Percival Scientific Drosophila Rearing Chamber Model DR-41VL
Optimized Environmental Control for Drosophila Research
The DR-41VL Drosophila Chamber is specifically designed for rearing Drosophila melanogaster. Its vertical LED lighting, precise temperature control, and customizable humidity system provide a stable and reproducible environment, ideal for genetic, developmental, and behavioral studies.
Features
IntellusUltra™ Environmental Controller
Industrial-grade, real-time controller designed for simultaneous regulation of temperature, lighting, and humidity
Flexible architecture allows for expansion, customization, and remote monitoring (optional IntellusUltra Connect)
Experiment protection with advanced diagnostics and automated alarms
Vertical LED Lighting System
-
Linear LEDs vertically mounted on each side of each shelf
-
Programmable intensity up to 120 µmol m²/s at 6″ from LEDs
-
Dimmable from 5–100% for precise light conditions
-
Controlled via IntellusUltra real-time controller
Humidity Control for Drosophila
-
Additive humidity: up to 85% ±10% (lights on, 15–30°C)
-
Up to 90% ±10% (lights off, 15–30°C)
-
Requires de-mineralized water supply with 1/2″ MPT connection
-
Optional dehumidifier sensor for fine-tuned moisture regulation
