Interchangeable liquid dispensing cartridge pump |
摘要 |
A liquid dispensing cartridge pump suitable for dispensing reagent in an automatic system includes a compressible metering chamber suspended from a reservoir bag mounted within a rigid housing. Check valves between the reservoir and metering chamber and at a lower end of a metering chamber are formed of flexible membranes having apertures which close against conical projections on rigid disks. The reservoir and metering chamber pivot as a compression member squeezes the metering chamber against a back surface.
