ABSTRACT:
The invention is a hydraulic dispenser and a method for hydraulically dispensing sample liquids. The hydraulic dispenser acts as a hydraulic press to dispense sample liquids from an insertable magazine. The hydraulic dispenser includes a hydraulic pump hydraulically connected to a magazine coupler. The magazine acts as a store for the sample fluid and is inserted into the hydraulic dispenser and connected to the magazine coupler. If the magazine is disposable, it may be unloaded from the hydraulic dispenser and discarded after usage. The hydraulic pump can generate quantitative positive displacements of hydraulic liquid which are transmitted to the magazine coupler. The magazine coupler responds to the hydraulic displacements from the hydraulic pump by collapsing and expanding the magazine inserted therein and thereby expressing and aspirating sample liquid. A hydraulic dispenser loaded with a magazine can express sample liquid from the magazine by quantitative positive hydraulic displacement generated by the hydraulic pump. The invention combines the principle of the hydraulic press with the concept of an insertable magazine in order to dispense sample liquids by quantitative positive hydraulic displacement. The hydraulic press imparts accuracy; the insertable magazine imparts disposability and convenience.
