Percival Scientific SciBrite LED Dual-Compartment Arabidopsis Growth Chamber Model AR-22L
Independent Plant Growth Control in a Compact Footprint
The Percival Scientific AR-22L is a dual-compartment Arabidopsis growth chamber engineered to provide two independently controlled environments within a single compact cabinet. Designed specifically for Arabidopsis thaliana research, this chamber allows plants to be grown to maturity under precisely regulated temperature, humidity, and lighting conditions—while enabling parallel experiments, treatment comparisons, or control vs. variable studies.
By combining space efficiency with advanced environmental control, the AR-22L is ideal for laboratories that need experimental flexibility without increasing footprint.
Features
Two Independent Growth Environments
Each compartment operates as its own controlled environment, allowing simultaneous experiments with different temperature, lighting, or humidity parameters in one chamber.
Plant-Optimized LED Lighting
SciWhite™ LEDs enhanced with red spectrum tiles deliver uniform illumination across each shelf, providing up to 350 µmol m²/s at 6″ for Arabidopsis growth through maturity.
Advanced IntellusUltra™ Control
The IntellusUltra™ Controller enables intuitive programming of environmental variables, supporting diurnal cycles, ramping profiles, and optional humidity and CO₂ control.
Reliable Experiment Protection
Dual temperature safety limits with audible and visual alarms protect valuable plant material and automatically reset once conditions stabilize.
