Percival Scientific Reach‑In Plant Growth Chamber Model E‑41HO
Precision Controlled Plant Growth for Research & Laboratory Environments
The Percival Scientific E‑41HO is a high-intensity, controlled-environment plant growth chamber designed to support advanced research applications, from seed germination and early seedling development to high-light vascular plant studies and specialized photoperiod experiments. Engineered for reproducibility and reliability, this chamber provides precise temperature control, programmable LED lighting, and robust experiment protection for laboratory-grade plant research.
Features
High-Intensity Plant Lighting: SciWhite LED array with enhanced red spectrum delivers up to 1,600 µmol m⁻² s⁻¹ at 6″ from lamps, fully dimmable (10–100%) for flexible light regimes tailored to species and experiment needs.
Accurate Environmental Control: Maintain stable conditions with ±0.5 °C control across a broad range (7–44 °C lights ON / 2–44 °C lights OFF), ensuring reproducibility for sensitive plant studies.
Flexible, Intuitive Control: IntellusUltra™ Controller allows real-time programming of temperature, lighting, humidity, and optional CO₂, plus graphical performance feedback and alarm logging.
Experiment Protection: Dual safety limits with visual and audible alarms automatically safeguard against temperature excursions, resetting automatically when conditions normalize.
Optimized Airflow & Growth Conditions: Custom air diffuser circulates air uniformly across shelves, maximizing light exposure and temperature consistency.
