[Prior art]
In general, in a laboratory bench, the above-mentioned laboratory equipment is attached with a belt that can be attached to the shelf member so that the laboratory equipment placed on the shelf member on the laboratory bench does not fall down in the event of an earthquake or the like. It has been proposed to restrain.
[0003]
[Problems to be solved by the invention]
By the way, as described above, when the experimental devices placed on the shelf members on the experimental table are restrained by the belt, the fall is prevented, but if the device is shaken violently, the liquid contained in the devices leaks out. If the liquid drips down below the shelf member in this way, the liquid falls on other laboratory equipment provided immediately below the shelf member, causing damage to the equipment. There is a fear.
[0004]
In view of this, the present invention provides other laboratory equipment directly below the shelf member so that the leaked liquid can be appropriately received even when the liquid leaks from the laboratory equipment placed on the shelf member. It is an object of the present invention to provide an experimental bench that can be protected and that can efficiently process liquid flowing out from a liquid chromatograph analyzer or the like.
