Silica Products for Organic Chemistry

The best quality silica for world leading products and reagents!

 

 

SiliaFlash® & SiliaBond® Bulk & Loose Silica

Very high purity acid washed silica gel with an industry leading particle size specification giving excellent reproducibility & unrivalled performance every time! Available from gram to multi-tonne scale.

More particles in the nominal range (90% compared to 80% for most competitors) - ensuring faster flow through the column and more efficient collection (lower fraction volume)

Low trace metal content / Neutral pH / Stable Water Content / High surface area of the material all ensure excellent reproducibility & unrivalled performance every time!


  SiliaSep® Flash LC Cartridges

Use the superior performance of the UltraPure SiliaFlash® and SiliaBond® silica gels in all your separations with the SiliCycle® SiliaSepT cartridges.

SiliaBond® Reagents and Metal Scavengers

Metal Scavenging / TFA Removal / Catch and Release
Reagents / Amide Synthesis

Functionalised silica products give a host of advantages over polymer scavengers including Faster Kinetics / No Swelling / Mechanically and Thermally stable / Excellent Facile Processing Attributes and Controlled Loading for good reproducibility.

Advantages over solution phase synthesis

  • Simpler purification process - no need for chromatography, liquid-liquid extraction, or crystallization
  • Multiple transformations in a single pot
  • Immobilisation of toxic reagents
  • Increased selectivity
  • Suitable for use in batch reactions and in flow through applications
