What are the specific classifications of liquid nitrogen tanks and the components of liquid nitrogen tanks? The following will be detailed by Shanghai Bayu technical staff: First, liquid nitrogen tank classification 1. Liquid nitrogen biological container is referred to as liquid nitrogen tank. According to the national recommended standard of GB/T5458-1997 : liquid nitrogen tank is divided into liquid nitrogen storage tank, liquid nitrogen storage tank and self-pressurized liquid nitrogen container according to the use. Liquid nitrogen storage tank (storage type): The liquid nitrogen storage time is long, and it is suitable for long-term preservation of active biological materials in the standing room. 2 , according to the volume classification: storage liquid nitrogen container from large to small: 2L , 3L , 5L , 6L , 10L , 15L , 20L , 30L , 35L transport and storage dual-use liquid nitrogen biological containers from large to small: 10L , 15L , 30L , 35L , 50L , 100L self-pressurized liquid nitrogen containers: 50L , 100L , 175L , 200L , 300L , 500L are classified according to their caliber: 35mm , 50mm , 80mm , 125mm , 500mm . Second, liquid nitrogen tank construction Structurally speaking, the liquid nitrogen tank is mostly made of aluminum alloy or stainless steel, and is divided into two layers inside and outside. The specific components are as follows: 1. Shell: The outer layer of the liquid nitrogen tank is the outer shell, and the upper part is the tank mouth. 2 , inner tank: the inner space of the liquid nitrogen tank is called the inner tank, generally the corrosion-resistant aluminum alloy, the bottom of the inner tank has a base for the fixed lifting cylinder, the liquid nitrogen and the sample can be stored in the inner tank in. 3. Interlayer: The interlayer refers to the gap between the inner and outer layers of the tank . It is in a vacuum state. The purpose of vacuuming is to improve the thermal insulation performance of the can, while the interlayer is provided with a heat insulating material and an adsorbent. 4 , neck tube: the neck tube is usually FRP material, the inner and outer layers are connected and kept to a certain length, and the adsorbent is installed around the neck tube and the bottom layer. Special design of the top of the neck, which both have pore structures can be discharged out of the liquid nitrogen evaporated nitrogen in order to ensure safety, but also a heat insulating property, to minimize the amount of vaporized liquid nitrogen. 5 , the stopper: the stopper is made of plastic with good heat insulation to prevent the evaporation of liquid nitrogen, and at the same time fix the handle of the lifting cylinder. 6. Lifting the bucket: The lifting cylinder is placed in the tank inner tank, in which the thin tube can be stored. The handle of the lifting cylinder is hung on the neck and fixed with a stopper.
