Replica foil

Replica foil is used to make a replica of any polished and etched surface. The foil is particularly useful when micrographs of an on-site prepared structure are required or analysis using a portable microscope is insufficient.
Replica foil consists of reflecting plastic film with a self-adhesive backing.
A replica is made by applying fluid to the film and pressing it firmly onto the prepared and etched surface. After 4-5 minutes, the foil is removed from the surface. By removing the cover paper, the replica can be adhered to a plain plate and then examined under an optical microscope.
