The vapor phase liquid nitrogen tank is a device used for low-temperature storage of experimental samples such as stem cells, plasma, semen, embryos, various tissues and organs. It can accommodate large quantities of biological samples for long-term static storage, and has both liquid and gas phase storage methods. Compared with traditional liquid nitrogen containers, it is more powerful. Let's talk about the advantages and characteristics of the vapor phase liquid nitrogen freezer in detail. 1. Intelligent supervision: equipped with an intelligent monitoring and management system, it can realize automatic monitoring of the temperature in the tank, abnormal reminders, remote alarms, event recording and automatic rehydration, saving time and effort, safe and reliable. 2. High-density storage: large volume, usually between 350-1800 liters, with higher space utilization, can store a large number of samples. 3. Dual storage mode: provides two modes of liquid phase storage and gas phase storage. The gas phase storage mode uses low-temperature nitrogen evaporated from liquid nitrogen to store samples, avoiding the possible bursting of the cryopreservation tube when it is taken out, and the problem of cross-infection of samples. â?? 4. Stable opening temperature: The unique large-caliber slanted mouth design can reduce liquid nitrogen loss when opening the lid and maintain the stability of internal temperature changes. â?? 5. Temperature monitoring system: The monitoring system can display the temperature inside the tank in real time with high accuracy, and users can set alarm points by themselves. The above are the advantages of stem cell liquid nitrogen tanks, making it an ideal choice for biological sample storage, ensuring the safety of samples and the effectiveness of long-term preservation.

Black Pepper Oleoresin Botanical: Piper nigrum Family: N.O. Piperaceae Hindi Name: Gol Mirch General Description: The best Pepper of commerce comes from Malabar. Pepper is mentioned by Roman writers in the fifth century. The plant can attain a height of 20 or more feet, but for commercial purposes it is restricted to 12 feet. The plant is propagated by cuttings and grown at the base of trees with a rough, prickly bark to support them. Between three or four years after planting they commence fruiting and their productiveness ends about the fifteenth year. The berries are collected as soon as they turn red and before they are quite ripe; they are then dried in the sun. Geographical Sources: Black pepper is native to Malabar, a region in the Western Coast of South India; part of the union state Kerala. It is also grown in Malaysia and Indonesia since about that time when it was found in the Malabar Coast. In the last decades of the 20th century, pepper production increased dramatically as new plantations were founded in Thailand, Vietnam, China and Sri Lanka. The most important producers are India and Indonesia, which together account for about 50% of the whole production volume History/Region of Origin: In South India wild, and in Cochin-China; also cultivated in East and West Indies, Malay Peninsula, Malay Archipelago, Siam, Malabar, etc. Varieties -> in trade, the pepper grades are identified by their origin. In India -> The most important Indian grades are Malabar and Tellicherry (Thalassery). The Malabar grade is regular black pepper with a slightly greenish hue, while Tellicherry is a special product. Both Indian black peppers, but especially the Telicherry grade, are very aromatic and pungent. In the past, Malabar pepper was also traded under names like Goa or Aleppi. Cochin is the pepper trade center in India. In South East Asia, the most reputated proveniences for black pepper are Sarawak in Malaysia and Lampong from Sumatra/Indonesia. Both produce small-fruited black pepper that takes on a greyish colour during storage; both have a less-developed aroma, but Lampong pepper is pretty hot. Sarawak pepper is mild and often described fruity. Description: Oleoresin Black Pepper is the natural extract of dried tender berries of Piper Nigrum Linn of family Piperaceae. Manufacturing Process: It is obtained by the solvent extraction of Black Pepper and the solvent traces are removed by distilling it in vacua at controlled temperature. Physical Appearance: It is a yellowish brown viscous liquid with pungent slightly biting aroma of Black Pepper.
