Percival Scientific Arabidopsis Growth Chamber Model AR-75L2
Low-Light Plant Growth Chamber Optimized for Arabidopsis and Leafy Greens
The Percival Scientific AR-75L2 Arabidopsis Growth Chamber is engineered for plants with lower light intensity requirements, delivering uniform illumination, precise environmental control, and generous vertical growing space. Designed specifically for Arabidopsis thaliana and similar research models, this chamber combines high-output yet finely tunable SciWhite® LED lighting with Percival’s advanced IntellusUltra™ Controller for consistent, repeatable results.
Key Features
- Optimized for Arabidopsis thaliana and low-light plant research
- SciWhite® LEDs enhanced with red spectrum for balanced plant development
- Two-tier stainless steel shelving with exceptional vertical growing height
- Uniform rear-wall airflow for stable conditions across shelves
- Industrial-grade modular cabinet construction with environmentally friendly insulation
Core Technical Highlights
Lighting System
- Each shelf tier illuminated by SciWhite® LEDs enhanced with Red tiles
- LEDs spaced for uniform light distribution across each shelf
- Light intensity programmable up to 350 µmoles/m²/sec, measured at 6″ from LED tiles
- Dimmable from 10–100% in 1% increments
- Lighting fully programmed and controlled via the IntellusUltra™ Controller
Environmental Control & Airflow
- Uniform airflow across shelves via rear-wall air diffusers
- Conditioned air travels the full back wall, over shelves, and returns through ceiling-mounted fans
- Designed to maintain consistent temperature and humidity across both growing tiers
Cabinet Construction
- Modular panel construction with 2″ thick urethane insulation
- Interior and exterior: 22-gauge electro-zinc plated steel
- Cam-type fasteners with vinyl gaskets
- Two 1.25″ diameter access ports
- Stainless steel chamber floor with integrated floor drain and hose assembly
- Cabinet mounted on angle-frame base with heavy-duty swivel casters
Insulation
