Photostability Chamber Manufacturer in India: Ensuring Light-Stress Testing with Precision
In pharmaceutical, cosmetic, chemical and material industries, stability under light exposure is a critical parameter. Photostability chambers simulate controlled UV and visible light conditions so you can test how your product degrades or changes over time. In India, with stricter regulatory norms and rising global competition, the demand for high-quality photostability chambers is increasing. Choosing a dependable manufacturer ensures your tests are valid, reproducible, and compliant.What Is a Photostability Chamber & Why It Matters
A photostability chamber (also called a “photo stability chamber”) is a specialized environmental testing enclosure designed to subject samples to controlled light (UV and visible) exposure along with defined temperature and humidity conditions.
These chambers are vital for:
- Stability testing of pharmaceuticals to evaluate how APIs, formulations, and excipients respond to light, as per ICH Q1B guidelines.
- Testing cosmetics and personal care products for color changes and degradation under light.
- Studying photodegradation of polymers, dyes, and packaging materials in chemical and material research.
- Meeting regulatory requirements where agencies such as FDA, EMA, and CDSCO demand photostability data for product approval.
Without a well-designed photostability chamber, test results may be inconsistent, increasing the risk of regulatory setbacks.
Features That Define a Robust Photostability Chamber
A reliable photostability chamber should provide complete control over light, temperature, and humidity. The chamber must be able to regulate UV and visible light intensity so exposure meets required thresholds, such as 1.2 million lux hours and 200 $Wh/m^2$ UV, as per ICH Q1B. Light distribution also needs to be uniform across the chamber to avoid hot spots that could affect some samples differently from others.
Temperature and humidity must remain consistent even when light sources generate heat, which is why precise controllers and uniform airflow are essential. Construction also matters—a chamber with stainless steel interiors, properly sealed seams, and durable design ensures long-term reliability.
Safety mechanisms like temperature and humidity deviation alarms, power failure alerts, and door-open warnings provide additional protection. For regulatory compliance, the ability to log data on light intensity, temperature, and humidity, along with USB or Ethernet connectivity for audits, is also a key feature. Many advanced models also support optional add-ons such as 21 CFR Part 11–compliant software, standby cooling or humidity systems, and GSM-based remote alerts.
Why India Is Emerging as a Competitive Base for Photostability Chambers
India has become a strong base for photostability chamber manufacturing due to several reasons. Pharmaceutical and cosmetic exports are growing rapidly, which has created higher demand for compliance-grade equipment. Indian manufacturers offer chambers that meet global standards at a competitive price point, providing better cost–value balance compared to imported units.
Local support is another major advantage—service, calibration, and spare parts are easier to access from a domestic supplier. Manufacturers in India also offer flexibility in customization, tailoring chambers to specific size or performance requirements. This flexibility is seen across the board, from small bench-top units to equipment from a large-scale Walk in stability chamber manufacturer in India. With ongoing innovation and better regulatory awareness, India is now a competitive and reliable hub for photostability chambers.
What Kesar Control Systems Offers in Photostability Chambers
As a leading Humidity chamber manufacturer in India, Kesar Control Systems applies its broad expertise in environmental control to design photostability chambers that combine durability, precision, and compliance. The chambers are fabricated using CNC automation for accuracy, with stainless steel interiors that are easy to clean and reflect light effectively. The outer body is either GMP-grade stainless steel or powder-coated GI, depending on the model, and the entire chamber is sealed with arc-welded seams for water- and vapor-tight performance.
The double-door system includes an insulated outer door and an inner glass door, providing both visibility and stability. Mounted on castor wheels for mobility, the chamber also comes with adjustable stainless steel trays for flexible sample placement.
For light control, the chambers use fluorescent tubes to simulate daylight and UV tubes to meet ICH testing requirements. Both UV and visible light can be adjusted and controlled automatically. Along with light, the system ensures stable temperature and humidity conditions through uniform air circulation and humidity generators.
The control system is PLC-based with a 7-inch HMI touch display for programming and monitoring. High-precision sensors provide accurate readings, while auto-tuning functions ensure minimal fluctuations. Data logging is available via USB and Ethernet, supporting audit requirements and remote monitoring.
Safety features include alarms for high or low temperature, humidity deviation, door open conditions, and low water levels. Optional features such as standby cooling, backup humidity systems, GSM alerts, and 21 CFR Part 11–compliant software make the chambers suitable for regulated industries.
The chambers are available in multiple models, starting from 227 liters up to larger capacities, with specifications such as a temperature range of 20 °C to 60 °C, accuracy of $pm$1.0 °C, and uniformity of $pm$2.0 °C. These specifications align with international photostability testing requirements.
Tips for Selecting a Photostability Chamber
When choosing a Photostability chamber manufacturer in India, it is important to confirm whether their units have validated performance data for light uniformity and UV intensity. Regulatory features like audit trail support and calibration certificates are also critical. Capacity should match your current needs but leave space for expansion, and strong after-sales service should be part of the package. Flexibility for upgrades, such as additional trays, remote monitoring, or compliance software, will also make the chamber more future-ready.
Conclusion
Photostability testing under controlled light is indispensable in industries such as pharmaceuticals, cosmetics, and materials research. With India’s growing reputation as a reliable base for environmental testing equipment, businesses can now access advanced chambers locally without compromising on quality.
