Abstract
A microfluidic dispensing system may include diaphragm pumps that may be used for aspirating in corresponding ingredients via a nozzle or a tip from supply sources. Tips may be placed in contact with ingredient supply sources, and through repeated actuation of the diaphragm pumps, desired volumes of ingredients are aspirated into the tips. In some cases, an air plug is aspirated into the tips before an ingredient. Once the desired volume of each ingredient is reached within each tip, the ingredients are dispensed from the tips through repeated actuation of corresponding diaphragm pumps.
