The PetroThin Thin Section Machine is a versatile, 8in [203mm] tabletop cutter and grinder, perfectly suited for crafting thin sections of a wide range of materials, including bone, ceramics, concrete, petrographic samples, and more.

 — A grinder pump is a sewage ejector pump that processes wastewater from the home's plumbing system by shredding solid material. A grinder pump is placed in a basin or tank, typically buried in a convenient location on the homeowner's property.

With the semi-automatic grinding and polishing machines both single and central pressure can be applied. The central pressure allows grinding and polishing of mounted, unmounted and oversized specimens. In combination with a removal measurement, grinding can be done automatically to a defined sample height if required.

In its various forms grinding can be used on wet, dry, and frozen samples, however it is most efficient on solid samples. One key characteristic of grinding is that friction generates heat and at times can be significant. Consequently, the heat tolerance of the analyte should be considered when selecting a grinding method.

KBr pellets/disks (for solid samples) In order to prepare a KBr pellet, follow the procedure given below: Chemistry Analytical Lab FT-IR Spectroscopy Sample preparation for FT-IR. ... excessive grinding of the potassium bromide is not required. The finely powdered potassium bromide will absorb more humidity (it is hygroscopic) from the air and ...
