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.

This is chemical setting Furan based chemical resistant mortar which is combination of Liquid and Powder, when mixed in proper proportion from workable mortar which after setting and curing give of liquid and give black highly cross linked composites. Furan When set and cured is resistant to highly corrosive acids, alkalis and to powerful organic solvents such as ketones, Aromatic and Chlorinated solvents. It has extreme resistant to Acidic & alkalis, Salts, Greases and Detergents. It resists to Organic & Inorganic acids at their boiling temperature. It is suitable against mild chlorine Gas (dry) phosphorous trichloride, pyridine at room temperature. Furan is especially useful where resistance to mixed media such as aqueous acids /alkalis and organic solvents is needed in chemical plant process and waste streams. Carbon filled Furan is used against corrosive effect of hydrofluoric acid & its salts. PREPARATION OF FURANE MORTAR : Mortar consist of Furan solution and Furan powder. The average mixing ratio necessary to obtain mortar with good working consistency is 1 part by weight Solution & 3 part by weight powder. The ratio will vary slightly depending on temperature and working conditions.Stir the liquid thoroughly before using. Place liquid in a suitable shallow mixing pan. Add powder by weight in the solution mix thoroughly and rapidly until all lumps are dispersed and the mortar is completely homogenous. Spread out the mortar in a thin layer, not more than ¾ thick, to dissipate the heat of reaction and lengthen the working life. Batch size can be varied depending upon the temperature and the speed with which the masons are working. Very large batches will become stiff quite rapidly. Make sure that all the Furan Motrar is used from the pan before another batch is mixed.When working at temperature above 40 C, very small batches not more than 2 Kgs, should be prepared. When working at temperature below 15C the liquid should be kept warm.
APPLICATION OF SK-HB K-SILICATE MORTAR : * K-SILICATE is used for jointing Acid Resisting brick in construction of vessels in suited for construction of fume chambers and stacks handling hot, dry Acid fumes and vapors. It is also used for jointing chemical resisting stoneware pipes. K-SILICATE cement is good bedding material for Acid â?? Resisting bricks and tiles. The concrete surface needed protection should be dryed, clean and rough. The bricks or tiles will be set with K-SILICATE cement over concrete surface applied with a suitable an impermeable interliner. When Bedding and Jointing Materials are the same. On the treated surface bricks or tiles are bedded to a thickness of about 6 mm and tamp gently with a wooden piece till the paste squeezes out of joints. The paste that is squeezed out of the joint should be removed by trowel with good finishing. After the mortar of the joint is dryed treat the joints with 20% Hydrochloric Acid Solution by means of brush. A.R.lining should be always in contact with Acid and not with water. Concrete subtract like Floor, Wall, tanks and similar surface should be protected with a membrane of Bitrok Mastic or compound steel tanks should be protected with rubber or PVC subjected to chemical conditions and temperature of chemical media. The Brick lining is recommended over the protective layer of Bitrok Mastic. When Bedding and Jointing Materials are Different. Spread the silicate type mortar about 6 to 8 mm thick on the back of the tile or brick. Press the tile on the bed leaving required space for joints between tiles for bricks. After the bedding mortar is set, fill Mp the joints with specified cement.PRODUCT DATA SHEET FOR SK-HB ( K-SILICATE) MORTAR A general purpose cement for acid conditions Resistant to High & medium concentrations of most of the common organic and inorganic acids except Hydroflouric acid. Recommended where the concentration of the acid is high suitable for high temperature. Unsuited to aqueous solutions, alkaline conditions. PREPARATIONS OF MORTAR : * Measure 1 part by weight of K-SILICATE solution into a suitable mixing pan. * Add slowly and gradually 3 parts by weight K-SILICATE mortar and mix thoroughly to form a smooth mortar. * In hot season very large batches of mortar will become stiff quite rapidly therefore small batches, not exceeding 4 to 8 kgs. Will be prepared. * The cement mortar will be used before it starts setting.

* PHOSCAST Phoscast : Phosphate Bonded Castables * PURPOSE customers using FBC boilers (Particularly underbed feed FBC boilers) for the protection of inbed coils against erosion potential by applying highly abrasive resistant refractory on inbed coils above fuel feed system. BACKGROUND * Two of such actions are providing special alloy studs on inbed coils and applying highly abrasive resistant refractory on the outer bottom loops of inbed Coils which are above the fuel feed nozzles. * GANESHAS has taken number of approaches to identify the key factors affecting erosion rates with an objective to enhance the life of inbed tubes as well as implementing the corrective action to reduce the erosion rates. Phosphate coatings are often used to protect steel parts against rusting and other types of corrosion * Erosion of inbed coils in fluid bed combustor is unavoidable phenomenon however the rate of metal wastage and thus the life of tubes depends on various factors like ash & fuel properties, design of Combustor / feeding system, flue gas velocities operating conditions etc. It has been also observed that maximum erosion prone inbed coils are those which come above fuel feed nozzles and an area of approximately 1 to 1.5 mts around fuel feed systems are badly affected. APPLICATION Phoscast-90 XR can be applied by ramming with wooden mallet having adequately large head @" dia x 5" length x 10â?? Jong handle). The desired lining or repair thickness is built up in several courses while ramming the mass to uniform thickness. Phoscast refractory should never be trawled to obtain smooth surface; ramming only should finish surface. Any excess mass is to be sliced off with trowel edge and then finished by ramming again for bed coil. Tube application of AFBC boiler, the material pasty mass should be finger pressed into the studs of the tube with maximum force. Finish should be given by pressing the hand palm against material applied, using surgical type thin rubber hand gloves.
