DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shelf device provided on a laboratory bench, and more particularly to a system capable of coping with a case where liquid leaks from laboratory equipment mounted on a shelf member and performing high-speed chromatography. TECHNICAL FIELD The present invention relates to a laboratory equipment mounting shelf apparatus which can also achieve convenience in using a graph analyzer or the like.

[0002]

2. Description of the Related Art In general, a laboratory table is provided with a belt whose tip is attached to the shelf member so that experimental equipment mounted on the shelf member on the bench does not fall down in the event of an earthquake or the like. It has been proposed to restrain laboratory equipment.

[0003]

As described above, if the laboratory equipment placed on the shelf member on the laboratory table is restrained by the belt, the equipment is prevented from falling down. There is a possibility that the liquid contained in the equipment leaks, and when the liquid drips down below the shelf member in this manner, the liquid falls on other laboratory equipment provided immediately below the shelf member. This may cause damage to the equipment.

[0004] Therefore, the present invention has been made to solve the problem that even if a liquid leaks from laboratory equipment mounted on a shelf member, the leaked liquid can be properly received and another experimental device directly below the shelf member can be received. An object of the present invention is to provide a laboratory equipment mounting shelf apparatus which can protect equipment and can efficiently treat liquid flowing out of a liquid chromatograph analyzer or the like.

[0005]

In order to solve the above-mentioned problems, the present invention provides a laboratory equipment mounting shelf apparatus comprising: a shelf member for mounting laboratory equipment containing liquid; A through hole for introducing the liquid leaked from the equipment onto the shelf member is formed on the upper surface of the shelf member, and a container for receiving the liquid flowing into the through hole and falling therethrough is provided below the shelf member. It is characterized by being provided on the side.
