Description

[Detailed Description of the Invention] This invention relates to an aspirator-equipped experimental bench that houses an aspirator for sucking air used for various experiments.

Aspirators conventionally used in various experiments are
It is very inconvenient as it requires space because it is placed on the laboratory table like other experimental tools. Also,
An aspirator in which casters are provided at the bottom of the main body has the disadvantage that it takes up space and is very troublesome to move during use and to switch and connect the power source. In addition, both the stationary type and the mobile type are difficult to manufacture in large sizes that require a large amount of water due to space constraints.

This invention improves each of the above-mentioned drawbacks, and its main structure is that a longitudinal storage chamber is formed with a partition wall at the bottom of the center of the interior of the experimental bench. An aspirator body equipped with several circulation pumps is installed, and
Suction ports were protruded from several locations on the side wall of the experimental bench, and several aspirators connected to the water pump of the aspirator body were connected to the suction ports via suction hoses. Therefore, according to this invention, the space in the laboratory where the aspirator is equipped and on the laboratory bench can be used significantly, and since the aspirator body is installed using the space in the center of the laboratory bench, it does not get in the way. Moreover, since the aspirator main body can be made large, it has the excellent effect of preventing a rise in water temperature as much as possible and eliminating the need for a cooling device.

Next, an embodiment of this invention will be explained with reference to the drawings. Partition walls 3, 3 facing each other in the longitudinal direction are installed at the bottom of the center of the inside of the experimental table 1 of various shapes, and a longitudinal storage chamber 2 is formed inside. urge In this longitudinal storage chamber 2, an aspirator main body 4 equipped with several circulation pumps 7, 7 is installed. Next, the experimental table 1
There are suction ports 6, 6 in several places on the side wall 5 that is not used.
is installed in a protruding state. The aspirator 8 installed in the circulation pumps 7, 7 is made of metal or synthetic resin such as Teflon, and an intake hose 9, 9 made of rubber or the like is connected to one end of the aspirator 8. The other end is connected to the suction ports 6, 6 provided on the side walls 5, 5. A connecting hose 10 is connected to the suction valves 6, 6, and its tip is connected to various experimental equipment for use. 1
1 is a sink for washing, 12 is a faucet, and 13 is a motor installed in the aspirator body 4.

This device has the above-mentioned configuration, and in order to use the aspirator of this device, the hose connected to the suction ports 6, 6 provided on the side walls 5, 5 of the experimental table 1 must be
0, and the other end is connected to a device such as a rotary evaporator, and the circulation pump 13 is operated by operating a switch (not shown) provided at an arbitrary position on the side wall 5, etc., thereby rotating the circulation pump. The water inside is circulated through the aspirator 8 by the pumps 7, 7, and the water is quickly sucked from the inside of each hose to exhaust the air inside each device.

Since this idea is as described above, it does not require space for installing aspirators on various experimental benches or on the floor, and has the effect of making it possible to use a large amount of space in various places.
It has the advantage of being very convenient since it does not require the trouble of placing it on the table or transporting it. Since a longitudinal storage chamber is formed with a partition wall at the bottom of the center of the inside of the experimental table, the aspirator body can be installed securely and stably, and since it is not exposed to the outside, it has an excellent effect of not getting in the way. Since even a large aspirator main body can be installed in the storage room, the amount of water in the water tank can be increased, and a rise in temperature can be prevented as much as possible, thus making it possible to eliminate the need for a cooling device. In addition, since several suction ports are installed on the side walls of the experimental table, they are very convenient to use and have the excellent effect of not getting in the way.
