Electron Microscopy Sciences UniDisc MK2 3 mm Disc Punch
Supplier: Electron Microscopy Sciences 5523008
The standard UniDisc is to produce 3mm disc from samples 0.004 to 0.006" (0.10 to 0.15mm) thick for electropolishing, and subsequent TEM examination, from sample strips. Larger disc specimens can be used for SEM.
Sample strips are fed into the side of the UniDisc. When the handle is pulled, the strip is trapped between two rigid metal die faces. The punch then pierces the tightly held sheet and ejects the disc into the collection tray. Deformation is confined to a much localized shear zone at the edges of the discand is later thinned using either a jet electropolisher. Suggested Accessory for Twin Jet Electropolisher Model 501B.
