Technology behind Specimen

Petrography is the science of investigating microstructure, composition and inter-component relationship of rocks, ceramics, minerals, man-made materials etc. The method of prepare petrographic samples for investigation is called "thin-sectioning". Preparation of thin-sections require very precise instruments and know-how. METKON offers complete range of instruments for petrographic preperation, starting with a piece of rock and finishing at 20 microns

GEOCUT 302 GEOCUT 302 is an Advanced Geological Cutting Machine that is ideal for sectioning of rocks, ceramics, minerals, glass, concrete and geological specimens. • Modern and sturdy design • Extraordinary access for easy handling • Ability to use Ø250/300 mm diamond blade. • Cutting capacity up to 110 mm in diameter. • X-Y Cross table is available as standard for parallel and serial cutting. • Linear Table Feed and Chop Cutting methods • Various Clamping systems available for small to large size or irregular sample shapes. GEOCUT 302 GEOCUT 302 is specially designed for cutting large and...

CLAMPING DEVICES Quick Clamping Device for round petrographic specimens Universal vise for large specimens, rocks, etc. Vertical Clamping Device with clamping shoe Many petrographic cutting applications require the sectioning of a specimen from an irregular shaped sample. The small size or irregular sample shape can create positioning and clamping difficulties for the operator. To overcome these difficulties, METKON offers a number of special clamping devices for use with GEOCUT 302 petrographic cutter. ACCESSORIES FUMEFILTER An advanced fume and mist removing unit that is optionally available...

GEOFORM 102 GEOFORM 102 is a bench-top thin sectioning instrument that will cut and grind down to 30 microns or less depending on the hardness of the material because; mineralogical specimens usually contain hard and soft phases. GEOFORM 102 has two parts: Cutting and Grinding compartments. • Two machines are combined in the same body: Cutting and Thin Sectioning. • Large cutting compartment with movable T-table • Ability to mount clamping devices • Colored LCD touch screen with advanced software • Variable wheel speed, 500-2000 RPM • Completely closed cutting and grinding compartment with...

Touch Screen Controls Variable Wheel Speed GEOFORM 102 is equipped with 7" HMI touch screen with advanced software that allows extremely simple and professional operation with repetable results. It increases the productivity, sample consistency and minimize operator intervention. Integrated speed regulating unit allows variable wheel speed, soft start/stop function and smooth operation for maximum precision. Possible to adjust the wheel speed between 500-2000 rpm, which makes it suitable for the wide range of materials. CLAMPING DEVICES AND VACUUM CHUCKS Quick Clamping Device Vertical...

VACUMET 52 • Compact and simple • Built-in vacuum sytem with Gauge • Efficient impregnation • Multi-specimen application. VACUMET 52 is designed for embedding and impregnation of porous materials. It removes the trapped air from the mounting material and eliminates the gaps between the specimen and the resin. Most mineralogical specimens have porosities, cavities and cracks and therefore need to be under vacuum. VACUMET 52 fulfills this requirement easily and efficiently. In addition, VACUMET 52 can also be used for glueing the specimens on the glass slides for further processing in thin section...

IPP 902 is a Polarization Microscope and it specially designed for petrography. It has robust dye-cast frame to provide high stability and ergonomy. It has three different observation modes: Brightfield, Transmitted polarized light, Incident polarized light. High quality optical system provides extremely clear images for petrographic examinations. Illumination The light source for transmitted illumination is 3.6 Watt white LED system, which is comparable to an halogen bulb 50 Watt. The light source for incident illumination is 8 Watt white LED system, which is comparable to an halogen bulb...

Sectioning The rock is cut from area of interest for analysis. GEOCUT 302 Sticking Specimen The specimen is bonded to glass slide with adhesive resin. Resectioning Re-sectioning of the specimen to a thickness of 0,5 - 2 mm to shorten the grinding process Precision Grinding The specimen is pre-polished to a thickness of 80µ (specimen + resin) Lapping & Polishing Automatic lapping & polishing of thin section with LAP-TS and POL-TS. Final thickness 25 – 30µ (specimen + resin) FORCIPOL TS with FORCIMAT-TS Microscopy The thin section is ready to be observed under polarized light microscope IPP...
