Micropol™ Polisher For TEM & Metallography – Model MC3
polisher is a compact, versatile, electrically controlled, precise mechanical specimen grinder/polisher designed for planar grinding, dimpling, thinning and polishing of specimens in the fields of nanotechnology, semiconductors and material science. The parameters of polishing (speed, load, time, etc.) can be matched according to the properties of the specimen. High quality samples are prepared with minimal efforts by the operator.
Micropol™
FEATURES Rugged, corrosion proof construction
MicroPol Parts Variable speed control for precision polishing
Quick change bayonet mount bowls Timer for automatic operation Extremely light load for fragile TEM samples
While the Micropol™ MC3 is well suited for metallographic polishing, it has been specially designed for precision TEM polishing applications. Two types of specimen holders are provided with each unit that makes it ideal for the preparation of both planar and dimpled samples, respectively.
Application Operation
The arm of Micropol™ moves the specimen holder or the specimen itself in a semi-random geometric pattern gently pressing it to the bottom of a bowl containing suitable abrasive material. The abrasive material can be grinding paper or suspensions of polishing compound deposited on polishing cloth.

Figure 1.
The most difficult step of cross-sectional thinning is the mechanical preparation of the sample, i.e. cutting a cross section and then embedding it into an appropriately designed ring.
We now offer a convenient, specially designed embedding ring for cross-sectional samples, shown schematically in Figure 1.
Using this ring, embedding cross sections is greatly simplified, since the samples do not need to be glued together prior to embedding. In order to fix the sample(s) in the ring it is deformed mechanically by an appropriate tool at the two points marked by the arrows. This deformation will both hold the sample in the ring and press both sample pieces together before gluing.
Ti disc is also offered for embedding bulk samples of brittle material for plan-view TEM investigations. The rings come in 5 sizes-0.6, 0.8 1.0, 1.2, 1.3 mm.
