Overview
The MEMMERT BIO-FITOCLIMA 25000PH is a precision-engineered walk-in environmental growth chamber designed specifically for long-term, reproducible cultivation of plants, algae, insects, and other model organisms under tightly controlled climatic conditions. Built upon MEMMERT’s proven ClimaPlus® control architecture, the system integrates independent regulation of temperature, relative humidity, air exchange rate, and photoperiodic lighting—enabling researchers to replicate natural or experimental microclimates with high fidelity. Unlike conventional incubators or reach-in chambers, the BIO-FITOCLIMA 25000PH provides full human-accessible interior volume (25,000 L), facilitating scalable experiments, multi-tiered cultivation setups, and hands-on intervention without compromising environmental stability. Its robust double-wall insulation, hermetically sealed door gasketing, and PID-controlled refrigeration/heating circuitry ensure minimal thermal drift (< ±0.3 °C at setpoint) and rapid recovery after door openings—critical for maintaining physiological consistency across extended biological assays.
Key Features
- Stainless steel interior and adjustable shelving system—fully removable, load-rated up to 100 kg per shelf, optimized for ergonomic access and cleaning between experiments
- ClimaPlus® 7-inch full-color touchscreen interface with intuitive drag-and-drop programming: supports up to 99 multi-step profiles, each with independent ramp/soak parameters for temperature, humidity, and light intensity
- LED-based illumination system (optional, configurable spectrum: white, red/blue, or full PAR range) with dimmable output (0–100 %) and programmable photoperiod scheduling (e.g., 16 h light / 8 h dark)
- Dual-sensor humidity control using capacitive RH sensors with automatic drift compensation and condensation-resistant design—ensuring stable moisture delivery even during frequent cycling
- Integrated air circulation management: laminar airflow distribution via rear-mounted centrifugal fans with variable-speed control, minimizing turbulence-induced stress on delicate seedlings or cultures
- Remote monitoring and alarm escalation via Ethernet/Wi-Fi: email/SMS alerts triggered by out-of-spec conditions, with timestamped event logs exportable in CSV or PDF format
Sample Compatibility & Compliance
The BIO-FITOCLIMA 25000PH accommodates diverse biological sample formats—including Petri dishes, Magenta boxes, tissue culture flasks, hydroponic trays, insect rearing cages, and potted plant arrays—without requiring chamber modification. Its uniformity specifications meet ASTM E145-22 Class II performance criteria for environmental chambers, with spatial temperature uniformity ≤ ±0.8 °C and humidity uniformity ≤ ±3 % rH across the working volume (validated per ICH Q5C guidelines). The system supports Good Laboratory Practice (GLP) workflows through optional 21 CFR Part 11-compliant software add-ons, including electronic signatures, user role-based access control, and immutable audit trails. All materials in contact with the chamber interior comply with USP Class VI biocompatibility standards and are free of VOC-emitting components.
Software & Data Management
Data acquisition and analysis are enabled via MEMMERT’s ClimaSoft® PC software (Windows-compatible), which provides real-time visualization, historical trend comparison, and automated report generation aligned with ISO/IEC 17025 documentation requirements. Raw sensor data—including temperature, humidity, CO₂ (if equipped), and light irradiance—is logged at user-defined intervals (1 s to 60 min resolution) and stored locally on an internal SD card (up to 32 GB) with redundant backup to network drives. Export formats include .csv, .xlsx, and .pdf with embedded metadata (operator ID, protocol version, calibration dates). Optional cloud integration enables secure, encrypted synchronization with institutional LIMS platforms.
Applications
- Controlled-environment phenotyping of Arabidopsis thaliana, rice, maize, and other model or crop species under defined abiotic stress regimes (drought, heat, cold acclimation)
- Long-duration tissue culture experiments requiring sterility maintenance and precise hormone-response timing
- Algal biomass production trials under modulated light spectra and diurnal cycles
- Insect rearing for entomological research, parasitoid development studies, or vector biology—supporting multi-generational life-cycle monitoring
- Seed germination kinetics and dormancy-breaking protocols across taxonomic groups
- Preclinical evaluation of plant-derived therapeutics under GxP-aligned environmental controls
FAQ
What is the minimum and maximum operating temperature when the lighting system is active?
The chamber maintains a stable temperature range of +5 °C to +45 °C with lights powered on. For sub-zero applications, lighting must be deactivated to enable operation down to 0 °C.
Can humidity be maintained above 80 % rH while illumination is active?
No—maximum humidity under lit conditions is 80 % rH due to thermal load limitations of the integrated humidification system. When lights are off, the system achieves up to 90 % rH.
Is validation support available for IQ/OQ/PQ documentation?
Yes—MEMMERT provides factory-verified qualification packages, including calibrated sensor certificates, uniformity mapping reports, and traceable test protocols compliant with ISO 14644-3 and EU GMP Annex 15.
How is air exchange managed inside the chamber?
A dedicated external air inlet with HEPA filtration (optional) and adjustable exhaust damper allows manual or automated control of air changes per hour (ACH), typically configured between 0.5–3 ACH depending on biological load and CO₂ management needs.
Are custom shelving configurations supported?
Yes—shelving layout, height increments, and load-bearing capacity can be specified during order placement. Stainless steel wire mesh, solid perforated, and anti-static variants are available upon request.
