|
We are one of the leading manufacturers of chromatography adsorbents such as aluminum oxide and silica gel column. Our column chromatography has gained wide appreciation for simple packing procedure, low operating pressure and low expense for instrumentation. The smaller particles of silica gel are used for flash chromatography while larger particles are used for gravity chromatography. The silica gel is available in various grades ranging from 35-70 mesh to 400-800 mesh. Our chromatography adsorbents comprise :

We are engaged in the formulation of aluminum oxide chromatography that has both acidic and basic characteristics. White to off white, this fine-grained powder is highly porous form of aluminum oxide with surface more polar than that of silica gel. Reflecting the amphitrical nature of aluminum, the chromatographic characteristics are determined by its specific (internal) surface area measured by the BET Method, its mean pore diameter and its pore volume. We assure our clients of the reproducible chromatographic performance of our aluminum oxide. In the separation and purification of dyes, dye intermediates alkaloids, steroids, liquids, amino acids, hormones, aliphatic and aromatic hydrocarbons, vitamins Safety measures : - Storage Conditions: Store in a dry room
- Prevention against water, acid and alkalis

| Silica Gel Column Chromatography Silica gel column chromatography has found its place in many laboratories for reaction control in organic syntheses and preparative purposes. Column chromatography has gained wide appreciation for simple packing procedure, low operating pressure and low expense for instrumentation. Depending on flows of solvent down the column chromatography is separated into two categories : - Solvent flow down the column by gravity, or percolation, it is called gravity column chromatography
- Solvent is forced down the column by positive air pressure, it is called flash
- Chromatography Organic chemist use two common adsorbents silica gel (SiO2) and alumina (Al2O3) for column chromatography.
These adsorbents are sold in different mesh sizes, as indicated by a number on the bottle label. Adsorbent particle size affects how the solvent flows through the column. Smaller particles (higher mesh values) are used for flash chromatography; larger particles (lower mesh values) are used for gravity chromatography. For example, 70, 230 silica gels are used for gravity columns and 230, 400 mesh for flash columns. Grades Available : - 35-70 mesh
- 60-120 mesh
- 70-230 mesh
- 100-200 mesh
- 200-400 mesh
- 230-400 mesh

Aluminum Oxide Chromatography We assure to supply the highest quality chromatography sorbents, with controlled physical characteristics for reproducible chromatographic performance.
Aluminium Oxide for Chromatography is a white to off white, fine-grained powder, highly porous form of aluminum oxide. Its surface is more polar than that of silica gel and reflecting the amphitrical nature of aluminium, has both acidic and basic characteristics.
Applications Aluminium Oxide for chromatography is being used in the laboratory and in industrial production.
For Preparative column chromatographic separations, Isolation & Purifications of Antibiotics.
As a support material in analytical chromatographic columns
Purification & Dehydration of Organic Solvents
On industrial scale for the removal of small amounts of undesired components.
e.g. : Side reaction products from mother liquors, water from non-polar solvents, etc.
In the separation and purification of dyes, dye intermediates alkaloids, steroids, liquids, amino acids, hormones, aliphatic and aromatic hydrocarbons, vitamins.
For purification of Natural Products & herbals like Reserpene, Capsacin & some oleoresins.
Storage Conditions: Store in a dry room. Prevention against water, acid and alkalis.
