Photo Stability Chamber
Photo Stability Chamber Model No : SRL / PHSC-10
Application :
Used for large number of sample in hospitals, Research institution. Public health laboratories etc. These chamber can be used for environment testing of production sample & large size equipments where temp. & humidity are to be controlled. They are suitable for storage of electronic components, biological specimen & accelerated ageing test of large number of pharmaceutical samples. They can also used for botany, cytological, Deptsrturents, plan & animal breeding laboratories where controlled condition of temp. humidity & illumination are required.
Ecocentric System :
Chamber runs on the basis of Dewpoint control. Less deviations during short-term door opening & power failure. Less utility area Increased storage area. Low operating cost. Minimum power & water consumption. Reduced deviations. Less breakdowns due to standby refrigeration & humidification system. Due to PLC HMI & controlling through microprocessor based PID Temp. & RH operations the on time of both Temp. & RH system is reduced & efficiency of this system is increased with reduced energy consumption.

Standard Operating Procedure (SOP)
Operational Manual for Controller
IQ,PQ,OQ protocols certificate.
Calibration certificate of all controlling modules with traceability.
Certificate of MOC.
Test Report of chamber prior to supply with mapping certificate.
wiring diagram for ease of service maintenance.
Temp. & Humidity Range :
Temperature Range: +10°C To +60°C
Resolution : 0.1°C, Accuracy : + 0.2°C, Uniformity : + 2°C
Humidity Range : 40% To 95% RH.
Resolution : 0.1%,Accuracy : + 2%, Uniformity : + 3%.
Validation :
Validation of Chambers (Temperature Mapping) will be done at different zones in the chamber using pre calibrated multi channel Scanner (4 Channels for Temperature & 4 Channels for RH). Mapping of the chamber ensures the uniform temperature & Humidity inside the chamber as per the ICH norms and there by to determine the Hot zone and Cold zones.
Illumination :
Photo stability chambers provide lights as per option 2 mentioned in ICH guidelines A cool white florescent light for 1,2 million LUX hours exposure. UV-A lights for 200 watt hours / square meter exposure. Both the lights have independent control to avoid over exposure. Chamber is illuminated using 4nos of flourescent tube light to produce visible light (measure in lux). A one no. Near UV light of wavelength 365nm ( measured in watt/sq. Meter) are fitted on topside of the chamber.
Air Circulation : [Laminar Type]
The chamber is provided with best air circulation to give better temperature uniformity this is achieved by using one set of motor & blower in baffle wall Compartment to push treated air in working chamber. This system gives better than 1 deg c. temperature uniformity in working chamber, evaporator, heaters & steam injection system is from back side, behind baffle wall, the air circulation blower is also fitted in this compartment only. This arrangement helps to mix steam and air together and pass well mixed air inside the working chamber. Due to above system the temperature and humidity (R.H.) in complete chamber almost remains equal.
