Thermo Scientific™ 4000 Series Monosized Particles

Description

• Minimize response of analytic systems to shape effects with Thermo Scientific™ 4000 Series Monosized Particles, excellent for use with any application that requires a NIST™ traceable size standard with a very narrow standard deviation
• Features: Particle spheres are used instead of irregularly shaped particles
• Mean diameters have been calibrated with Thermo Fisher Scientific™'s NIST™ traceable microscopy methods
• Size distribution and uniformity are measured by electrical resistance analysis or optical microscopy
• 4000 Series particles from 1 to 160μm are made from polystyrene (PS) 4000 Series particles from 200 to 1000μm are made from polystyrene crosslinked with divinylbenzene (PSDVB)
• Ordering Information: Products from 1 to 160μm are packaged as aqueous suspensions in 15mL dropper-tipped bottles, at an optimum concentration for dispersion, handling and dilution
• Diameters of 200μm and larger are packaged as dry spheres
• Packages are lot-numbered for convenient technical service and support after the sale
• Thermo Fisher Scientific™ has its own engineering, production and metrology facilities for better quality control and response to customer needs
• In addition to this line of polymer size standards, we also offer calibration standards in silica and glass materials
• Ask our technical service department for information about specific applications or other product needs not listed here
• Includes: Certificate of Calibration and Traceability to NIST, which includes a description of the calibration method and its uncertainty; Table of chemical and physical properties; Material Safety Data Sheet
