Sample collection and dispensing device

A sample collecting and dispensing apparatus comprising:

• a capillary sampler disposed on a device first end, wherein the capillary sampler is configured to collect and dispense a fluid sample via an opening and a capillary body;
• a reagents chamber storing a fluid reagent specific to the fluid sample to be collected, wherein the reagents chamber includes a reagents chamber distal end attached to and in fluid communication with the capillary sampler and a reagents chamber proximal end;
• a liquid barrier disposed on the reagents chamber distal end configured to prevent the fluid reagent from passing from the reagents chamber to the capillary sampler under atmospheric pressures;
• and
• a plunger assembly including a handle and a plunger rod disposed on a device second end, wherein the plunger assembly is adjacently connected to the reagents chamber proximal end through mated threads, and wherein the plunger rod is configured to translate distally along the reagents chamber to decrease a volume of the fluid reagent in the reagents chamber and permit the fluid reagent to release from the reagents chamber.
