Abstract

An apparatus including a fluid reservoir and a compressible metering chamber including a first end coupled to the fluid reservoir and a second end. The apparatus further including a valve coupled to the second end of the metering chamber and a nozzle coupled to the valve. A system including linearly translatable cartridge mounting assembly having a plurality of fluid dispensing cartridge mounting stations and a plurality of fluid dispensing cartridges mounted to respective fluid dispensing cartridge mounting stations. The system further including a plurality of compression assemblies coupled to respective fluid dispensing cartridges and a receiving assembly positioned beneath the mounting assembly. A method includes positioning a fluid dispensing cartridge comprising a fluid reservoir and a metering chamber over a sample retaining member, applying a compressive force to the metering chamber to eject a predetermined amount of fluid and removing the compressive force to refill the metering chamber.
