Drug Stability Test Chamber CN-1000SD Drug Strong Light Exposure TestIntended to investigate the stability of drugs under intense light conditions and evaluate whether light can cause quality issues such as degradation, discoloration, or decreased potency. This experiment usually places drug samples (without outer packaging or using transparent packaging) in a dedicated strong light irradiation box, which provides visible light with a total illumination of not less than 1.2 million lux (Lux) and near ultraviolet light (UV) with an energy of not less than 200 watt hours per square meter that exceeds conventional storage conditions, and strictly controls the temperature (such as 25 ° C) for 10 days of continuous irradiation.
During the experiment, samples will be taken and analyzed at designated time points (such as the 5th and 10th day). Compare the changes in key indicators of the sample before and after irradiation using precision instruments, such as appearance, active ingredient content, and the generation of related substances (degradation impurities). Ultimately, based on these data, the sensitivity of drugs to light can be determined, providing key scientific basis for determining whether light shielded or opaque packaging is necessary, as well as for establishing strict storage and usage conditions.
Drug Stability Test Chamber CN-1000SD Drug Strong Light Exposure TestMain features:
1. New fluorine free design, high efficiency, low energy consumption, and promotes energy conservation.
2. Adopting a special sterilized stainless steel inner liner, with a four corner semi-circular arc design, it is easy to clean and operate.
3. Microcomputer servo controller, digital temperature and humidity display.
4. LCD touch screen controller, all functions are displayed on the screen in the form of graphics and text, and the real-time running status is shown in the curve graph.
5. Continuous operation guarantee: Two fully enclosed compressor units automatically switch to ensure continuous operation of the equipment.
6. Continuous operation does not require defrosting, avoiding temperature and humidity fluctuations inside the box during use due to defrosting.
7. Adopting imported humidity sensors to avoid the troubles caused by frequent replacement of wet bands in traditional wet bulb sensors.
Security function:
1) When the box door is opened, the gentle breeze circulation and heating automatically stop, without the problem of temperature overshoot.
2) The speed of the circulating fan is automatically controlled to avoid sample evaporation caused by excessive wind speed.
3) It has a password lock screen function to avoid accidental operation by non experimental personnel.
4) The independent temperature limit alarm system can provide audible and visual alarms to alert the operator.
5) Temperature deviation alarm, compressor overheating, overload, overpressure protection, and water shortage protection.
