title: Improvement of the positional dispensing in the washing machine MW 2001.
abstract: This article is about how to improve the positional dispensing accuracy of low-volume (microliters) drops and to understand the factors affecting them. These same parameters can be investigated to reduce deleterious effects on dispensing performance. Many applications, such as those in immunoassay diagnostics, require accurate volumetric dispensing and are also less tolerant of other phenomena that cause the reagent to be located outside the target area of interest. In this article, we work with liquid inertia. This phenomenon is present in positional dispensing and affects its accuracy. The negative effect of liquid inertia is reduced by changing parameters such as pressure and the diameter of the involved conducts.
