| Description

Scope of application:

A pharmaceutical stability testing chamber is a specialized piece of equipment designed to precisely control temperature and humidity, simulating real-world storage and transportation conditions for pharmaceuticals. It’s tailored specifically for pharmaceutical companies, biotechnology institutions, and research organizations. Its primary applications include assessing drug stability (through accelerated, long-term, and photostability studies), determining shelf life (by predicting drug degradation timelines under simulated temperature, humidity, and light conditions), and supporting quality control efforts—such as optimizing packaging and storage strategies. The chamber meets stringent international standards like GMP, FDA, and ICH, while also providing critical scientific insights for new drug development and material durability testing (e.g., in cosmetics and food packaging).

Structural features:

Outer Enclosure: The enclosure is crafted from high-quality cold-rolled steel sheet, finished with an electrostatic powder-coating process that creates a dense protective layer on the surface, ensuring durability, strength, and exceptional rust resistance.

The exterior door is equipped with a safety lock.

On the left side, a standard 25mm test hole is provided.

Workshop: The inner liner is made of SUS304 stainless steel with a mirror-polished finish. The shelf brackets feature a quick-release design for easy assembly and disassembly.

Built-in UV sterilization (sterilization time adjustable).

Observe the glass: The double-door design features tempered glass as the inner observation panel, allowing direct access to open the outer door for monitoring the culture conditions inside the chamber. Its excellent sealing performance ensures that the internal temperature remains unaffected.

Ventilation System: A robust, cross-flow ventilation structure that creates an efficient air circulation system, enhancing temperature response speed while improving temperature uniformity and minimizing thermal fluctuations.

Control Panel: Featuring a microcomputer-based smart touch-screen temperature controller with high precision, zero overshoot, and multi-data display on a single screen. It includes temperature correction and timing functions, allowing users to set up to 30 program segments with cycle durations ranging from 0 to 9,999 cycles. Additionally, the panel offers remote alarm and remote control capabilities, along with a built-in USB interface for real-time data storage.

Standard equipment includes a miniature needle printer.

Refrigeration System: Dual-compressor cooling system—featuring one unit as a backup and the other in active use, or alternating operation—to effectively extend service life and ensure stable equipment performance. (Note: Models with 280 liters or larger capacity are equipped accordingly.)

Humidification System: Equipped with a top-brand humidity sensor and featuring built-in humidification technology, this system utilizes a 316 stainless steel humidification tube to generate steam via heating, ensuring precise humidity control with minimal internal fluctuations and excellent uniformity. Additionally, it comes with an external 25L water tank that provides up to 15–20 days of operation on a single fill.

Standard Pharmacopoeia: This product meets the relevant requirements outlined in GMP, FDA, ICH, and national pharmacopoeias.

Safety Systems: Inner chamber temperature protection, compressor overcurrent protection, compressor overpressure protection, low-water protection, heater overheating protection, audible and visual alarm upon fault detection, and auxiliary temperature controller.
