Metering Assembly And Method Of Dispensing Fluid
US Patent:
2009001, Jan 22, 2009
Filed:
Jul 19, 2007
Appl. No.:
11/880112
Inventors:
Kabir James Mukaddam - Jamaica Plain MA, US
Jennifer Ezu Hu - Falcon Hts. MA, US

Assignee:
Formulatrix, Inc. - Waltham MA
International Classification:
G01F 7/00, G01F 23/00
US Classification:
73196, 702 50
Abstract:
A metering assembly includes a fluidic chip and metering chambers. Selectable outlet valves communicate with each metering chamber to provide a discrete dispensed volume. The valves may be commonly controlled and may be formed as multi-level valves. The valves may be grouped into common substrate valve clusters. Purge channels communicate with the metering chambers and controlled purge valves allow reverse flow wash fluid to wash the metering chamber. Pressure ports are employed to actuate the valves. A method of dispensing a fluid from the fluidic chip includes a) selectively filling (or filling) the metering chambers with a selected fluid; and b) outputting (or selectively outputting) the fluid to output locations. The total output volume of fluid dispensed from each metering chamber may be accumulated. The process may be repeated until the accumulated volume equals the desired volume and may be repeated for another fluid from a plurality of different fluids.

Microfluidic Dispensing Assembly
US Patent:
8550298, Oct 8, 2013

Assignee:
Formulatrix, Inc. - Waltham MA
International Classification:
B67D 7/70, B67D 1/00, F16K 3/00, F15C 1/04, F17D 1/00, F17D 1/16, B01L 3/00, B01L 3/02, G01F 11/00, G01N 21/75, F15C 1/00
US Classification:

Abstract:
A microfluidic dispensing system may include multiple supply lines for simultaneous filling of diaphragm pumps associated with each supply line. Each supply line may fill corresponding groups of diaphragm pumps with a corresponding ingredient to a supply reservoir for the supply line. Accordingly, different groups of diaphragm pumps corresponding to different supply lines may be filled with corresponding ingredients simultaneously. Those ingredients corresponding to the different groups of diaphragm pumps may also be dispensed simultaneously, giving rise to a faster and more efficient fluidic dispensing system.
Microfluidic Dispensing Assembly

International Classification:

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.
