Colloidal Sillica
    Sillica Gel
    What is a Sillica Gel
Types of Sil-Po Silica Gel:
Sil-Po Chemical is manufacturing three types of Sil-Po Silica Gel which are given below:
Sil-Po Indicating Silica Gel
Sil-Po Non-Indicating Silica Gel
Sil-Po Chromatography Silica Gel
What is Sil-Po Indicating Silica Gel?
Sil-Po Indicating Silica Gel is solid with grainy porous structure free from extraneous imparities and its color is Blue. The Sil-Po indicating Silica Gel is impregnated with Cobalt Chloride.
What is Sil-Po Non-Indicating Silica Gel?
Sil-Po Non-Indicating Silica Gel is White, solid with grainy porous structure free from extraneous imparities.
General Properties of Sil-Po Silica Gel (Indicating & Non-Indicating)

What is Sil-Po Chromatography Silica Gel?
Sil-Po Chromatography Silica Gel is powder form based on the scientific patent and manufacturing litratare as per it’s specification 12008-1986. Chromatographic grade Silica Gel is mainly used for analytical purpose in thin layer Chromatography high performance liquid Chromatography and partition column Chromatography.
Sil-Po Chromatography Silica Gel has two grades:
for thin layer Chromatography
for partition column Chromatography
Sil-Po Chromatography Silica Gel Grade 1 has two types:
Silica Gel without binder
Silica Gel with binder
