- the solvent may evaporate from the opening, and the solvent may be reduced.
- the opening was closed by a lid 52, and when dispensing the liquid in the tank 50 with a tip 51, the lid 52 was removed and used.
- the lid 52 of this type can not seal the tank 50 and can not prevent the loss of the organic solvent by volatilization. If the organic solvent in the tank 50 is depleted, the solvent injected first is reduced, which causes a problem that the result of quantitative analysis can not be accurately obtained. In recent years, as the technology of microanalysis has developed, the influence of volatilization of the solvent in the container on the analysis results is considered to be particularly large. In addition, it is necessary to attach and detach the lid 52 every time the dispensing operation is performed, and as a result, there is a problem that the operation efficiency of the dispensing and the subsequent test decreases.
- the pipette tip 51 itself is made of a resin that is more resistant to friction than a metal tip, so-called septum is used in consideration of the tightness of the tank. Thought However, since the septum itself can only penetrate a metal tip (needle), it can not withstand multiple extractions and is impossible to adopt.

If the number of insertion and removal of the chip 51 is large and the number of chips 51 is two or more, the wear around the slit 54 becomes remarkable, and the slit 54 itself is not opened and sealed, resulting in volatilization of the liquid. It can not be prevented and it can not prevent the loss of liquid in the tank.

- the same operation was performed without making a cut in the sheet made of the same material (hereinafter referred to as the closed type). Furthermore, without placing the sheet on top, it was left as it is in a 37 ° C. constant temperature bath (hereinafter referred to as lidless! / ⁇ ⁇ ).
- the results are shown in Table 3.
- the numbers in Table 3 represent the amount of water remaining in the tank as a percentage by volume relative to the volume initially placed, as a percentage by volume.
- the results are shown in FIG. FIG. 13 is a graph showing the results of the volatility test when the sheet was placed on the container. In the graph, the horizontal axis represents time, and the vertical axis represents the amount remaining in the container.
- FIG. 1 It is an exploded perspective view explaining the container for liquid in and out.
- FIG. 4 is an explanatory view showing another example of a slit.
- FIG. 5 is a cross-sectional view of the sheet of the present invention.
- FIG. 6 is an explanatory view showing another example of a slit.
- FIG. 9 An explanatory view of a base plate provided with an elastic member for preventing lifting.
- FIG. 10 An explanatory view of a base plate with a screw for preventing lifting. 11] It is an explanatory view of a base plate in which a groove is formed on the contact surface.
- FIG. 15 is an explanatory view of a conventional closed tank.
