Percival Scientific Tissue Culture Growth Chamber Model CU-22L
Dual-Environment Chamber for Condensation-Free Plant Cell Culture
The Percival Scientific 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
