SiliaFlash® - Irregular Silica Gels for Chromatography

SiliaFlash irregular silica gels

With pore diameters ranging from 30 to 1,000 Ångström (Å) and particle sizes up to 1,200 μm, SiliCycle offers products to meet all your requirements.

We offer one of the most reliable portfolios for flash and gravity grades for low to medium-high pressure. Our silica gels are ideal for preparative chromatography, from laboratory to pilot-plant processes and production scale. In addition to performance, SiliCycle’s silica gels also ensure consistency, reliability and reproducibility.

 

Ensure Unbeatable Chromatography Performance

  • High purity silica with the lowest level of fines on the market
    No contamination, lower back-pressure and superior separation
  • Exceptional narrow particle and pore size distributions
    Optimal separation and resolution
  • Batch-to-batch, year-to-year consistency
    Reliable chromatography
  • Neutral pH
    Wide range of products can be purified, even acid sensitive ones
  • Low metal content & controlled water content
    Symmetrical peaks without tailing
  • High mechanical stability
    Can be used under high pressures without surface abrasion
  • High surface area and density
    Greater loading capacity, enabling more silica for the same volume.
    Solvent economy (smaller dead volume)
  • Availability in bulk quantities
    Always in stock with on-time delivery

 

Different grades available for our most popular products

Over the years, SiliCycle has developed two different grades for the two most popular irregular gels used in the industry:

  • 40 - 63 μm, 60 Å
  • 60 - 200 μm, 60 Å

Those two grades of each gel are available to address all of our customers’ requirements, depending on their applications, areas of research, budgets and so on.

2 grades of 40 - 63 μm, 60 Å silica gels
Grade Superior Grade Standard Grade
Name F60 (PN: R10030B) P60 (PN: R12030B)
Particularities
  • Extra step to reduce metal content to minimum level
  • Tighter particle size distribution
  • Fines have been removed
  • Fines have been removed
  • Lower price

Both compare favorably with the overall industry average of a 40 - 63 μm distribution, and each grade offers its own particle size distribution profile.

2 grades of 60 - 200 μm, 60 Å silica gels
Grade Superior Grade Standard Grade
Name G60 (PN: R10040B) GE60 (PN: R10140B)
Particularities
  • Extra step to reduce metal content to minimum level
  • Tighter particle size distribution
  • Fines have been reduced to minimal level
  • Fines have been reduced to minimal level
  • Lower price

Each grade offers its own particle size distribution profile.
