PARTICLE SIZE STANDARDS and MICROSPHERES (Duke Scientific / Thermo Scientific)

• Certified Particle Size Standards – Wide range of narrowly distributed sizes from 20nm to 2000µm in glass, polymer and silica.
  
  
• Standards for Particle Counting Methods – Certified size standards and count controls for instrument calibration, validation etc
  
  
• General Purpose Microspheres and Particles – Economical polymer and glass microspheres with well defined sizes. Also metal and mineral particles and a range of spherical pollens and spores.
  
  
• Fluorescent Microspheres – Red, blue and green fluorescent particles from 30nm to 10µm and green microspheres in dry form, 6-165µm diameter
  
  
• Reagent Microspheres – Plain or fluorescent microspheres with controlled surface chemistry for diagnostic test development and bioscience applications
  
  
• Microspheres For Flow Cytometry – Cyto-Plex carboxylated microspheres for Suspension Array Analysis and Cyto-Cal calibrator beads and kits
  
  
• Particles for Special Applications – HEPA filter testing and smoke detector challenge particles, SURF-CAL particle deposition standards for semiconductor applications.
