Percival Scientific SciBrite LED Arabidopsis Chamber Model AR-36L3
Precision Low-Light Plant Growth with Specialized Tissue Culture Airflow
The Percival Scientific AR-36L3 is a versatile, research-grade Arabidopsis growth chamber designed for low-light plant cultivation and plant tissue culture applications within a single platform. Engineered with a specialized vertical airflow delivery system, this chamber supports traditional potted plants as well as tissue culture plates, dishes, and flasks—making it an ideal dual-use solution for modern plant science laboratories.
With consistent environmental control, plant-optimized LED lighting, and insulated shelf-level airflow, the AR-36L3 delivers reproducible conditions critical for both whole-plant physiology and in-vitro research.
Features
Dual-Use Airflow Design
A specialized rear-duct and fixed diffuser system delivers gentle, vertical airflow through each shelf, insulating experiments from heat generated by underlying light fixtures—ideal for tissue culture plates, flasks, and sensitive plant material.
Low-Light Optimized LED Illumination
SciWhite™ LEDs enhanced with red spectrum tiles provide uniform light delivery up to 350 µmol m²/s at 6″, optimized for Arabidopsis, tobacco, and other low-light species.
Advanced IntellusUltra™ Control Platform
The IntellusUltra™ Controller enables precise scheduling of temperature, lighting, humidity, and optional CO₂ control with graphical feedback and alarm logging.
Built-In Experiment Protection
Independent high and low temperature safety limits with audible and visual alarms protect valuable research material and automatically reset when conditions stabilize.
