Percival Scientific SciWhite LED Chamber Arabidopsis Growth Chamber Model AR‑95L2
Optimized LED Growth for Arabidopsis, Lettuce, and Low-Light Plants
The Percival Scientific AR‑95L2 is designed for Arabidopsis thaliana, Brassica species, lettuce, spinach, and other low-light plants, providing precise temperature, airflow, and LED lighting control for reproducible research.
Key Features
Tiered High-Uniformity LED Lighting
Two tiers of LED shelves deliver consistent, programmable light up to 575 µmol m²/s, with dimming in 1% increments.
Precise Environmental Control
Temperature range: 7–44 °C lights ON / 2–44 °C lights OFF, ±1.0 °C stability. Full fresh-air circulation ensures uniform conditions.
Experiment Protection
Dual high- and low-temperature limits with visual and audible alarms automatically protect your experiments.
Large Interior for Multi-Tier Growth
95.9 cu ft interior volume with 28.6 sq ft of usable work area across two tiers, each supporting 27.6″ maximum growing height.
