Many configurations of the Stat Fax 4500 feature a vacuum-driven fluidic system designed to draw samples into a micro-flowcell. A peristaltic pump or vacuum pump regulates the aspiration volume. Precise fluidic calibration ensures that the sample completely fills the optical path without introducing micro-bubbles, which cause severe absorbance drift.
