Percival Scientific Reach-In Plant Growth Chamber Model E‑22L
High-Intensity Lighting for Short-Term Plant Growth
The E‑22L Reach-In Chamber is engineered for short plants and forage crops including alfalfa, peanut, potato, and bluegrass. Its single-tier lighted shelving and high-intensity LED lighting make it ideal for rapid growth studies and controlled environment experiments.
Key Features
-
IntellusUltra® Controller: Android-based touchscreen for real-time monitoring and programming of temperature, lighting, humidity, and optional CO₂ enrichment. Features step/ramp programming, deviation alarms, and full event logging.
-
Lighting System: SciWhite LEDs enhanced with Red, intensity programmable up to 680 μmoles/m²/s at 6″, dimmable 10–100% for optimal photosynthesis.
-
Airflow & Circulation: Conditioned air moves through a rear-wall plenum horizontally across each shelf, then vertically upward back to the cooler, maintaining uniform conditions across the work area.
-
Shelving: One tier of white epoxy-coated steel wire shelving per compartment (27″D × 28.8″W), vertically adjustable in ½″ increments with maximum clearance of 20.2″.
-
Refrigeration & Temperature Control: Self-contained air-cooled condensing unit with hot gas bypass system, ensuring precise temperature control, extended compressor life, and no ice buildup. Ceiling-mounted evaporator coils with dual fans provide uniform cooling.
-
Experiment Protection: Adjustable high/low temperature limits, audible and visual alarms, automatic reset ensures safe operation.
-
Durable Construction: Interior 22-gauge steel, exterior 18-gauge steel, stainless steel floor, fully welded seams, floor drain and hose assembly, caster assembly, and leveling legs.
