Abstract

The invention discloses a high-precision multi-plunger row pipetting device which comprises a bracket, a first lifting mechanism arranged on the bracket, and a first lifting mounting frame with a U-shaped structure, a second lifting mechanism is arranged on the first lifting mounting frame and is provided with a lifting plate positioned between an upper plate and a lower plate of the first lifting mounting frame; the plunger pumps are located between the lifting plate and the lower plate, and gun head adapters extending below the lower plate are integrally arranged at the outlet ends of the plunger pumps; the puncturing heads are arranged near the gun head adapters, the tops of the puncturing heads are connected with the lower plate, and the bottoms of the puncturing heads are of sharp thorn structures used for opening reagent sealing films; and the gun head withdrawing mechanism comprises a push plate arranged below the lower plate, a push rod penetrating through the lower plate and extending upwards is arranged on the push plate, a limiting piece located below the lifting plate is arranged at the top of the push rod, and an elastic return piece is arranged between the limiting piece and the lower plate. The liquid transfer device is ingenious in design, reliable in quality, high in liquid transfer precision, good in sealing effect and free of liquid leakage after long-term operation.

Description

technical field [0001] The invention relates to the technical field of in vitro diagnostic testing equipment, in particular to a high-precision multi-plunger serial pipetting device. Background technique [0002] In vitro diagnostic testing is a technology that uses modern physical and chemical methods and means for medical diagnosis. It mainly studies how to provide evidence for clinical diagnosis and treatment through laboratory technology and medical equipment. This technology requires the use of various photoelectric instruments and chemical reagents to complete experiments. analyze. As we all know, the plunger pump is a device that uses the plunger to reciprocate in the pump chamber to change the volume formed in the pump chamber and repeatedly suck and discharge liquid; in medical, chemical and other laboratories, plunger pumps are usually used to absorb And add different amounts of reagents and samples, and inject them into the reaction pool for chemical reaction.
