Our Premium Rf silica gel is the highest-purity granular silica gel on the market.

Premium Rf provides narrow particle and pore distributions and is engineered to increase yield, making it ideal for complicated separations both in the lab and in full-scale production.

• Purity: 99.95% SiO₂
  • This is our highest purity with very low metal impurities. This ensures maximum resolution without tailing peaks as compared to our competitors.
• Tighter particle distribution: 40-75µm ± 5% vs leading brands ± 10-12%
  • Better and easier packing
  • Reduced channeling in the bed, leading to tighter bands, thus better separation
  • Lower pressure drop due to fewer fines. This leads to faster flow and reduced
    run times.
• Controlled particle shape and effective surface area
  • This leads to improved peak symmetry
  • Greater reproducibility from batch-to-batch

• Tighter pore size distribution: minimum small pores
  • Maximum targeted surface area available, leading to greater loadability
  • Minimum risk of product trapped in pores, leading to a longer lifetime of the silica gel

• Side by side comparison tests of every major silica gel show our Premium Rf to give the best results
  • Easier to pack
  • Faster run time
  • More fractions, more cycles
  • Better resolution
