Conventionally, containers with relatively thin walls and approximately equal wall thickness throughout have been used as containers for easily concentrating liquids in physical and chemical experiments, analysis, and drug manufacturing. ing.

困難であという欠点がある。
However, when concentrating a liquid using such a container, there are the following problems. In other words, if the bottom of the container is round, when it is placed on a flat heat source such as a hot plate and heated by heat conduction from the heat source, the thermal efficiency will be poor and it will take time to concentrate. If it is, when the concentration progresses and the liquid volume decreases, a small amount of liquid will spread to the bottom, making it difficult to tell how much liquid is left and making it difficult to remove all the concentrated liquid. There is a drawback.
この考案は、上記の欠点のない液体濃縮容器を
提供することを目的とする。 This invention aims to provide a liquid concentration container that does not have the above-mentioned drawbacks.

That is, the present invention provides a container, the material of which is made of polytetrafluoroethylene,
The inner diameter of the container decreases as it approaches the bottom from the top of the container, a liquid reservoir is provided at the bottom, the wall thickness of the container increases as it approaches the bottom from the top of the container, and This is a liquid concentration container characterized by having a flat bottom.
以下、図面により本考案を説明する。 The present invention will be explained below with reference to the drawings.

発に伴う液体のはい上がりがなく、濃縮後の少量
の液体を全量完全に取り出すことができる特徴を
有する。 1 to 3 show examples of the present invention. In Figures 1 to 3, there is a recess with a fixed volume, that is, a liquid reservoir, at the bottom of the container, so the concentration ratio can be easily determined, and a portion of it can be sampled or the entire amount can be used. The concentration of the target component can be measured by methods such as atomic absorption spectrometry and ICP emission spectroscopy. The size may be arbitrary depending on the purpose of use. The larger the diameter to height ratio is, the more advantageous it is in terms of concentration rate, but it is usually 1:1 to 5:1.
It is preferable in terms of handling. The material of the container is polytetrafluoroethylene (commonly known as Teflon, a registered trademark of DuPont). Since polytetrafluoroethylene has excellent water repellency, there is no liquid leakage caused by evaporation of the solution, and the small amount of liquid after concentration can be completely taken out.
該容器の内壁は、液体のはい上がりがおこらな
いように滑らかな仕上げとすることが好ましい。 The inner wall of the container preferably has a smooth finish to prevent liquid from seeping up.
該容器底面は、凹凸のない平面になつていなけ
ればならない。 The bottom of the container must be flat and smooth.
容器の内径が底に近ずくにつれて小さくなつて
いるため、濃縮が進んで液量が少なくなつたとき
にも液の残量がわかりやすく、また、底が平らに
なつているために、ホツトプレートなど平らな熱

が速くできる。
Since the inner diameter of the container decreases as it approaches the bottom, it is easy to see how much liquid is left even when concentration progresses and the liquid volume decreases.Also, since the bottom is flat, the hot plate When condensing by placing it on a flat heat source such as a flat heat source, it has good thermal efficiency and can concentrate quickly.
