- a plurality of samples are accommodated in the cell s composed of 3) without mixing with each other, so that, for example, various analysis and culture of DNA can be performed.
- the plate-shaped substrate (34) is formed of a resin material such as a polystyrene resin, or various kinds of glass such as soda lime glass, or an inorganic material such as various kinds of ceramics or various kinds of metals.
- the lower surface side gradually narrows.
- the truncated conical through-holes (27) are arranged in rows and columns on the lower surface side, and more than 80% of each through-hole (27) is provided.
- the bottom side is made of natural quartz glass with high UV transmittance, synthetic quartz glass, borosilicate glass, and other UV-permeable glass. Glass container (35) is fixed.
- the glass plate is formed into a glass container molded body (36) in which a large number of glass containers (35) are integrally formed on the negative side by a vacuum molding method or the like. (3 6) is superimposed on the plate-shaped substrate (34) so that each glass container (3 5) enters each through hole (2 7), and is joined with an inorganic or organic adhesive (22). I have.
- the inner surface of the cell s is easily cleaned, which is suitable for repeated use.
- FIG. 9 shows a modification of the seventh embodiment, in which an inorganic material such as various ceramics and various metals is formed into a substantially rectangular shape as a whole, and gradually narrows toward the lower surface, that is, the diameter decreases toward the lower surface.
- a heat-softened UV-transparent glass plate (37) is vacuum-molded on a plate-shaped base material (34) in which truncated conical through holes (27) are juxtaposed vertically and horizontally. And the like, so as to penetrate into each of the through holes (27) so as to be integrated into the through hole (27) and to be integrally fired over one side surface of the plate-shaped substrate (34) and the inner peripheral surface of the through hole (27).
- an ultraviolet-permeable glass container (35) is inserted, and the outer peripheral surface of the glass container (35) is brought into close contact with the inner peripheral surface of the through hole (27). And fixed.
- FIG. 10 shows a modification of the seventh embodiment or the eighth embodiment.
- the plate-like base material (34) is formed of a thin plate material.
- a through hole (27) is formed inside the cylindrical wall (38).
- the external shape is merely an example of a so-called plate-shaped biochemical container.
- the external shape may be any number as long as a plurality of cells s are formed. It is not limited to a plate.
- the biochemical container according to the present invention as described so far Since the bottom surface of the cell s is flat, in particular, visible light, ultraviolet light, or X-rays for spectrometry are incident on the bottom side of the biochemical container, such as a microplate reader, in the vertical direction. When measuring the transmitted light, the measurement can be performed with high accuracy, which is advantageous.
- the biochemical container according to the present invention can accommodate not only the sample of the organic solvent but also various liquid samples such as an aqueous solution in the cell s.
- the spectroscopic measurement means a measurement using transmitted light or reflected light such as ultraviolet light, visible light, fluorescence, X-rays, and the like.
- a separately molded ultraviolet-permeable glass container (35) is inserted into each of the through holes (27), and the glass container (3 The outer peripheral surface of 5) may be closely fixed to the inner peripheral surface of the through hole (27) by bonding.
- biochemical container that has high resistance to organic solvents, can be easily manufactured, and can perform ultraviolet spectroscopic measurement.
- the biochemical container according to the present invention can be suitably used, for example, as a measurement plate of a microplate reader.
