Percival Scientific Tissue Culture Growth Chamber Model CU-22L
Dual-Environment Chamber for Condensation-Free Plant Cell Culture
The CU-22L Tissue Culture Chamber enables simultaneous experiments under different photoperiods, temperature, and environmental conditions, making it ideal for plant cell culture and tissue culture research. Its unique airflow design, fixed lamp bank, and slide-out shelves prevent condensation on Petri dish lids, ensuring reproducible experimental results.
Features
PetriClear LED Lighting System
-
Two tiers of shelves illuminated by PetriClear LEDs
-
Programmable intensity up to 170 µmol m²/s at 6″ from LEDs
-
SciWhite + Infrared technology prevents condensation on culture plates
-
Dimmable from 10–100% in 1% increments
-
Fully integrated with the IntellusUltra real-time controller for precise environmental management
Shelf-Level Vertical Airflow
-
Conditioned air moves through a rear wall duct and rises slowly through fixed air diffusers at each shelf
-
Diffuser prevents heat transfer from lights, minimizing condensation and maintaining stable culture conditions
IntellusUltra™ Environmental Control
-
Industrial-grade, integrated hardware design
-
Flexible configuration for lighting, temperature, humidity, and optional CO₂ enrichment
-
High-precision experiment protection and diagnostics
-
Dual high and low temperature limit alarms with auto-reset capability
