Leica SM2500 and SP2600 heavy duty sectioning microtome and micromilling device used to section large area samples up to 250 mm L x 200 mm W x 70 mm H. It is equipped to handle large and/or hard materials or samples such as mineralized bone and teeth. It will section samples in a range of 1-1,000 microns in 1 micron increments. The SP 2600 attaches to the SM 2500 expanding its capability by adding micromilling capacity, for surface preparation of samples. The SP 2600 is a milling device which will mill samples in a range of 500-3,000 rpm in 500 rpm intervals. The SP2600 produces a highly polished surface of varying sample types which are suitable for reflected light microscopy techniques, or any other surface analysis technique requiring a flat surface. It is particularly well suited for samples that contain hard and soft areas adjacent to each other. The SP 2600 removes carefully controlled layers from the surface of the sample by using a variety of milling tools from tungsten carbide to diamond. A special vacuum enhances operator safety and reduces clean-up by removing most of the milling debris as it is produced
