The Kemet 300LVAC2 Special purpose polishing machine is designed to work alongside the Kemtech III Geological lapping machine for polishing geological mounted samples.

FORCIMAT-TS is driven by a 100 Watt DC motor and adjustable from 25 to 50 RPM speed which provides high torque for big specimens and allows long operation time. PetroThin is the only machine in the world that can perform the required type of grinding on an inexpensive, rapid, and routine basis. Rush Orders: One week, limit six rock samples. A signed order form (provided below) must be delivered to the lab before work can begin on your samples. Prices and requisition form are available at the bottom of the page. When the start button is pressed, both the FORCIMAT-TS and FORCIPOL-TS start operating simultaneously. FORCIPOL-TS is a versatile, durable and reliable grinding/polishing machine.

The training needed to operate the equipment and prepare thin sections in a consistent manner can be accomplished within one week.

We buy our equipment from a range of suppliers such as Kemet, MetPrep, Buehler, Struers, Brunel Microscopes,Husqvarna and Logitech. Our Thin Section Laboratory is currently closed but will remain open for rock saw usage if you are already trained.

Athletics Graduate Student Government Thus, it is possible to prepare 20 m thick slices quickly and accurately. Please stop by the office (147A) and say hello prior to beginning your work. All equipment and work stations must be thoroughly cleaned before you leave. By using appropriate working discs, it can carry grinding, lapping and polishing processes very smoothly. A huge thank you to all who collaborated on these projects. The pneumatically applied individual force is adjustable between 5 N (1.1 lb.)

Map and Directions.

The bulk of our work is producing sample sets for our extensive research base here at Ocean and Earth Science. The samples we produce are used extensively in the 1st, 2nd and 3rd year geology courses as teaching sets for microscopy.

Alternatively, the specimen is polished if it will be used for scanning electron microscopy (SEM) or microprobe analysis. PetroThin is the ultimate thin section preparation machine. Additionally, it is desirable to have access to a fume hood, drying oven, equipment for vacuum impregnation of the samples, and a rugged diamond saw for rough cutting of larger samples.

Specially designed thin sections holders are used for lapping and polishing of thin sections.

The machine is easy and safe to operate. When needed, FORCIMAT-TS can work in manual mode to allow prepare specimens by hand.

All parameters can be changed during operation. In addition to reflected and transmitted microscopy our samples go on to other laboratories within the faculty including: SEM, Laser Ablation, GAU-Radioanalytical Laboratories, and XRD.

The PetroThin requires access to 380 VAC, cold water, and a vacuum source.

Calendar After Sales Service and Technical Support. Additionally, we will provide courses in concrete petrography, optical microscopy, and SEM/Microprobe analysis. Equipped with Logitech semi-automated lapping and polishing machines, the Thin Section Lab is able to hold roughly a one-micron flatness tolerance during the critical phases of thin section preparation. This facility prepares rock and other hard materials in-house for the School of Ocean and Earth Science, other university departments as well as outside organisations.

Sample force, wheel speed, sample holder speed, operation time, motor on/off and water on/off functions can be set in seconds.

from the front panel and is displayed on a gauge.

In the Fall, we will open a permanent full-time Laboratory Coordinator position and convene a search committee with interested GGE faculty at that time.

Automatic Disc Cleaning and drying function can be activated with a single button to obtain perfectly cleaned disc surfaces in seconds. The last parameter settings are always retained in the memory. The wheels are mounted on ball bearings allowing the application of high pressures to prepare even large specimens. When the epoxy has cured, excessive epoxy is ground off plus 7 m into the material.

Below please find some valuable teaching resources for online thin section and rock sample identification. Cooling water is automatically activated and deactivated at the beginning and end of operation.

The working wheel is powered by a high torque 1.0 HP electric motor with both clockwise and counterclockwise wheel rotation possibility. The preparation of thin sections represents a fundamental step required for the study of minerals and rocks in geoscience. Please report any misuse, broken/malfunctioning equipment, unsafe work practices, or laboratory improvement suggestions to the laboratory coordinator. The final thickness of specimens will be between 25 and 35 m. For the remainder of this summer 2021, recent MS graduate, Kelsey Livingston ([emailprotected]), will continue to help manage our Thin Section Lab on a part-time basis, keeping access available to the rock saws and other peripherals, with oversight. Upon completion of the cycle, both instruments stop and an audio signal notifies the operator. FORCIMAT-TS is a low speed automatic head and is mounted on a rigid hardened post which is fixed to the base of the FORCIPOL-TS grinder/polisher.

The thickness is controlled by checking the birefringence colors of quartz or feldspar particles using a polarizing microscope or by direct measurement with a caliper.
