deviation >±1.0 °C for >30 s), door-open events exceeding 60 s, or illumination failure. Firmware updates, calibration certificate uploads, and diagnostic logs are managed remotely without onsite technician intervention.

Applications

• Photoperiod-controlled plant physiology studies: Arabidopsis thaliana growth assays, crop seed viability testing, and phytochrome-mediated germination kinetics
• Entomological research: Drosophila melanogaster circadian rhythm entrainment, parasitoid wasp development under variable light spectra, and colony maintenance of pollinators
• Microbiological applications: aerobic/anaerobic bacterial culture under defined light exposure (e.g., phototrophic Rhodobacter spp.), yeast fermentation optimization, and biofilm formation assays with time-lapse imaging
• Environmental toxicology: algal growth inhibition tests (OECD 201) requiring strict PAR (Photosynthetically Active Radiation) control and thermal stability
• Biochemical process development: enzyme production in light-responsive expression systems and secondary metabolite synthesis in filamentous fungi

FAQ

What is the maximum allowable ambient temperature for continuous operation?
The FOC 200IL is rated for ambient temperatures up to 30 °C at 60% relative humidity. Operation above this threshold may reduce refrigeration efficiency and extend temperature stabilization time.
Can the LED illumination spectrum be customized beyond the standard white output?
No — the integrated LEDs emit fixed-spectrum cool white light (CCT ≈ 6500 K, CRI >80). For monochromatic or tunable spectral applications, external light sources with optical feedthroughs must be used.
Is TEMPSoft™ validation documentation available for regulated laboratories?
Yes — IQ/OQ protocols, URS templates, and 21 CFR Part 11 compliance statements are provided upon request and are included in the VELP Validation Support Package.
How frequently does the system require calibration verification?
VELP recommends quarterly verification using NIST-traceable PT100 probes; full recalibration is advised annually or after any physical impact or firmware update.
Does the MODBUS interface support write commands for remote setpoint adjustment?
Yes — register mapping includes writable parameters for temperature setpoint, illumination on/off state, and timer duration, enabling full supervisory control from PLC or LabVIEW environments.
