Percival Scientific SciWhite LED Chamber Arabidopsis Growth Chamber Model AR‑100L3
Optimized LED Growth for Arabidopsis, Lettuce, and Low-Light Plants
The Percival Scientific AR‑100L3 is a large-scale growth chamber designed for Arabidopsis thaliana, Brassica species, lettuce, spinach, and other low-light plants. Engineered for precise environmental control, it delivers stable temperature, uniform airflow, and high-fidelity LED lighting across three tiers of growing space.
Features
Tiered High-Uniformity LED Lighting
Three tiers of SciWhite™ LED shelves provide consistent illumination of up to 600 µmol m²/s, ensuring reproducible plant growth.
Precise Environmental Control
Maintain 7–44 °C lights ON / 2–44 °C lights OFF with ±0.5 °C stability. Fresh-air circulation ensures uniform temperature and CO₂ distribution across the chamber.
Robust Experiment Protection
Dual high- and low-temperature safety limits with visual and audible alarms automatically protect experiments. Systems reset automatically when conditions return to range.
Large-Capacity Growth
147.9 cu ft of interior space with 55.1 sq ft of work area, accommodating three tiers of 22.3″ high plant growth, ideal for medium-to-large experiments.
