General description
Monodisperse polystyrene based micro particles (size: 3.0 μm) are a size standard, designed to identify the particle size distribution (PSD) profile of test samples.
Application
Used to validate and monitor the performance of particle sizing equipment.
Also used:
Also used:
- in acoustic traps to study the effect of non-contact retention of microparticles on trapping performance of lab on chip systems
- to synthesize microsphere-based interferometric optical probe called reflectophore
Features and Benefits
- suitable for routine instrument calibration checks and corrections
- available in 5 mL pack size as a neat sample
Analysis Note
For every lot exact values of particle size and standard deviation are determined with an accuracy of 0.001 μm. The size determination of these particles follows procedures described by National Institute of Standards and Technology (NIST, USA) respectively by the Community Bureau of Reference (BCR), esp.:
- Transmission electron microscopy (TEM)
- Scanning electron microscope
- Light microscopy
- Coulter™ counter with MDF-system

Fluorescent optical probes have rapidly transformed our understanding of complex biological systems by providing specific information on biological targets in the natural living state. However, their utility is often limited by insufficient brightness, photostability, and multiplexing capacity. Here, we report
