Abstract

The micro titer plates, especially for micro reaction systems used in biotechnology, each have an array of special microstructures, which typically include micro cups and micro channels with different cross-sections. These microstructures are introduced into a preferably borosilicate glass wafer (18) by ultrasonic machining. Individual rectangular micro titer plates (19′) made from borosilicate glass for biotechnology are produced by cutting the structured glass wafer into individual micro titer plates. Particularly arrays of from 10 to 100 of these microstructures are formed in a 6-inch borosilicate glass wafer, in order to facilitate subsequent cutting of the wafer to economically manufacture a corresponding number of these micro titer plates (19′).
