Abstract:
A method of making a microplate for assaying samples having at least first and second wells, each of the first and second wells having sidewalls and a bottom, the method comprising steps of:(A) inserting a sheet of a first plastic material into a mold cavity that includes sections shaped to form the sidewalls of the first and second wells so that the sheet is positioned to form the bottoms of the first and second wells, the first plastic material having an average optical density no more that approximately 0.09 at a thickness of approximately 7.5 mils between wavelengths of approximately 200 nm and approximately 300 nm, bottoms of the first and second wells having a thickness of less than approximately 14 mils;(B) injecting a molten plastic material into the mold cavity; and(C) cooling the plastic material to form the microplate with the plastic material forming the sidewalls of the first and second wells and the sheet of the first plastic material forming the bottom of each of the first and second wells.
