Description

[Detailed Description of the Invention] The present invention relates to the structure of an electrolytic beaker used when dissolving a sample that requires high analytical accuracy.

When heating and melting samples that require high analysis precision, such as analytical standard samples, for example, as specified in JISH1101, a flat bottom surface with good thermal efficiency prevents the sample inside from escaping as mist. To prevent this, an electrolytic beaker is used that has a ground lid and a wide mouth that makes it easy to wash out the dissolved sample.

When using such an electrolytic beaker, the mist generated during melting will adhere to the joint area of the lid, so the sample that adheres to this area after melting will be
It gets stuck in the joints and is difficult to wash out, and in addition, the washing operation to pour the washing liquid into the beaker to prevent it from spilling is complicated and requires careful attention, which causes a decrease in the sample recovery rate in practice. This made high-precision analysis difficult.

In order to eliminate these difficulties, the present invention eliminates the grinding part of conventional electrolytic beakers to facilitate cleaning operations, and also provides a double lid to prevent sample escape, allowing for high-precision analysis. The present invention provides an electrolytic beaker that enables

An embodiment of the present invention will be explained with reference to FIG.

FIG. 1 shows an embodiment of the present invention having an upper part 1 having a large inner diameter, a lower part 2 having a small inner diameter, a connecting part 3, and a structure in which lids 5 and 6 can be installed inside and at the top, respectively. This allows the inside of the beaker to
There will be a double lid on top of and the top 4.

When a sample is dissolved using the beaker of the present invention, a portion of the sample inside the beaker scatters as mist, but most of it adheres to the inner lid 5 and refluxes.
Furthermore, the mist that has escaped through the gap in the inner lid 5 also adheres to the upper lid 6 and the upper wall surface 1 and is refluxed.
Samples adhering to the wall surface can be easily cleaned because the opening 4 is wide, and since smooth glass can be used for the top and inner lids, cleaning can be done easily and quickly. Therefore, the cleaning liquid will not be spilled or left on the wall surface. Therefore, according to the present invention, it is easy to perform analysis with a high accuracy of 99.99% or more. Furthermore, a watch glass may be used on the inner lid 5 to facilitate handling and cleaning of the lid.
