Scope of Application:
The Comprehensive Drug Stability Test Chamber simulates drug storage and transportation environments by precisely controlling temperature, humidity, and light. It is designed for pharmaceutical companies, biotechnology institutions, and scientific research units. Its applications include drug stability assessment (accelerated, long-term, and strong light irradiation testing), shelf-life determination, and quality control (packaging and storage optimization). It meets international standards like GMP, FDA, and ICH, and supports new drug development and material weather resistance testing (e.g., cosmetics, food packaging).
Structural Features:
Outer Casing: Constructed from cold-rolled steel plate with electrostatic baking paint, forming a dense, robust, and rust-resistant protective layer. Includes a standard 25mm test port and a safety lock on the outer door.
Working Chamber: Features a mirror-polished SUS304 stainless steel interior with quick-release shelf brackets for easy installation and removal. Equipped with built-in UV sterilization (time-adjustable).
Viewing Glass: Double-door design with a tempered inner glass, allowing direct outer door opening for observation without affecting internal temperature due to effective sealing.
Air Flow: Strong convection ventilation ensures efficient air circulation, improving temperature response, uniformity, and reducing fluctuation.
Control Panel: Microcomputer-based intelligent touch screen controller offers high precision, no overshoot, multi-data display, temperature calibration, timer, and program control (0-30 segments, 0-9999 cycles). Includes remote alarm/control, USB interface for real-time data storage, and a standard miniature needle printer.
Refrigeration System: Dual compressor system (backup or alternating use) enhances service life and ensures stable operation (standard for 280L+ models).
Light Source: Cold light sources minimize heat, stabilizing internal temperature. Top-mounted vertical lighting with two panels ensures uniform distribution. Adjustable intensity (red/blue/white/plant growth lights available).
UV System: Real-time UV meter display meets requirements for near-UV energy ≥200 W·hr/m² (per chemical drug stability guidelines). UV irradiance: 80~100 μW/cm²; spectrum range: 320~400 nm.
Humidification System: Uses first-tier humidity sensors with internal humidification technology (Type 316 tube for steam generation), ensuring low humidity fluctuation and good uniformity. External 25L tank lasts 15-20 days per fill.
Pharmacopoeia Standards:Complies with GMP, FDA, ICH, and National Pharmacopoeia requirements.
Safety System: Includes inner chamber temperature protection, compressor over-current/over-pressure protection, water shortage protection, heater over-temperature protection, audible/visual alarms, and auxiliary temperature control.
