Descrizione

Descrizione generale

Polymethacrylate-based microparticles (size: 100 μm) are a size standard, ideal to determine the particle size distribution (PSD) profile of a particle system.

Applicazioni

Used to standardize and monitor particle size instruments.
Also used to calibrate complex refractive index (CRI) of known PMMA microspheres.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Caratteristiche e vantaggi

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

Risultati analitici

The exact values for particle size and standard deviation are determined for each lot and may be found on the certificate of analysis. These values are determined with an accuracy of 0.01 μm (Coulter Multisizer). Polymethacrylate based particles have a narrow size distribution and spherical shape. They are stable at temperatures of up to 100 °C Density is 1.22 g/cm³. The surface is negatively charged. Good biocompatibility and reduced nonspecific protein binding are characteristic.
