Blue silica gel consists of blue or light blue glassy particles. The product is available as blue silica gel indicator and blue silica gel. It exhibits hygroscopic properties, changing from blue to purple and eventually to light pink as it absorbs moisture. This color change indicates the humidity level of the environment and signals when a replacement desiccant is needed. Blue silica gel can be used independently as a desiccant or in conjunction with Type A Silica Gel.
Blue silica gel is primarily used for absorbing moisture and preventing rust in instruments, gauges, and equipment kept in enclosed conditions. As it absorbs moisture, it transitions from blue to red, visually indicating the relative humidity of the environment. When used alongside ordinary silica gel or a drier, it helps gauge the moisture absorption level and determine the relative humidity of the surroundings. This versatile product is commonly employed as a silica gel drier for packaging precision instruments, leather goods, shoes, clothing, food items, medications, and household appliances.

Column chromatography silica gel is a white uniform powder particles, non-toxic, and tasteless. The main component is silica, known for its high purity, safety, and health benefits. Due to its different adsorption residence time for various substance components, it enables the separation and purification of mixed components effectively.
Primarily used for refining petroleum products by removing aromatic substances or for separating and purifying the active components of Chinese herbal medicine. It is also ideal for the preparation of high-purity substances.
