The 4" diameter polished platens are useful for making large diameter polymer films. The platens are made from 1/2" thick 316SS. Platen surfaces are available polished to a mirror finish or lapped flat to a finely honed matte finish. Matte finish platens are useful for limiting fringing of polymer films which take on the surface characteristics of the platens against which they are pressed. There are ports in the platens to enable insertion of a thermocouple probe. The platens are also tapped with a female thread to allow attachment of an optional handle. The platens (0012-9419 and 0012-9420) can be configured with spacers to make a film of a consistent path length. The standard spacer provided with 0012-9419 and 0012-9420 creates a film thickness of 0.1mm, but custom spacers for specific thicknesses can be provided. Platens configured for a spacer also have run-off grooves to accommodate the overflow of excess sample.The platens are compatible with our standard heated platens (0012-6664).
