Fluid dispensing system

摘要

Fluid Dispensing System Abstract An apparatus (100) including a fluid reservoir (102) and a compressible metering chamber (110) including a first end coupled to the fluid reservoir (102) and a second end. The apparatus (100) further including a valve (118) coupled to the second end of the metering chamber (110) and a nozzle (120) coupled to the valve (118). A system including linearly translatable cartridge mounting assembly (1702) having a plurality of fluid dispensing cartridge mounting stations (1704) and a plurality of fluid dispensing cartridges (1706) mounted to respective fluid dispensing cartridge mounting stations (1704). The system further including a plurality of compression assemblies (1906) coupled to respective fluid dispensing cartridges (1902) and a receiving assembly positioned beneath the mounting assembly (1904). A method includes positioning a fluid dispensing cartridge (100) comprising a fluid reservoir (102) and a metering chamber (110) over a sample retaining member, applying a compressive force to the metering chamber (110) to eject a predetermined amount of fluid and removing the compressive force to refill the metering chamber (110).
