설명

일반 설명

Melamine resin-based microparticles (size: 8 μm) are a size standard, ideal for determining the particle size distribution (PSD) profile of test samples.
The product contains hydrophilic surfaces with high degree of cross linking and high pressure resistance. Lyophilization and resuspension in aqueous media does not damage the product (powders are available on request).

애플리케이션

Used for equipment particle size calibration.
Also used to identify melamine resin microparticles in seawater samples.

특징 및 장점

• suitable for routine instrument calibration checks and corrections
• stable to repeated freeze-thaw cycles
• available in 5 mL pack size as a neat sample

분석 메모

For every lot, exact values of particle size and standard deviation are determined with an accuracy of 0.01 μm using a Coulter Multisizer.
Density: 1.51 g/cm³
Heat resistance <300 °C
Chemical resistance: acids, bases, organic solvents
Monodisperse melamin resin particles are characterized by high uniformity and narrow size distribution. They carry functional methylol groups, which can be used for covalent coupling of biological active compounds.
