General description
作为实验室常用的干燥剂，变色硅胶（或称硅胶橙）适用于所有气体和固体的干燥。它可用于干燥塔、干燥器和吸收管。由于其巨大的表面积，硅胶橙具有良好的吸附能力，可用于长期储存。当其吸收水分时，它由橙色变为无色。（负载量大约6 wt %）
Application
Silica Gel with Orange gel indicator can be used for:
- Moisture Management: Commonly found in desiccators, it protects hygroscopic chemicals and solids from moisture, ensuring sensitive materials stay intact during storage and experimentation.
- Chromatographic Adsorption: Serves as a stationary phase in chromatography, aiding in the effective separation and analysis of various chemical compounds.
- Equipment Protection: In laboratory settings, it absorbs excess humidity to prevent corrosion and damage to sensitive equipment, extending the lifespan of valuable instruments.
- Drying Agent for Gases and Liquids: Utilized in drying towers and absorption tubes, it efficiently removes moisture from gases and liquids, improving the accuracy of analytical results.
