Abstract
Embodiments in accordance with the present disclosure are directed to sample collecting and dispensing methods and apparatuses. An example apparatus includes a capillary sampler disposed on a device first end, wherein the capillary sampler is configured to collect a fluid sample via an opening and a capillary body. The apparatus further includes a reagents chamber in fluid communication with the capillary sampler, and a barrier assembly disposed between the capillary sampler and the reagents chamber, wherein the barrier assembly is configured to separate fluid in the reagents chamber from the capillary sampler. A plunger assembly disposed on a device second end opposite the device first end, may modify the barrier assembly to dispense the fluid from the reagents chamber to the capillary sampler responsive to application of a force in the direction of the device first end.
