Description

Replace polystyrene spheres in many applications with Thermo Scientific™ 9000 Series Glass Particle Standards, dry glass NIST™-traceable size standards. Glass microspheres can be used in any application that requires a NIST™-traceable size standard with a narrow size distribution where sample conditions may not be suitable for polystyrene spheres. The glass microspheres provide a better tolerance to chemicals and solvents in addition to higher mechanical and thermal stability.

• Mean diameters have been calibrated with Thermo Fisher Scientific™'s NIST™-traceable microscopy methods
• Size distribution and uniformity are measured by optical microscopy
• Spheres are used instead of irregularly shaped particles to minimize the response of analytical systems to shape effects
• Products are packaged as dry spheres
• Packages are lot-numbered for convenient technical service and support after the sale
• 9000 Series products from 2μm to 20μm are made from borosilicate glass, have a particle density of 2.5 to 2.55g/cm3 and an index of refraction of 1.56 at 589nm (25°C)
• Products from 30μm to 2000μm are made from soda lime glass, have a particle density of 2.4 to 2.5g/cm3 and an index of refraction of 1.51 at 589nm (25°C)

Includes:

Certificate of Calibration and Traceability to NIST™, including description of the calibration method and its uncertainty, table of chemical and physical properties, and Material Safety Data Sheet with handling and disposal instructions.

Recommended for:

Spacer applications where uniform bond thickness is a necessity.
