Hitachi Koki Co.,Ltd.

Centrifugation is well established technique and widely used in biology and life-science field.
Main purpose of the centrifugation is;

  1. Classification (separation),
  2. Purification,
  3. Condensation.

Especially, high-speed centrifuges and ultracentrifuges are powerful tool to separate sub-micron-sized particles and nanosized particles, because of their greater g force, max. 1,050,000xg.

As a development of the material science, the particle size of the newly developed material is getting smaller and smaller. Recently, there are some difficulties or problems encountered to separate and/or purify the sub-micron-sized or nanosized particles in development, production or quality evaluation with conventional methods and alternative methods are required to solve the problems and the difficulties. Therefore, high-speed centrifuges and ultracentrifuges have been getting a lot of attention as the alternative method of filters or general purpose centrifuges etc.

High-speed centrifuges and ultracentrifuges can be applied for;

  • Nanosized partcles
  • e.g. classification or elimination of pigment components
  • Ink sample
  • e.g. classification of suspended particles in size
  • Suspension sample
  • e.g. classification and purification of carbon nanotubes
  • Emulsion sample
  • e.g. classification of cosmetic ingredients
  • Latex particles
  • e.g. classification in size and density
  • Metal nano-colloid
  • e.g. purification of metallic particle in the colloid.
  • and more.

As a result of the classification, purification and concentration of the sample with high-speed centrifuges and ultracentrifuges, sensitivity of sample measurement can be improved and be more effective.

We are pleased to propose high-speed centrifuges and ultracentrifuges for;

  • Development stable suspensions and/or emulsions,.
  • Analysis of storage stability,.
  • Efficient development of adjustment method of fluid dispersion.
  • Selection of dispersant and determination of its optimum additive amount.
  • Quality monitoring in production process.
  • Acceleration of the aging test.
  • and more..
