ARALAB FitoClima 600 Biochemical Incubator

Overview

The ARALAB FitoClima 600 is a high-precision, programmable biochemical incubator engineered for demanding life science applications requiring tightly controlled temperature and humidity environments. Designed and manufactured in Portugal by ARALAB—a company with over 35 years of expertise in climate simulation systems—the FitoClima 600 implements a dual-chamber refrigeration architecture with independent PID-controlled heating and cooling circuits, enabling stable operation across the full range of −5 °C to +45 °C. Its integrated humidification system utilizes ultrasonic vaporization coupled with a condensate recovery loop, delivering precise RH control from 20% to 95% without compromising internal cleanliness or sample integrity. The unit complies with ISO 14644-1 Class 8 cleanroom-compatible air handling standards and features a fully insulated double-wall construction with low-emission polyurethane foam (CFC-free), minimizing thermal bridging and energy consumption. Unlike basic benchtop incubators, the FitoClima 600 is validated for long-term stability testing per ICH Q1A(R2) and USP , making it suitable for pharmaceutical stability studies, plant physiology research, microbial culture under non-ambient conditions, and enzymatic activity assays where environmental reproducibility is critical.

Key Features

• Dual-circuit climate control system with independent compressor-based cooling and PTC resistive heating—enabling seamless transition between sub-zero and elevated temperatures without overshoot or hysteresis
• Microprocessor-based controller with real-time logging, 16-point calibration capability, and user-defined ramp/soak profiles (up to 99 segments)
• Stainless steel interior chamber (AISI 304) with seamless welds and rounded corners for ease of decontamination; compatible with ethanol, hydrogen peroxide vapor (HPV), and VHP® sterilization protocols
• Three independent fan-assisted air circulation zones with adjustable airflow velocity (0–1.2 m/s) and directional louvers to minimize thermal stratification
• Integrated humidity sensor with automatic drift compensation and self-diagnostic function; humidity generation verified traceable to NIST-certified hygrometers
• Full data audit trail compliant with FDA 21 CFR Part 11 requirements when used with optional ARALAB DataLogger Pro software and electronic signature module

Sample Compatibility & Compliance

The FitoClima 600 accommodates standard microbiological vessels—including Petri dishes, multi-well plates (6–96-well), Erlenmeyer flasks (up to 2 L), and tissue culture stacks—on its four standard 630 mm × 510 mm stainless steel shelves. Each shelf supports up to 18 kg uniformly distributed load, and optional reinforced shelving permits expansion to ten levels for high-throughput workflows. Chamber geometry ensures ≥95% volumetric uniformity at all operating points, validated per ASTM E145-22 Annex A3 for forced-air thermal uniformity testing. The unit meets EN 61000-6-3 (EMC emission) and EN 61000-6-2 (immunity) standards, carries CE marking under the EU Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU, and conforms to GLP/GMP documentation requirements for laboratory equipment qualification (IQ/OQ/PQ). Optional IQ/OQ documentation packages are available upon request.

Software & Data Management

ARALAB’s proprietary ClimateControl Suite provides local and remote supervision via Ethernet (TCP/IP) or USB interface. The software enables continuous monitoring of temperature, humidity, door status, alarm history, and system diagnostics, with configurable email/SMS alerts for deviation events. All logged parameters are stored in encrypted .CSV and binary formats with time-stamped metadata, supporting automated backup to network drives or cloud storage. When paired with the optional DataLogger Pro add-on, the system generates ALCOA+ compliant records—including operator ID, timestamp, reason-for-change annotations, and electronic signatures—required for regulatory submissions under FDA, EMA, and PMDA guidelines. Raw data export supports integration with LIMS platforms via OPC UA or RESTful API endpoints.

Applications

• Long-term stability testing of biologics, small-molecule APIs, and excipients per ICH Q5C and Q1E guidelines
• Growth studies of psychrophilic and mesophilic microorganisms under controlled hygrothermal stress
• Seed germination and plant phenotyping experiments requiring diurnal temperature/humidity cycling
• Enzyme kinetics assays sensitive to ambient moisture-induced conformational drift
• Cell culture maintenance during extended hypothermic storage (e.g., primary hepatocytes at 4 °C)
• Material degradation testing of hydrophilic polymers and packaging films under accelerated aging conditions

FAQ

What is the minimum achievable temperature, and how is sub-zero operation maintained without frost accumulation?
The FitoClima 600 achieves −5 °C using a cascade refrigeration system with R-449A/R-245fa dual-stage compression. Frost formation on evaporators is prevented by periodic hot-gas defrost cycles synchronized with humidity setpoints, ensuring uninterrupted operation and eliminating manual defrosting.
Is the humidity system compatible with sterile processing environments?
Yes—the ultrasonic humidifier uses only deionized or distilled water (<40 μS/cm conductivity), produces no mineral residue, and includes an integrated UV-C lamp in the water reservoir to suppress microbial growth. The entire humidification path is autoclavable and validated for ISO 14644-1 Class 5 compatibility.
Can the incubator be integrated into a centralized building management system (BMS)?
Yes—via Modbus TCP (RTU over Ethernet) or optional BACnet/IP gateway, allowing real-time parameter readout, alarm forwarding, and remote setpoint adjustment within facility-wide HVAC control networks.
Does ARALAB provide installation qualification (IQ) and operational qualification (OQ) documentation?
Standard IQ/OQ templates compliant with ISO/IEC 17025 and GxP expectations are included. Fully executed, site-specific qualification reports with third-party calibration certificates are available as a value-added service.
What safety certifications apply to the electrical and refrigeration subsystems?
The unit carries TÜV Rheinland certification for electrical safety (EN 61010-1), refrigerant containment compliance (EN 378-2), and fire resistance rating (EN 13501-1, Class B-s1,d0).
