Filter-carrying micro plate

Abstract

There is provided a filter-equipped microplate including: an upper container 41 having openings 50 for injection of a substance to be tested; a top packing 44 and a bottom packing 45 that hold filters 46; a middle container 42 that fits with the upper container 41 and has openings 63 through which a test sample that has passed through the filters 46 runs, and that clamps the top packing 44 and the bottom packing 45 against the upper container 41: and a lower container 43 having reservoirs 80 that retain the test sample, the lower container 43 being held in a freely detachable manner against the middle container 42, wherein the middle container 42 has guide walls 64 that suspend down from the openings 63 and provide downward openings 65 to the bottom end, and the reservoirs 80 in the lower container 43 house the guide walls 64, the reservoirs 80 receiving the test sample supplied from the downward openings 65 of the guide walls 64 through the filters 46, and the lower container 43 having vents 90 at a widening slant 92 at the top, that communicate with the outside of the reservoirs 80.

Description

technical field [0001] The invention of the present application relates to a microplate with a filter. More specifically, it relates to a microplate incorporating a filter having a structure in which a substance to be tested passes through the filter, a filtered test sample is collected in a storage part, and the storage part can be easily separated . Microplates with filters are widely used in cell tissue culture or bioculture tissue inspection and other fields. Background technique [0002] In the microplate with a filter, components that hinder the detection sensitivity are separated from the test substance through the filter in advance, that is, filtered to obtain only the components that are useful for the desired culture purpose or test. This is because, when unnecessary components are mixed, there are problems in that excessively unwanted peaks appear, making it difficult to identify a targeted peak point, or that an originally intended peak point does not respond a...

Problems solved by technology

Although these elements need to be assembled quickly and in a clean state, in these known microplates, the focus is mainly on the development of filters, and it is difficult to quickly and hygienically assemble the elements constituting the microplate

In addition, the microplate generally uses a very thin and easily broken filter. Therefore, during the movement of the microplate, the position of the filter changes from time to time, resulting in an accident of damage.

In addition, when filtering the substance to be inspected, depending on the content of the inspection, it is sometimes required that the mesh of the filter be formed very finely, but in this case, there is a problem that it takes a long time for the substance to be inspected to pass through the filter

Furthermore, in the case of microplates, it is very difficult to stack multiple microplates when multiple microplates are required to examine multiple specimens.

[0010] Moreover, the sample in the storage part may be mixed with the sample in the adjacent storage part during the inspection suction, and when a large negative pressure is applied during the inspection suction, the sample may flow backward. The problem that the sample may flow out of the storage part during suction
