Sera-Mag Magnetic Particles

 

Manufactured by Seradyn
   

 

The Sera-Mag range of magnetic microparticles are based on patented 1mm magnetic carboxylate modified base particles manufactured by a core-shell process. The surface has a unique cauliflower-like structure with a high carboxylic acid content ensuring a high binding capacity and fast reaction kinetics. Sera-Mag microparticles are colloidally stable in the absence of a magnetic field, however when a magnetic force is applied the particles are separated rapidly and completely from suspensions.
