Embodiment Construction

[0011] like figure 1 Among them, a liquid nitrogen tank includes a tank body 1 with an open upper end, an outlet pipe 6 connected to the tank body 1, a sealing valve 4 is installed at the outlet end of the outlet pipe 6, and a first sealing valve is installed at the opening 7 of the tank body 1. Cover 2, the first sealing cover 2 is provided with a sealing cover opening 8, the second sealing cover 3 is installed on the sealing cover opening 8, the size of the second sealing cover 3 is smaller than the size of the first sealing cover 2, and the tank body 1 is also Handle 5 is installed.

[0012] The sealing valve 4 is wrapped with an antifreeze layer, and the antifreeze layer is a cotton cloth layer.

[0013] The handle 5 is wrapped with an antifreeze layer, and the antifreeze layer is a cotton cloth layer.

[0014] The first sealing cover 2 and the second sealing cover 3 are circular covers, the diameter of the second sealing cover 3 is 4-6 cm, and the second sealing cover 3...

Abstract

A liquid nitrogen tank comprises a tank body with an open upper end; the tank body is communicated with an outlet pipe; a sealing valve is arranged at the outlet end of the outlet pipe; a first sealing cover is arranged at the opening position of the tank body; a sealing cover opening is formed in the first sealing cover; a second sealing cover is arranged on the sealing cover opening; the size ofthe second sealing cover is less than that of the first sealing cover; and a handle is arranged on the tank body. The liquid nitrogen tank provided by the invention can solve the problems of being inconvenient to use, not safe, and easy to cause waste, can control the use amount well, avoids waste of liquid nitrogen, is safe to use and avoids damage to experimenters caused by the phenomenon thatthe liquid nitrogen is splashed.

Description

technical field [0001] The invention relates to the technical field of experimental equipment, in particular to a liquid nitrogen tank for molecular biology experiments. Background technique [0002] In molecular biology experiments, liquid nitrogen is used whether it is extracting DNA, RNA, or storing samples. However, the liquid nitrogen tanks currently used in laboratories are large and heavy, and only one nitrogen outlet is opened on the upper end of the tank. It is very inconvenient to use, and liquid nitrogen will splash out during the pouring process, causing waste and injury to experimenters. When extracting RNA in the laboratory, it is necessary to pour liquid nitrogen into the grinding bowl while grinding the sample. Usually, two people are required to conduct the experiment, resulting in a waste of manpower. In the process of taking the sample, when the sample is put into the liquid nitrogen tank, because the sample will release heat, the liquid nitrogen will spl...
