Provide greater durability and chemical stability when using solvents with Thermo Scientific™ 8000 Series Silica Particle Size Standards, monodisperse silica microspheres used in instrument calibration and as spacers. Standards are calibrated and certified with NIST™ traceable mean diameters and are suitable for a wide variety of particle measurement applications.
- Standards are designed for applications requiring monodisperse inorganic spheres.
- Opaque spheres provide more contrast than polymer particles in optical and electron beams; like glass, silica has a much higher density that polystyrene.
|Designed for applications requiring monodisperse inorganic spheres, the 8000 Series Silica Particles have a much higher density then the polymer particles.|
