Percival Scientific SciBrite Reach-In Arabidopsis Growth Chamber Model AR-66L2
Optimized Growth Conditions for Arabidopsis & Low-Light Plant Research
The Percival Scientific AR-66L2 is a controlled-environment Arabidopsis growth chamber engineered for laboratories conducting low- to moderate-light plant research. Purpose-built for Arabidopsis thaliana and similar species, this chamber delivers uniform LED lighting, precise temperature control, and stable airflow — ensuring reproducible experimental outcomes across long-term growth cycles.
Designed with flexibility and experiment protection in mind, the AR-66L2 supports a wide range of academic, biotech, and agricultural research workflows where consistency and control are critical.
Features
Stable Environmental Control
Maintain reliable temperature conditions from 2–44 °C (lights OFF) and 7–44 °C (lights ON), with tight stability (±0.5 °C lights OFF / ±1.0 °C lights ON) to support sensitive plant development stages.
Uniform, Plant-Optimized LED Lighting
SciWhite™ LED lighting enhanced with red spectrum tiles delivers up to 360 µmol m²/s at 6″, evenly distributed across each shelf tier — ideal for Arabidopsis and other low-light crops.
Advanced, Intuitive Control Platform
The IntellusUltra™ Controller enables real-time programming and monitoring of temperature, lighting, humidity, and CO₂ (with optional modules), supporting diurnal, step, ramp, and non-circadian growth protocols.
Built-In Experiment Protection
Dual adjustable temperature safety limits with audible and visual alarms automatically shut down power during excursions and self-reset once conditions return to range — protecting valuable research material.
