Abstract
A device for sampling, transporting and/or disposal of fluid media in the nl and μl-range comprises a substrate with an open or closed capillary-like groove or channel respectively, the substrate with the open or closed groove or capillary respectively is bent or arcuated at least at one location. The substrate comprises at least one end into which the open or closed capillary-like groove or channel respectively is extended, which end is shaped according to its application or use as e.g. needle-like, straight-lined cut, tip-like, at least most half circle-shape, rounded, etc.
Claims18
A device for sampling, transporting and/or disposal of fluid media via capillarity in the nanoliter (nl) to microliter (μl) range comprising a circular substrate defining a substrate plane and having at least one longitudinal extending strip like portion which is bent at least at one location out of the substrate plane, said strip like portion extends radially and is provided with a fluid channel which provides a capillary force to the fluid media when contacted therewith, wherein the longitudinal extending strip like portion is a spring-like element with an arcuate curve in the direction opposite the bend.
A method for producing a device used to sample, transport and/or dispose fluid media via capillarity in the nanoliter (nl) to microliter (μl) range comprising:
- providing a circular substrate which defines a substrate plane;
- providing at least one longitudinal extending strip like portion within the substrate, said strip like portion extending radially, having at least one fluid channel and having an end;
- and
- bending the longitudinal extending strip like portion at a location such that said end is out of the substrate plane.
- wherein the longitudinal extending strip like portion is a spring-like element with an arcuate curve in the direction opposite the bend.
A device for sampling, transporting and/or disposal of fluid media via capillarity in the nonoliter (nl) to microliter (μl) range comprising a circular substrate defining a substrate plane and having at least one longitudinal extending strip like portion which is bent at a right angle at least at one location out of the substrate plane, said strip like portion extends radially and is provided with a fluid channel which provides a capillary force to the fluid media when contacted therewith, wherein the longitudinal extending strip like portion is a spring-like element with an arcuate curve in the direction opposite the bend.
