YDD series gas phase liquid nitrogen tanks, also called stem cell liquid nitrogen tanks, mainly provide users with fully automatic, safe and reliable cryogenic liquid nitrogen storage systems. The tanks are made of high-quality stainless steel and are designed and manufactured in accordance with the national standard GB/T14174-2012. Its mouth adopts a biased mouth structure and has a large capacity. It is suitable for long-term static storage of large quantities of biological products. It has the advantages of large storage capacity of biological products, safe and reliable use, and easy operation.
The overall structure of this series of liquid nitrogen tanks is composed of inner and outer tanks, a rotating tray, a rotating handle, a universal wheel and a plug body cover. Its function is as follows:
Inner and outer bladders: Made of stainless steel, a vacuum interlayer is formed between the inner bladder and the inner bladder to effectively isolate heat transfer.
Rotating tray: Located inside the liquid nitrogen tank, the interior is divided into two spaces, the lower part is the liquid nitrogen storage space, and the upper part is the sample storage space. It can be divided into 4 or 6 areas. Each area is sorted and numbered, and the samples are placed. Easy to distinguish and avoid confusion.
Rotating handle: used to rotate the tray to quickly find samples in different partitions, but you need to wear low-temperature gloves to operate.
Universal wheels: easy to move the tank, two of the casters have fixed functions to prevent the tank from sliding.
Plug body cover: Made of polystyrene material with good thermal insulation performance.

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.
Features: High strength and high corrosionproof, provides long service life and convenient to fill and clean. It provides wide applicability and can be widely applied for packaging in industries such as chemical engineering, petroleum, medicine and food etc. Seal liquid test:Put the sealed barrel with liquid upside down or tap,the seal is at the lowest position,and no leakage within 24 hours. The standard specifies blow-moulding technology requirements of the barrel, test methods and the rules and symbols, packaging, transporting and storage. This standard applies to polyethylene as the main raw material, barrels production through automatic blow molding machine,and this type of blow molding barrel is mainly used for solids or chemical products. We also can help to change any design as your requirements. such as size,weight,color,capacity ect.
