Popis

General description

Polymethacrylate-based microparticles (size: 60 μm) are an analytical standard, ideal for profiling particle size distribution (PSD) of test samples.

Application

Used for validation and monitoring of particle sizing instruments.
This particle size standard is also used to detect, count and differentiate microscale particles.

Features and Benefits

• suitable for routine instrument calibration checks and corrections
• available in 5 mL pack size as a neat sample

Analysis Note

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.
