Case #4: Purification of high-viscosity solution

Problem

  1. Still standing cannot defoam in emulsifying agent and sealant etc. in spite of spending a long period.
  2. Filtration cannot remove sludge in cosmetics.

Solution

  1. Centrifugation can defoam in high-viscosity sample in a short time. Defoaming agent is not required. Dissolved gas can be removed too.
  2. Centrifugation can remove sludge (particle) in high-viscosity sample, such as cosmetics, which could not be removed by filtration.
Centrifugal defoaming

Discussion
Centrifugation can remove particles in high-viscosity sample, which cannot be removed by filtration. Centrifugation can defoam in high-viscosity sample in a short time.

Recommended centrifuges are micro ultracentrifuge model CS150NX or CS150FNX.
