An ideal accessory to the Model 110 Automatic Twin-Jet Electropolisher. The specimen punch is available with a standard base or with a wide base, which provides extra stability when producing thin foils.

A precision ground punch and die plate eliminate specimen stress and distortion of the disk specimen. A spring-loaded return plunger keeps the disk specimen on the die plate surface for convenient handling.

Available in standard sizes of 1 mm, 2.3 mm, and 3.0 mm; other sizes available upon request
