Kesar Control
Photostability Chamber
Introduction
Kesar Control Systems, a leading pharmaceutical and scientific equipment manufacturer, offers Photostability Chambers designed for controlled light and temperature testing of pharmaceutical, cosmetic, and industrial products. These chambers ensure compliance with ICH Q1B guidelines, making them essential for stability testing under simulated daylight conditions.
A Photostability Chamber is a specialized environmental chamber used to test the effects of UV and visible light exposure on pharmaceutical formulations, food products, cosmetics, and packaging materials. By simulating natural and artificial light conditions, these chambers help manufacturers assess the stability, degradation, and shelf life of products exposed to prolonged illumination.
Kesar Control Systems' Photostability Chambers provide precise temperature, humidity, and light control, ensuring accurate and repeatable results for regulatory compliance and quality assurance.
Construction
- The exterior body is fabricated from powder-coated mild steel or stainless steel, offering durability and corrosion resistance for long-term reliability.
- The inner chamber is made of high-grade stainless steel (SS 304/SS 316), ensuring a contamination-free environment with a smooth, easy-to-clean surface.
- A double-walled construction with high-grade rock wool insulation minimizes heat loss and maintains stable internal conditions for precise testing.
- A tempered glass viewing window with UV protection allows safe observation of samples without disrupting the controlled testing environment.
- An insulated door with a magnetic gasket ensures an airtight seal, preventing temperature fluctuations and maintaining controlled conditions.
- The door is equipped with a secure latch mechanism and a silicone gasket, ensuring a tight seal at all operational levels.
- Adjustable perforated stainless steel shelves allow flexible sample arrangement, optimizing space utilization within the chamber.
