Percival Scientific Tissue Culture Growth Chamber Model CU-41L5
Precision Environmental Control for Plates, Dishes, and Flasks
The CU-41L5 is a purpose-built tissue culture growth chamber, designed specifically for plant, algal, or microbial cultures in Petri dishes, plates, or flasks. Its shelf-level vertical airflow system minimizes condensation on dish lids while delivering uniform temperature, light, and humidity, ensuring reproducible experimental conditions for sensitive cultures.
Features
PetriClear LED Lighting System
-
Five tiers of shelves lit by PetriClear LEDs with patent-pending SciWhite + Infrared technology
-
Prevents condensation on culture lids
-
Intensity programmable up to 200 µmol m²/s at 6″ from LEDs
-
Dimmable from 10–100% in 1% increments
-
Full integration with the IntellusUltra controller for real-time programming and monitoring
Shelf-Level Vertical Airflow
-
Conditioned air circulates through a rear wall duct and rises vertically through fixed air diffusers at each shelf
-
Low-velocity upward airflow prevents heat transfer from lights and reduces condensation, optimizing conditions for tissue culture experiments
IntellusUltra™ Environmental Control
-
Industrial-grade, integrated hardware design
-
Simultaneous control of up to 7 environmental parameters
-
High flexibility for configuration, expansion, and customization
-
Industry-leading experiment protection and diagnostics
Experiment Protection
-
Dual high and low temperature limits with audible and visual alarms
-
Automatic power shutdown in unsafe conditions, with auto-reset when environment stabilizes
