PhotoStability Chamber

Photostability chambers are specifically designed to perform near UV and visual light testing with fluorescent lamps per ICH Q1B Guidelines,

Allyone offers two choices for your photostability chambers:

Photostability Chamber (with Lux & UV Light testing) &Photostability Chamber (with Temperature & RH Control)The study as per the guideline is performed to should identify precautionary measures needed in manufacturing or in formulation of the product, and if light resistant packaging is needed. The samples are tested both pre & post photostability studies, i.e. exposure for any changes in appearance, clarity, or colour (physical properties) & for degradation (chemical).
Technical Specification:

Standard Chamber Features & Provisions:

Construction:
Dynamically Designed PUF filled Double walled, Inner Tank & outer body with SS 304, PUF Density 40kg/m3 with 60 mm thickness

Sample Storage: SS Trays.

Door: PUF Insulated External door mounted with imported hinges & locks, Inner glass doors with latches. Door frame is secured with silicone rubber gasket on entire perimeter to ensure air tight, leak tight chamber.

Door Operation: Biometric &/or Password protected-from software & HMI

UV & Fluorescent Lights: As per ICH Guidelines-1.2 Million Lux Hours of visible light and 200 watt Hr/m2 of UV light.
 Auto shut Off after specified exposure level of Lux & UV Intensity.
Individual Microprocessor based device is provided to start exposure of UV and Fluorescent lights as required. 
UV light is switched off automatically once inner glass door is opened to prevent hazardous exposure: for Human safety.
Samples can be tested under Fluorescent light or U.V. lights separately as well as combine as per test requirement.

Optional System:

Allyone Photostability Chambers can be with Temperature or with Temp & RH (Humidification)Lux meter, UV Meter
Printer Interface (for measuring Lux & UV intensity)
