EXAKT three ointment mills deliver results that are consistent and reproducible.

A comparative study conducted at the University of Hamburg, Institute of Pharmacy in Hamburg, Germany concluded that the quality of ointments processed with EXAKT ointment mills is better than those processed with electric mixing systems. The study highlighted the following conclusions:

  1. The particle size is smaller and the particle size distribution is narrower.
  2. Ointment stability is better.
  3. Temperatures do not increase significantly during processing.
  4. Ointments are softer consistency with lower flow limits.
  5. Ointment mills allow for quality control during processing.

3 Distinct Advantages Using EXKAT Ointment Mills

EXAKT ECPlus & Classic50-Pharmacy-Counter

Ointment mills (three roll mills) offer a distinct advantage over other mixing techniques. Only the ointment mill used in the dispersing process guarantees that 100% of the product will be passed through both shear zones. This is why no mixer can do what an ointment mill does.

  1. The shear rate between the rollers is the decisive factor for the process.
  2. Agglomerates and powder clumps are broken up and homogenized.
  3. The more controlled the energy input, the more precise the processing.

For producing truly elegant preparations of creams, ointments, or gels there is no tool more effective or more complete than an EXAKT ointment mill.

EXAKT Dispersion Process

What does an ointment mill do?

EXAKT-80E-Plus-with-Hopper

An ointment mill utilizes high shear force to disperse active ingredients, and homogenize viscous materials. Shear force is created by three horizontally positioned rollers rotating in opposite directions and at different speeds relative to each other.

The product is pulled through the gaps between the rollers. Active ingredients and powder clumps are broken up and homogenized, which removes grittiness and results in a high-quality topical.  This gives your customers a pharmaceutically elegant and effective ointment.
