Key Parameters for Fluidic System Selection in IVD Instruments
IVD fluidic systems require accuracy, stability, cleanliness, material compatibility and maintainability. Individual component selection affects the whole system.
A fluidic system depends on multiple components
An IVD fluidic system usually includes pumps, valves, tubing, fittings, needles and sensors. These components must work together to support aspiration, dispensing, washing, reaction and waste handling.
Parameters and supply capability
Common concerns include dispensing accuracy, repeatability, material compatibility, bubble control, dead volume, residue, interface consistency and lifetime. For mass-production instruments, product consistency and stable supply are also important.
