General description

Rhodamine B-labeled, melamine resin-based microparticles (size: 10 μm) are a particle size standard, ideal to determine the particle size distribution (PSD) of test samples.

Application

Used for equipment particle size calibration with fluorescence detection.
Also used in:
  • fluorescence imaging applications
  • optical sectioning studies of high-and-low-frequency (HiLo) microscope

Features and Benefits

  • suitable for routine instrument calibration checks and corrections
  • delivered in 5 mL and 10 mL pack sizes as neat samples

Analysis Note

For every lot, exact values of particle size and standard deviation are determined with an accuracy of 0.01 μm using a Coulter Multisizer.
