Percival Scientific SciBrite LED Reach-In Arabidopsis Growth Chamber Model AR-41L3
Compact, Uniform Growth Control for Low-Light Plant Research
The Percival Scientific AR-41L3 is a reach-in Arabidopsis growth chamber designed for laboratories requiring high uniformity, moderate light intensity, and efficient use of vertical space. Optimized for Arabidopsis thaliana, tobacco, and other low-light plant species, this chamber delivers consistent environmental conditions across three growing tiers — supporting reproducible, space-efficient research workflows.
With precision LED lighting, stable airflow, and advanced experiment protection, the AR-41L3 is a reliable solution for academic, biotech, and institutional plant science labs.
Features
Reliable Environmental Stability
Engineered for consistent plant growth conditions, the AR-41L3 maintains stable temperature control suitable for long-term Arabidopsis and low-light cultivation studies.
Uniform, Plant-Optimized LED Lighting
SciWhite™ LEDs enhanced with red spectrum tiles provide evenly distributed illumination across all shelves, delivering up to 405 µmol m²/s at 6″ — ideal for compact, multi-tier growth protocols.
Advanced Control with IntellusUltra™
The IntellusUltra™ Controller enables intuitive programming and monitoring of temperature, lighting, humidity, and CO₂ (optional), supporting diurnal, step, ramp, and non-circadian research programs.
Built-In Experiment Protection
Dual adjustable high and low temperature safety limits with audible and visual alarms automatically shut down chamber power during excursions and self-reset when conditions normalize — protecting valuable experiments.
