Product Name: Superparamagnetic Carboxyl/Amino/Toluenesulfonyl/Sulfonic Acid Group/Polystyrene Silica Magnetic Beads
Product Introduction: Compared with MagnoMind magnetic microspheres, these magnetic microspheres have a higher content of magnetic material and a significantly improved magnetic response speed, which can accelerate the separation speed and improve the experimental efficiency. They are also suitable for high-viscosity systems. They exhibit excellent suspension stability in the aqueous phase and can adapt to a wide range of pH values and different buffer solution systems. In addition, MagnoSpeed magnetic microspheres have a smaller particle size and can be applied to the extraction and purification of small molecules.
Parameters:
- Microsphere particle size: 100 nm - 500 nm
- Functional groups: Carboxyl group, amino group, toluenesulfonyl group, sulfonic acid group, etc.
- Packaging specifications: 5 - 100 ml
- Solid content: 10% (100 mg/mL)
- Dispersant medium: Water
- Shelf life: See the bottle label
Characteristics:
- Superparamagnetic, with no residual magnetism after the external magnetic field is removed
- Stronger magnetic responsiveness, enabling rapid magnetic separation and application in high-viscosity systems
- Larger specific surface area for higher reaction efficiency
- Dense shell coating with no risk of magnetic particle exposure
- Uniform particle size, allowing simultaneous magnetic separation within a short time
- Stability: Can be stably dispersed in the pH range of 1 - 13 (Note: Prolonged exposure to an overly acidic environment may lead to the acid hydrolysis of magnetic particles due to the penetration of hydrogen ions into the microspheres). Without an external magnetic field, they can remain stably suspended for a long time, greatly improving the reaction efficiency.
