Case #4: Purification of high-viscosity solution
Problem
- Still standing cannot defoam in emulsifying agent and sealant etc. in spite of spending a long period.
- Filtration cannot remove sludge in cosmetics.
Solution
- Centrifugation can defoam in high-viscosity sample in a short time. Defoaming agent is not required. Dissolved gas can be removed too.
- Centrifugation can remove sludge (particle) in high-viscosity sample, such as cosmetics, which could not be removed by filtration.

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.
