As we all know, liquid nitrogen tanks are used to store liquid nitrogen and preserve biological samples. They can maximize the low-temperature characteristics of liquid nitrogen. It is used in different industries such as medical research and industrial cold assembly. Small gas phase liquid nitrogen tanks, although also called liquid nitrogen tanks, are very different from traditional liquid nitrogen tanks. Then letâ??s start talking about where they differ. Small gas-liquid phase tank, it is a new type of liquid nitrogen biological container between the YDS series and YDD series. It has the same aviation aluminum material as YDS. The inner and outer tanks are made of the same material. It is relatively light but strong and has good thermal insulation effect. . It also has the same gas-liquid phase dual-mode storage and intelligent management system as YDD; and the only difference between it and traditional liquid nitrogen tanks is the storage mode! Different storage modes There is only one storage mode for traditional liquid nitrogen tanks, which is the liquid phase - the sample is completely immersed in liquid nitrogen. However, this is also its advantage. The temperature of frozen samples is relatively low, the storage time is longer and the maintenance cost is relatively low. However, there are also disadvantages. During use, you must always pay attention to the liquid level in the tank, replenish liquid nitrogen in time, and keep it covering the sample to avoid rapid evaporation of liquid nitrogen that affects sample safety. There are two storage modes for small gas phase tanks, gas phase and liquid phase. The gas phase uses low-temperature nitrogen evaporated from liquid nitrogen to preserve biological samples for a long time. This preservation method does not come into direct contact with liquid nitrogen and can avoid the risk of sample cross-contamination. In the liquid phase, the sample is completely immersed in liquid nitrogen at -196�°C and in direct contact with liquid nitrogen. Two modes can be selected according to different sample requirements. The advantage of gas phase tanks is that they are easy to use and operate, while the disadvantage is that they are more expensive to maintain. Although the storage modes of the two are different, they also have their own merits. When choosing, you can choose a liquid phase or gas phase liquid nitrogen tank based on your own needs.
Mace Botanical: Myristica fragrans Family: N.O. Myristicaceae Hindi Name: Mace - Javitri General Description: Nutmeg, spice consisting of the seed of the Myristica fragrans, a tropical, dioecious evergreen tree native to the Moluccas or Spice Islands of Indonesia. Geographical Sources The nutmeg tree, Myristica fragrans, is indigenous to the Moluccas in Indonesia but has been successfully grown in other Asian countries and in the Caribbean, namely Grenada. Banda Islands, Malayan Archipelago, Molucca Islands, and cultivated in Sumatra, French Guiana Composition -> Nutmeg and mace contain 7 to 14 percent essential oil, the principal components of which are pinene, camphene, and dipentene. Nutmeg on expression yields about 24 to 30 percent fixed oil called nutmeg butter, or oil of mace. Dried kernel of the seed. Varieties -> Whole nutmegs are grouped under three broad quality classifications: 1. Sound: nutmegs which are mainly used for grinding and to a lesser extent for oleoresin extraction. High quality or sound whole nutmegs are traded in grades which refer to their size in numbers of nutmegs per pound: 80s, 110s and 130s (110 to 287 nuts per kg), or 'ABCD' which is an assortment of various sizes. 2. Substandard: nutmegs which are used for grinding, oleoresin extraction and essential oil distillation. Substandard nutmegs are traded as 'sound, shrivelled' which in general have a higher volatile oil content than mature sound nutmegs and are used for grinding, oleoresin extraction and oil distillation; and 'BWP' (broken, wormy and punky) which are mainly used for grinding as volatile oil content generally does not exceed 8%. 3. Distilling: poor quality nutmegs used for essential oil distillation.Distilling grades of nutmegs are of poorer quality: 'BIA' or 'ETEZ' with a volatile oil content of 8% to 10%; and 'BSL' or 'AZWI' which has less shell material and a volatile oil content of 12% to 13%. Method of Processing -> When fully mature it splits in two, exposing a crimson-coloured aril, the mace, surrounding a single shiny, brown seed, the nutmeg. The pulp of the fruit may be eaten locally. After collection, the aril-enveloped nutmegs are conveyed to curing areas where the mace is removed, flattened out, and dried. The nutmegs are dried gradually in the sun and turned twice daily over a period of six to eight weeks. During this time the nutmeg shrinks away from its hard seed coat until the kernels rattle in their shells when shaken. The shell is then broken with a wooden truncheon and the nutmegs are picked out. Dried nutmegs are grayish-brown ovals with furrowed surfaces. Large ones may be about 1.2 inches long and 0.8 inch in diameter. Taste and Aroma: Nutmeg has a characteristic, pleasant fragrance and slightly warm taste
High-speed copper plating of welding wire is brown brown liquid, which is used for non electrodeposition of high-speed copper plating film on iron to facilitate wire drawing process. It can make copper ions deposit orderly, make copper deposit compact, and have strong adhesion. At the same time, the complexing agent can also effectively complexe excessive iron ions in the tank solution, so that the tank solution remains stable. The deposition film is golden yellow and pink, which is loved by users. It can be used as immersion or continuous production line. The weight of copper film is 5-20g/m2

Vapor phase liquid nitrogen freezers are suitable for the cryopreservation of large quantities of biological samples such as stem cells, embryos, vaccines, etc. They are made of low-temperature resistant stainless steel, have large capacity and are easy to operate. They are ideal for large scientific research laboratories and international biological sample banks, providing users with fully automatic, safe and reliable deep-cryogenic liquid nitrogen storage systems. So, do you know the specific advantages and characteristics of liquid nitrogen freezers? 1. Temperature uniformity and stability: The temperature difference of the entire storage area does not exceed 10�°C. During vapor phase storage, the low temperature at the top of the cryopreservation rack can reach -190�°C, which ensures the uniformity and stability of the temperature and is conducive to the long-term preservation of samples. 2. Compatible with vapor phase and liquid phase storage modes: Not only does it support vapor phase storage mode, it is also compatible with liquid phase storage mode. Vapor phase storage uses the low-temperature nitrogen evaporated from liquid nitrogen to store samples, avoiding direct contact between samples and liquid nitrogen, thereby avoiding the problem of bursting tubes and cross-infection of samples when the cryopreservation tubes are taken out, and ensuring the safety of sample storage. â?? 3. Large storage space: The volume ranges from 350-1800 liters, which is much larger than ordinary liquid nitrogen tanks and can store more samples at one time. Its unique slanted mouth design and rotating tray partition access increase space utilization and reduce the storage cost of unit samples. â?? 4. Intelligent management system: Equipped with an intelligent monitoring and management system, it can realize functions such as automatic monitoring of the temperature in the tank, abnormal reminders, remote alarms, and automatic replenishment of liquid nitrogen. â??This system not only improves the convenience of use, but also reduces the cost of manual supervision and ensures the safe storage of samples. In short, the vapor phase liquid nitrogen tank provides an efficient and safe solution for laboratory research and sample preservation through its unique advantages.
