Retaining the plant stems within the spiral sections, allows secure support without restriction. This gives the plant freedom of movement and encourages air circulation, helping to prevent fungal diseases and promoting strong stem growth. Supporting "Asters to Zinnias" has never been so easy!
Introduction to the components of liquid nitrogen tank
Liquid nitrogen tank products are widely used in animal husbandry, medical and scientific research, mechanical processing, etc., using liquid nitrogen as a refrigerant to preserve animal semen, organs, strains and other biological samples, as well as cryogenic treatment and precision parts of metal materials. Cryogenic assembly.
So what are the specific components of the liquid nitrogen tank? The following will be detailed by Shanghai Bayu technical staff:
Liquid nitrogen tanks are mostly made of aluminum alloy or stainless steel, with 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. The neck of the top is specially designed. The structure must have pores to discharge nitrogen vapor evaporated from liquid nitrogen to ensure safety and heat insulation to minimize the vaporization of 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.
