Hollow Silica Particles

Glantreo’s  magnetic particles are the product of many years working with silica particles and chemistries as well as the desire to deliver the superior quality products for bio-analysis and separations. These particles available in 2 different particle sizes (400nm and 1000nm) can be supplied as unfunctionalized, Amine functionalised, carboxyl functionalised and protein A functionalised.

The particles are supplied in aqueous format.  The particles themselves are monodispersed magnetite particles coated with a thin layer of silica that allows functionalisation with amine and  carboxyl groups as well as functionalisation with protein A.  The particle size of 0.5-1um produced the optimal size for attaching bop molecule for research, purification, and samples preparation studies.  Glantreos magnetic beaded are completely spherical unlike other magnetic beads and the smooth surface eliminate the carryover carryover of impurities common to rough-surfaced beads.  Because the silica magnetic beads are spherical and uniform, DNA/RNA or protein purification can be performed with outstanding efficiency and reproducibility.

High magnetization (60 emu/g) and strong binding capacity giving fast magnetic response (~5 secs) and shorten time required for magnetic steps during isolation.  The magnetic property of the bead allows an external magnetic field to be applied for quick separation.  Our magnetic beads remain well suspended and dispersed for over 60 mins providing good handling and suitability for automation.  Glantreo has been producing quality nanomaterial for 10 years in an ISO 9001 certified operation.  Technical support is always at hand and a quick delivery of your order is assured.
