Description
Replication Materials
Cellulose acetate tapes and sheets provide a quick and convenient way for replicating surfaces particularly from samples which can not be sectioned or investigated directly.
The replication materials are available in a variety of sizes and thickness to cover a wide range of applications.
They soften in acetone and can be applied to a surface which has been wet with acetone.
They are stripped off when dry.
Thicknesses of 22 is used for finer detail replication.
Tri-acetate, a thicker (130 m) replicating sheet, is suitable for replicating rough surfaces.
For fine detail, positive replicas can be made by coating the surface of the replica with carbon in a high vacuum carbon coater and then dissolving the replication sheet.
The carbon replica can then be examined in the TEM.
Alternatively, the replica can be coated with a conductive coating (such as gold) and examined in the SEM as a negative replica.
The replication sheets are supplied in packs of 20.
