Abstract: The present invention relates to a method of, and an apparatus for rinsing materialographic samples. The apparatus includes a sample holder configured to receive materialographic samples, a rotation head configured to rotate the sample holder and a vessel configured to receive the sample holder and a rinsing liquid. The apparatus also includes means for filling and emptying the vessel with rinsing liquid, means for applying ultrasound to the rinsing liquid and a control means. The control means is configured to control at least one of filling of the vessel with a rinsing liquid by injecting rinsing liquid through an inlet provided in the vessel to submerge the materialographic samples in the rinsing liquid, subjecting the rinsing liquid and the materialographic samples to ultrasound, or rotating the sample holder including the materialographic samples relative to the vessel.

Abstract: A method of embedding a sample material in a mounting medium with reduced cycle times and a mounting medium for embedding a sample material. The method includes the steps of: preparing a granular mounting medium by blending a granular resin and a granular filler, placing a sample material and said granular mounting medium in a moulding cavity, followed by the steps of: heating, for a first period of time, said moulding cavity including said granular mounting medium thereby producing a sintering mounting medium, cooling, for a second period of time, said moulding cavity including said mounting medium thereby producing a solid mounting medium embedding said sample material.

Abstract: The present invention relates to a method of, and an apparatus for, rinsing materialographic samples. The method includes the steps of: arranging one or more materialographic samples in a sample holder; connecting the sample holder (10) to a rotation head of a rinsing device; placing the sample holder connected to the rotation head in the vessel of the rinsing device; rotating the sample holder relative to the vessel; filling the vessel with a rinsing liquid; and subjecting the materialographic samples in the sample holder to ultrasonic waves.

Abstract: A specimen mover (100) for a grinding and/or polishing machine (120) is disclosed. The specimen mover (100) is configured for rotating one or more specimens (50) in abutment with a preparation surface (75) carried by the grinding and/or polishing machine (120) and the specimen mover (100) includes: a drive housing (20), a driveshaft (30) protruding from said drive housing (20), a thrust housing (10) disposed coaxially on said driveshaft (30) and including at least one thrust pad (12), and a specimen mover plate (15) disposed essentially coaxial with said thrust housing (10) and/or said driveshaft (30) The specimen mover is configured such that the thrust housing (10) is displaceable connected to the driveshaft (30) protruding from said drive housing (20) in a manner allowing the thrust housing (10) to move along, and relative to, the driveshaft (30) protruding from said drive housing (20).
