Abstract

A method of preventing false detection of signal due to splashing of reagent liquid used to produce such signal, when dispensing at least one such liquid from a metering tip into a second liquid, comprising the steps of: a) positioning the metering tip a predetermined distance above the upper level of the second liquid prior to dispensing the one liquid; and PA1 b) while maintaining the distance throughout the dispensing of the one liquid, dispensing the one liquid; PA1 wherein the predetermined distance is between about 1.0 mm and about 2.0 mm so that splashing during dispensing is reduced.
