Abstract
A method of filling a microchannel formed in a component of a fluidic microsystem, the component being made of a plastics material or an elastomer suitable for absorbing gas, the method consisting in degassing the component and then in inserting a liquid into a feeder well of the microchannel, which liquid fills the microchannel because of the suction produced by the material absorbing the gas contained in the microchannel.

A method of filling a microchannel in a component of a fluidic microsystem, the component being made at least in part out of a plastics material or out of an elastomer suitable for absorbing the gases with which it is in contact, the method comprising subjecting the component to degassing under a vacuum, then placing the component in a surrounding or ambient atmosphere, inserting a liquid in the microchannel of the component, and filling the microchannel with the liquid by allowing the suction that results from the component absorbing the gas contained in the microchannel to act on the liquid.
A component of a fluidic microsystem, made at least in part out of a plastics material or an elastomer capable of absorbing gas and including at least one microchannel that is to be filled with a liquid, the component being previously degassed under a vacuum and is packaged under a vacuum in a hermetic package.
