## About this tender

A bid is requested for one (1) thin section lapping and polishing equipment and/or for one (1) thin section/sample saw. Thin section lapping and polishing equipment: The thin section lapping and polishing equipment must be capable of producing polished thin sections, thin sections with surface glass, polished sections, and glued sections made from crushed material. GTK usually uses hot plate and oven impregnating with Araldite and Petropoxy adhesives for the production of thin sections. GTK uses a mineral and polarization microscope and a micrometer to inspect the quality and thickness of the grains. GTK produces thin sections from soft rock (shale) to very hard rock types (granite), as well as glued sections from crushed stone. As a general rule, the rock types in Finland are hard. GTK has an external Pfeiffer HiScroll 46 vacuum pump for the use of thin section lapping and polishing equipment so the vacuum pump is not within the scope of this invitation to tender. The most produced sections at GTK are as follows: Polished thin section and section with surface glass, size 48 mm x 28 mm, other sizes are also possible Polished section, size varies, normally sample is round, and the size is 25 mm x 30 mm. Glued gravel section, size varies, normally sample is round, and the size is 25 mm x 30 mm. The thickness of the polished thin section must normally be 0.03 mm, uniform in thickness, and the minerals must have the correct optical color for identification. The surface of the polished thin section must be scratch-free. and/or Thin section/sample saw: Thin section/sample saw is used for sawing bulk rock samples for thin section production. The size of rock samples varies from few cm up to 20 cm in thickness. The saw must be capable of cutting samples with a diameter of at least 10 cm and thin sections sized up to 50 mm x 75 mm. GTK has an external Pfeiffer HiScroll 46 vacuum pump for the use of thin section/sample saw so the vacuum pump is not within the scope of this invitation to tender. Delivery terms & warranty for both devices: Delivery term: DDP Geological Survey of Finland, Thin section laboratory, Kuopio, Finland. Incoterms 2020. Delivery at the latest by October 30, 2026. At least a two-year warranty from the acceptance of the equipment.
