Hydrophilic microplates for vertical beam photometry
First Claim
Patent Images
1. A method for improving the precision of optical density measurements made utilizing a vertical beam photometer to determine the presence or amount of analyte in the wells of a microplate, which comprises:
- treating the surfaces of the wells of said microplate in order to increase the hydrophilic character of said surfaces prior to adding aqueous sample or reagent to said wells.

Abstract
A microtiter plate prepared from a hydrophobic plastic is rendered more hydrophilic by treatment of the surfaces of the wells of the microplate prior to use. The resulting plates are particularly useful in vertical beam photometry.
