Metal Scavengers and Organic Scavengers – SiliaMetS® & SiliaBond®

SiliCycle is a pioneer in metal and organic scavenging solutions. We have nearly two decades of know-how in silica-grafting and scavenging technologies, and the broadest portfolio of scavengers.

The removal of post-reaction residues has become a major issue in the pharmaceutical industry, among others. Purification of APIs by traditional methods (chromatography, activated carbon, distillation, etc.) often leads to problems such as high costs, time loss, low efficiency and reduced final yields.

To overcome these drawbacks, SiliCycle has developed two families of scavengers that have significantly improved how chemists purify APIs: SiliaMetS Metal Scavengers and SiliaBond Organic Scavengers. The backbone of all those products is SiliCycle SiliaFlash® F60 (40-63 µm, 60 Å) which provides superior performance for all types of applications, due to its narrow particle size distribution and exceptional purity. What's more, we can provide different particle sizes or pore diameters on a custom basis.

SiliCycle’s quality is famous and recognized, proven by countless applications and patents in literature. With our strong, extensive and confidential team of experts, your projects are in the best possible hands.
