상세설명


micromod Zetapotential Kit
Sulfonated micromer®
micromod Zetapotential Kit – Sulfonated micromer® checks the whole range of negative Zetapotentials
  • with sulfonated latex particles of a constant diameter (2 µm)
  • with well defined Zetapotentials up to –70 mV
  • with clearly defined conditions for the Zetapotential measurement
Test the beads for your application, e.g.:
  • protein binding assays
  • model studies in ecology
  • surface modifications of membranes or films
The micromod Zetapotential Kit – Sulfonated micromer® contains
  • latex particles with a plain surface as reference, micromer® (white), and
  • 3 types of sulfonated latex particles, micromer® (yellow), micromer® (red) and micromer® (blue)
Zetapotential values of the latex particles
The Zetapotential values of the latex particles strongly depend on the concentration of the background electrolyte, but slightly on the particle concentration.

For optimal Zetapotential measurements we recommend:
  • the use of 0.001 M – 0.0001 M KCl solution as electrolyte medium for a standard measurement
  • a particle concentration of about 5 – 10 µg particles per ml electrolyte (e.g. dilution of 10 – 20 µl 1% particle suspension (10 mg/ml) in 20 ml electrolyte medium)
  • the use of 0.0001 M KCl solution as electrolyte medium for the determination of the Zetapotential–pH-function and the pH titration with the system 0.1 M HCl / 0.1 M KOH to prevent additional foreign ions
