Pharmaceutical Stability Test Chamber from Jeiotech provides precise temperature, humidity, and light control for pharmaceutical stability and photostability testing. Designed to support ICH Q1A (R2) and ICH Q1B testing requirements, the system combines inverter refrigeration, PID control, and independent VIS and UV-A light sources. Its advanced monitoring and data management features support reliable testing and documentation. Apex Scientific supplies pharmaceutical stability test chambers throughout South Africa, providing laboratory equipment for pharmaceutical research, quality control, and stability studies.
Reliable temperature and humidity control
The pharmaceutical stability test chamber supports long-term stability testing in accordance with ICH Q1A (R2) guidelines. Its energy-efficient inverter refrigeration system works alongside PID control to maintain consistent temperature and humidity while reducing energy consumption.
Furthermore, the chamber maintains its specified temperature and humidity control range regardless of whether the lamps are switched on or off. This allows laboratories to conduct different stability studies without compromising environmental control.
The system also supports continuous operation without defrosting, including during long-term stability testing at 5°C. Consequently, laboratories can maintain uninterrupted testing conditions over extended periods.
Additionally, an optional recorder supports test documentation, while the inner glass door allows convenient sample observation and access.
Photostability testing according to ICH Q1B
The pharmaceutical stability test chamber supports photostability testing according to ICH Q1B Option 2. Independent VIS and UV-A light sources allow laboratories to control visible and ultraviolet exposure separately.
Integrated light sensors measure actual and accumulated exposure values, which the controller displays during testing. Furthermore, the system shows accumulated exposure time and the remaining time required to reach the selected exposure target.
Once each light source reaches its programmed exposure value, the automatic lamp-off function switches it off. As a result, laboratory personnel can manage photostability studies with greater control over light exposure.
Specially designed filters and an optimised lamp arrangement also promote uniform illumination across the chamber’s vertical testing area.
Uniform environmental conditions and efficient design
Jeiotech designed the pharmaceutical stability test chamber to maintain consistent conditions throughout the testing space.
Stable horizontal airflow promotes uniform temperature and humidity distribution, even when the chamber contains larger sample loads. Additionally, the external humidification system supports stable humidity control while keeping the internal chamber easier to clean and maintain.
High-quality insulation and a double-sealed door structure help minimise environmental fluctuations. Consequently, the equipment supports reproducible conditions during repeated stability studies.
The slim, space-efficient design also helps laboratories maximise available floor space without compromising functionality.
Advanced programming and calibration
The pharmaceutical stability test chamber offers both fixed-condition and programmable operation, allowing users to configure different testing protocols.
The controller supports 10 programs, 10 steps, and up to 99 repeat cycles. Furthermore, automatic temperature and humidity tuning helps maintain stable operating conditions.
A 16-zone PID control system provides additional precision, while calibration functions support temperature, humidity, VIS, and UV-A measurements.
The system also saves program information and backs up operating settings, helping laboratories maintain consistent test configurations.
Data management and remote monitoring
The pharmaceutical stability test chamber includes internal memory and USB storage for recording test data. Additionally, an RS-232 communication port comes standard, while RS-485 connectivity is available as an option.
Dedicated PC monitoring software allows users to control equipment, monitor operating conditions, and store data. The software supports connections to up to four chambers, simplifying laboratory monitoring.
For remote access, the optional LC Connected system enables mobile monitoring through the LC GreenBox interface.
Furthermore, Jeiotech offers optional LC DataKeeper software, which supports FDA 21 CFR Part 11-compliant electronic records and data integrity requirements. This functionality can assist pharmaceutical laboratories with documentation and GMP audit preparation.
