Blue Silica Gel for Column Chromatography

Blue Silica GelBlue silica gel includes blue indicating silica gelcolor-changing silica gel and blue silica gel. Blue silica gel has the appearance of the blue or light blue glass-like particles, according to the shape of particles It can be divided into spherical ones and block ones. Meanwhile, It has a property of turning pink from blue after absorption.Use
Mainly used for moisture absorption and rust proofing when instruments and equipment are placed in obturation conditions, at the same time, according to their own color turning red from blue after the moisture absorption it can indicates ambient humidity directly.
It being used with ordinary desiccant silica gel, we can get the desiccant moisture level and judge the relative ambient humidity.
Desiccant silica gel used for packaging, it is widely used in precise instruments, leather, shoes, clothing, food, medicine and household appliances, etc.Size
