PSC-GP Series

Pharmaceutical Stability Test Chamber

 

0~65℃ (Illumination range: 15–50°C) | No Humidity Control

图片4.png

LAB1ST PSC-GP Series is a specialized pharmaceutical stability test chamber designed for strong light exposure testing under controlled temperature conditions (0–65°C, with illumination active between 15–50°C). 

 

It delivers reliable performance for photostability testing of pharmaceuticals, packaging materials, raw substances, etc.
