Flash Spherical Silica Gel

Flash spherical silica gel is ideal for column chromatography, process scale LC, and batch adsorption applications.

The abundant silanol groups on the surface are readily accessible for hydrophilic interactions with more polar compounds which generally are retained longer, making them ideally suited for the purification of chemical synthesis intermediates, oils, fats and natural products (vitamins, flavors, fragrances, etc.)

Flash spherical silica gel is available in porosities of 70Å, 100Å, 300Å, and 500Å and a particle size distribution of 40-75µm.

Quality and diversity

Flash spherical silica gel utilizes Sorbtech’s Premium Rf™  Silica Gel which boasts narrow pore and particle distributions, ensuring optimal selectivity, capacity, efficiency, low operating pressure, and shorter processing time.

Purity

Premium Rf Spherical Silica Gel is manufactured to a high chemical purity standard (99.9% SiO2). Organics and trace metals content are controlled within very stringent limits. Each production batch has undergone extensive and exhaustive quality control testing to ensure reliable lot-to-lot performance. This rigid control of chemical purity, surface area, and pore size, ensure our silica will yield reproducible separation results and allow for direct scale-up without requiring time-consuming method redevelopment.

Robust

Our flash spherical silica gel is mechanically robust and can, therefore, be repacked multiple times in either analytical or preparative scale columns.

Spherical Silica Gel - Premium Rf Advantages
Features Benefits
Narrow particle size distribution
  • Higher (Sharper) resolution
  • More reliable resolution
Minimal fines
 This means the backpressure is lower and faster run time.
Uniform porosity
 High loading – which means you can load up to 30% more than granular – which means you can do fewer runs.
Minimal small pores
 Lower risk of trapped solute in pores – which means you don’t lose your expensive sample.
Small pore volume
  • High bulk density – which means more silica in the same column – which leads to higher loading.
  • Lower “dead” volume – which means less solvent use.
Low metal content
 Low interference of analytes (High Purity - 99.9% SiO2) and (individual metal content < 300 ppm) – which means you won’t have peak tailing with certain types of molecules.
Mechanically stable spheres
  • Stable rigid bed – which means the column bed won’t collapse, and you won’t have to replace the column so often.
  • Significantly less fine particle generation – which means the backpressure won’t gradually increase until the column is unusable.
