Embodiment Construction

[0036] The present invention will be described in detail below.

[0037] Figure 1A And Figure B is a schematic structural diagram of an example of the filling device of the present invention, Figure 1A The symbol 1 in is the filling device of the liquid (hereinafter referred to as the filling device).

[0038] The filling device 1 is composed of a discharge head 2 , a container 3 storing a liquid substance to be discharged, and a pressure controller 4 provided with a suction device for sucking the liquid substance in the discharge head 2 .

[0039] Extrusion head 2 such as Figure 2A As shown, for example, a nozzle plate 12 and a vibrating plate 13 made of stainless steel are provided, and both are joined by a partition member (tank partition) 14 . Between the nozzle plate 12 and the vibrating plate 13 are formed compartments 15 .

[0040] The interior of each compartment 15 and the container 16 is filled with a liquid substance, and the flow path 17 between them functions...

Abstract

Provided is a filling method of liquid, and a filling device for liquid, as well as a discharge device. The filling device for liquid is provided with a cavity for storing a liquid L, a nozzle communicating with the cavity, and a discharge head 2 with a discharge means for discharging the liquid L stored in the cavity through the nozzle. Furthermore, the filling device 1 of the liquid is provided with a feeding part 3 of the liquid for feeding the liquid L to the nozzle of the discharge head 2 so as to bring the liquid into contact with the nozzle, and a suction means 4, connected to the cavity side of the discharge head 2, for aspirating the liquid fed from the feeding part 3 of the liquid into the cavity by aspirating the liquid through the nozzle via the cavity.

Description

technical field [0001] The present invention relates to a method and a device for filling a liquid substance at a desired position, especially a filling method and a liquid substance filling device for filling expensive reagents and rare specimens, and a sprayer equipped with such a filling device. out of the device. Background technique [0002] In recent years, the analysis methods of genetic structure have made remarkable progress, and the structure of many genetic genes has been revealed, including human genetics. In the analysis of such a genetic structure, thousands to more than 10,000 different types of DNA fragments are used as observation points on substrates such as microscope glass slides, and after being arranged and fixed as objects to be examined, microscopes, etc. The method of observing it, etc. [0003] However, when the number of such objects to be inspected is thousands or more, since all operations are performed manually, the efficiency is extremely poo...
