Aka-Brief Aka-Brief is a preparation method with all the parameters for the individual preparation steps. In addition, a micrograph is shown with the expected preparation result after each step.This makes it possible for you to determine whether the individual steps have been successfully completed or if something needs to change. There are two different types of preparation methods: Specific Methods for certain materials and General Methods for a range of materials based on their hardness. All methods are carefully optimized to provide the best possible quality at the lowest possible cost.
