Micro particles based on melamine resin

Description

• General description: Melamine resin-based microparticles (size: 10 μm) are a size standard, ideal to determine 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 them (powders are available on request).
• Application: Used to calibrate and monitor particle counting and sizing equipment.
• Features and Benefits: suitable for routine instrument calibration checks and correctionsextremely high stability in organic solventsno swelling or shrinking upon contact with organic solventsaqueous suspensions are stable to repeated freeze-thaw cyclesavailable in 10 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 0.01 μm using a Coulter Multisizer. Density: 1.51 g/cm3Heat resistance <300 °CChemical 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.
