What we present to you is a liquid nitrogen container designed for laboratory sample storage. It is made of special aviation aluminum material. It not only has a low liquid nitrogen volatility rate, but also has the advantages of lightweight and space saving. It is suitable for efficient storage of large-capacity samples. Whether you are a scientific researcher or an industrial user, our laboratory liquid nitrogen tank can meet your different needs. Product Features: Large capacity selection: A variety of volume options from 30 liters to 175 liters, which can accommodate 750 to 6000 2ml or 540 to 1800 5ml cryotubes. High efficiency and energy saving: The high-strength and lightweight aluminum structure is combined with a multi-layer insulation vacuum design to effectively reduce thermal radiation and liquid nitrogen loss. Friendly operation: The large-caliber design facilitates sample placement and removal, and the high-strength neck tube design further reduces liquid nitrogen consumption. Safety guarantee: The optional safety lock and the vacuum warranty period of up to five years make you feel more at ease when storing samples. Intelligent management: The laboratory liquid nitrogen tank supports the optional intelligent monitoring system to realize remote monitoring function and keep track of the status of the tank at any time. Liquid nitrogen automatic transfer solution: In order to facilitate the transfer of liquid nitrogen, we provide two types of liquid nitrogen automatic transfer pumps for you to choose from: foot-operated (TCLNP-50) and mechanical (TCLNP-50A). Both are made of stainless steel pump body, with exquisite appearance, durable and easy to use, suitable for 50mm caliber liquid nitrogen tanks. Among them, the foot-operated liquid nitrogen pump is also equipped with a hand-pump and double thickened cylinders, making liquid nitrogen transfer easy and labor-saving; the mechanical liquid nitrogen pump has a normal version and a version with wireless remote control to choose from, and the one-button power on and off design makes the operation easier. Choosing our laboratory liquid nitrogen tanks and supporting equipment will bring more convenience and efficiency to your scientific research work.
