Is there still liquid in the sample? Was it insufficiently infiltrated or have bubbles occurred? These and similar questions come up at the end of a thin section preparation. Valuable samples can be »rescued« and the information content secured with the EXAKT 530 block drying and infiltration unit. Thus, for example, through vacuum and controlled heat, residual water can be drawn from an insufficiently de-hydrated sample, resin added and cured under blue light.
