GEO Line for Petrography, Mineralogy and Geology

GEO Line is the complete range of instruments for petrographic sample preparation, starting with a piece of rock and finishing at 20 microns.

The existing product range offers the latest technology and functional design to provide high performance in preparation of mineralogical samples and thin section specimens.

For mineralogical specimens, the surface is prepared for examination with a reflected light microscope and the preparation preocedure is basically similar to the preparation of metallographic specimens. Preparing thin sections, on the other hand , requires highly specialized equipment and skills because  the specimen is extremely thin, generally around 20 microns for observations with transmitted light microscope.

Petrography Equipment - GEOCUT

GEOCUT -  Petrographic Cutter

  • Advanced Cutter for Minerals, Rocks and Geological Specimens
  • Cutter capacity for specimens up to dia. 100mm
  • Uses diamond blade 250/ 300mm
  • Linear Table Feed Cutting method
  • X-Y table bed with cutting cross feed
  • Various Clamping systems available

GEOCUT consists of cast aluminium based on which the motor and the working space are provided in the form of two separate housing. A large window of Lexan and a sealed 12V lamp in the cutting chamber allow precise observation of the cutting process at an optimum degree of safety. A large feed table located in the cutter’s work area can accommodate a variety of different clamping devices which need to be selected. The feed table provides a long travel depth, making the GEOCUT ideal for cutting long or deep samples in a single pass. Cross-feed table with digital read-out is available for parallel cutting and serial cutting. Cooling water recirculating system is an optional part of GEOCUT. Cooling is effected by two water jets located on both sides of cutt-off wheel.

GEOCUT cutting machines have the highest safety standards. The interlocking safety device does not allow the motor to be started unless the hood is closed. The hood cannot be opened before the cutting motor is stopped. The electronic brake system, which is a standard feature, brings the cutter to a quick full stop in seconds after it has been switched off.

Clamping Devices for GEOCUT  Petrographic Cutter:

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, QUALITEST offers a number of special clamping devices for use with GEOCUT petrographic cutter.

GEOFORM – Thin Sectioning System

  • Precision thin sectioning instrument for mineralogy
  • Cutting and Grinding processes combined
  • Specimen Holder with Vacuum for standard slides
  • Build in micrometer with digital readout.
  • Water cooling

Highly precise instruments are required for preparing thin sections and know-how. GEOFORM has two parts: Cutting and Grinding. On the cutting module, the specimen is fixed on a holder with vacuum and re-selected upto a thickness of approximate 0.5mm. Water cooling during cutting avoids deformation. GEOFORM can accommodate diamond and CBN cut-off discs upto 200 mm diameters.

GEOFORM is a bench-top 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.

The grinding module is designed for precision grinding. A universal vacuum holder accepts different sizes of glass slides by changing the location pins. A vacuum pump delivered as standard holds the glass slide fixed on the holder during grinding process. A built-in digital micrometer ensures high precision and the specimen is ground with an accuracy of 2 microns. Diamond cutting disc and grinding wheels are both on the same spindle which is precisely alligned for highaccuracy.A dualin-line fiHaringunit removes the moisture from the vacuum line and drains into the cutting chamber When the vacuum pump is turned off.

Petrography Equipment - FORCIPOL 300-1V

Petrography Equipment - FORCIPOL 300-1V

FORCIPOL 300-1V is a strong grinding and polishing instrument with variable speed between 60-600 rpm and for 300 mm diameter wheels. By using appropriate working discs, it can carry the grinding, lapping and polishing processes very smoothly.

Petrography Equipment - FORCIMAT-TS

Petrography Equipment - FORCIMAT-TS

Automatic Lapping and Polishing System for Thin Sections

  • Automatic Operation
  • Single force application for petrography
  • Special holders for thin section lapping and polishing.

FORCIPOL, when coupled with FORCIMAT –TS becomes an automatic thin section preparation system. FORCIMAT-TS is an automatic head with low speed for thin section and petrographic sample preparation. The force is individually applied and adjustable from the front panel.

Thin section holders LAP-Holder and POL-Holder ensure plane and perfect surfaces. LAP-Holder has Boron Carbide stops for precise lapping whereas POL-Holder is used for polishing process.
