Consumable components in fluidic sample dispensing systems and methods

A sample dispenser for dispensing substantially a same volume of liquid-based sample material to a plurality of targets, the sample dispenser comprising:

• an inlet port to receive the liquid-based sample material;
• a first tubular structure having a first inner volume and a first inner perimeter, wherein:
• (i) a first opening of the first tubular structure is disposed between a first gas nozzle and a first target, wherein the first gas nozzle is configured to expel gas towards the first target, and
• (ii) the first inner perimeter is selected such that capillary action can be induced to fill the first tubular structure with the liquid-based sample material via a second opening of the first tubular structure;
• a second tubular structure having a second inner volume and a second inner perimeter, wherein:
• (i) a first opening of the second tubular structure is disposed between a second gas nozzle and a second target, wherein the second gas nozzle is configured to expel gas towards the second target, and
• (ii) the second inner perimeter is selected such that capillary action can be induced to fill the second tubular structure with the liquid-based sample material via a second opening of the second tubular structure;
• and
• a tubular junction that fluidically couples the inlet port to the first tubular structure and the second tubular structure,
• wherein an average cross-sectional area of the tubular junction is less than an average cross-sectional area of the first tubular structure and the second tubular structure,
• wherein the first inner volume and the second inner volume are substantially same, and wherein the second opening of the first tubular structure is proximate to the second opening of the second tubular structure.
