Portrait The Advalytix technology uses surface acoustic waves (SAW) for precise manipulation of minute fluid volumes. SAW-pumps contain no moving parts and are contamination-free. The SlideBooster(tm) incubation system for DNA- and protein-microarrays utilizes SAW-fluidics to agitate the sample solution during hybridization. The micro-agitation enhances signal intensity, homogeneity and reproducibility.
