Percival Scientific Reach‑In Plant Growth Chamber Model E‑41L1
Precision Plant Growth for Laboratory & Research Environments
The Percival Scientific E‑41L1 is a controlled-environment plant growth chamber built to support a wide range of research applications, from seed germination and seedling development to light-sensitive vascular plant studies and model plant cultivation. Designed for reliability and reproducibility, this chamber provides precise temperature control, programmable high-intensity LED lighting, and robust experiment protection — making it ideal for labs requiring consistent environmental conditions.
Features
High-Intensity LED Lighting: SciWhite LED array with enhanced red spectrum delivers up to 800 µmol m²/s at 6″ from lamps, fully dimmable (10–100%) for customizable light regimes on a single-tier shelf.
Stable Temperature Control: Maintain precise conditions with ±0.5 °C control across a 7–44 °C range (lights ON) or 2–44 °C (lights OFF), ensuring consistent plant growth and reproducible experimental results.
Intuitive IntellusUltra™ Control: Real-time programming of temperature, lighting, humidity, and optional CO₂ enrichment with graphical feedback, alarm logging, and programmable light/event outputs.
Experiment Protection: Dual independent safety limits with audible and visual alarms automatically safeguard experiments and reset once conditions normalize.
Optimized Airflow: Back-wall air diffuser and ceiling fan system provide uniform airflow over the entire shelf, ensuring even temperature and light exposure.
