Explosion-proof pharmaceutical stability testing chambers are primarily employed within pharmaceutical enterprises, drug research and development, vaccine development, and cosmeceutical research sectors. Depending on the testing objectives, they provide essential equipment for conducting accelerated testing, long-term testing, high-temperature and high-humidity testing, intense light exposure testing, and comprehensive testing on pharmaceuticals, vaccines, cosmeceuticals, and other products.
1. The product complies with IIB explosion-proof standards and is suitable for hazardous locations with explosive gas mixtures in temperature classes T1 to T4. It achieves an explosion-proof rating of IIB T4. The product has been certified as compliant by the ****** Electrical Safety Quality Inspection and Testing Centre and holds a valid ********* explosion-proof certification;
2. The electrical control system employs a composite explosion-proof technology combining flameproof and encapsulated designs. The operational switch is a passive switch, generating no mechanical sparks during operation for safe and reliable use. Sensors are equipped with external safety barriers for explosion-proof isolation;
3. Core components (refrigeration cycle) feature imported compressors and circulation fans. The compressor employs encapsulated explosion-proof technology for safety and reliability. Utilising fluorine-free, environmentally friendly refrigerant, it fosters a healthy laboratory environment;
4. The internal air circulation system employs high-temperature resistant, low-noise explosion-proof axial fans for forced circulation. The refrigeration system's classic configuration has demonstrated stability through years of market validation, ensuring safety and reliability;
5. Microcomputer intelligent temperature control system with large LCD screen/7-inch touchscreen (optional), featuring PID logic operation for manual PID control and PID self-tuning functionality;
6. Program capacity: 100 sets, 1000 segments, 999 cycle steps. Maximum time setting per segment: 99 hours 59 minutes, accommodating virtually any experimental procedure;
7. Employs internationally favoured internal humidification, offering superior temperature stability compared to external humidification. International brand humidity sensors deliver precision matching advanced global standards;
8. Automatically saves parameters during unexpected events with power-restoration capability, alongside sensor self-diagnosis, over-temperature, and fault alarm functions;
9. Inner chamber constructed from 304 stainless steel; outer casing from premium cold-rolled steel plate with electrostatic powder coating for durable, rust-resistant finish;
10. Oversized observation window with double-glazed tempered glass for clear visibility and precise control throughout experiments;
11. Magnetic seal door for effortless opening and superior sealing; Adjustable shelves optimise space utilisation;
12. Ergonomic design includes standard interior lighting and test ports to accommodate diverse experimental requirements;
13. IQ (Installation Qualification), OQ (Operational Qualification), and PQ (Performance Qualification) services available to ensure compliance with performance specifications (additional charge);
15. Third-party calibration reports provided upon request (additional charge).
