Percival Scientific SciWhite LED Chamber Algae Growth Chamber Model AL-22L
High-Intensity LED Growth for Algae and Short Plants
The Percival Scientific AL-22L is a dual-tier algae growth chamber engineered for laboratory research requiring high light intensity and precise environmental control. Ideal for algae in flasks or short-stature plants, this chamber delivers uniform light distribution, stable temperature, and controlled airflow across both shelves for reproducible experimental results.
Features
High-Intensity Multi-Tier LED Lighting
Two tiers of SciWhite™ LED tiles deliver up to 350 µmol m²/s at 6″, ideal for algae species with higher light requirements. Fully dimmable from 10–100% to match experimental needs.
Precise Environmental Control
Maintain a temperature range of 7–44 °C lights ON / 2–44 °C lights OFF with ±0.5 °C precision. Airflow is distributed evenly across shelves for consistent growth conditions.
Robust Experiment Protection
Dual high- and low-temperature safety limits with visual and audible alarms automatically protect samples. Systems reset automatically when conditions return to range.
Compact, Flexible Design
Two adjustable shelves with a total work area of 10.8 sq ft maximize cultivation space while maintaining a manageable footprint in the lab.
