Abstract
Method for manufacturing a preparation carrier, in particular suitable for use in chemical and biochemical research, wherein: on at least one surface of a carrier base, a layer of plastic is provided, wherein the plastic layer is treated thermally and/or chemically, such that the surface roughness of the side of the plastic that faces the carrier base is reduced, while it does not adhere to the carrier base, whereupon the plastic is removed from the carrier base, with the released, relatively smooth surface of the plastic forming a carrier surface.
Claims19
A method for manufacturing a preparation carrier, wherein:
- on at least one surface of a carrier base, a layer of polyethene or polypropene is provided, wherein the carrier base is a surface formed from mica or glass or a material having a flatness V of about 0.1%-0.3%,
- wherein the plastic layer is treated thermally and/or chemically, such that the surface roughness of the side of the plastic that faces the carrier base is reduced such that the flatness V is less than 3%, while the plastic does not adhere to the carrier base,
- whereupon the plastic is removed from the carrier base, with the released surface of the plastic forming a carrier surface,
- wherein the flatness V is expressed in the formula Z-axis/X-axis×100% with the X-axis being between 2000-4500 nanometer.
