Stability Chambers & Environmental Test Chambers
Norlake Scientific configures custom walk-in stability chambers and environmental testing chambers for temperature, humidity, and light control. Each controlled environment chamber is built around the study, room footprint, and facility.
Room conditions, controls, and construction are confirmed during engineering review.
Conditions, sample volume, access patterns, lighting, documentation, and facility constraints determine the right custom environmental chamber or walk-in stability chamber configuration.
Protocol-led
Document long-term, intermediate, accelerated, refrigerated, or frozen conditions.
To 95% RH
Define the control band and humidification demand for the study.
Controlled
Coordinate programmable light where the protocol requires it.
Walk-in scale
Size the walk-in space around samples, carts, shelving, and growth.
Configurable
Plan optional chart recording, alarm packages, remote visibility, and review needs.
Both formats are modular, walk-in systems. The right starting point depends on the room geometry, control profile, and study workflow you need to support.
Refrigeration, humidity, lighting, alarms, and monitoring configured together
Air- or water-cooled systems are matched to the room, with optional redundant refrigeration for failure protection.
Redundant option
Available programmable controls can support temperature, humidity, and lighting, with optional remote tablet monitoring and chart-recording capability.
±0.15°C / ±1.0% RH
Available ultrasonic humidification and optional high/low or power-failure alarm packages can support controlled operation and visibility.
Up to 8 lb water/hr
The chamber format and controls should follow the conditions, volume, and documentation needs of the program.
Engineering review aligns the study conditions, capacity, facility, controls, and documentation into one chamber configuration.
List temperature, humidity, lighting, duration, and operating profile.
Account for samples, shelving, carts, access, and future growth.
Match refrigeration and humidification with selected control, alarm, and redundancy options.
Coordinate optional chart recording, remote monitoring, and review needs.
Stability studies depend on holding tight, controlled conditions over time. Norlake Scientific Enviro-Line stability chambers and environmental rooms regulate temperature, humidity, and light — with optional monitoring and documentation equipment configured around project requirements.
Advanced Enviro-Line control panels regulate air and product temperature and humidity to tight tolerances for repeatable studies.
An ultrasonic humidifier delivers a wide, stable humidity range to hold conditions such as 60% or 75% RH protocols.
Optional chart recorders and Hi/Lo or power-failure alarm packages can support temperature and humidity documentation and sample-protection workflows.
An optional detachable tablet and remote-monitoring configuration can provide refrigeration-performance visibility, error-code alerts, and online data access.
