In the modern laboratory environment that pursues precision and efficiency, proper storage of samples and safe transportation of liquid nitrogen are very important. We hereby launch a combination of liquid nitrogen tanks and liquid nitrogen pumps designed specifically for laboratory sample storage, aiming to provide strong support for your scientific research. The liquid nitrogen dewar used for cell storage is made of high-quality aviation aluminum, combined with a multi-layer insulation vacuum design, which not only achieves an ultra-low liquid nitrogen volatility rate, but also ensures lightness and durability. Its large-caliber design makes sample storage and access more convenient. The large capacity of 30-175L can meet the needs of laboratories of different sizes, and can accommodate up to 6,000 2ml cryotubes or 1,800 5ml cryotubes. The standard cryo racks and cryo boxes, plus the safety lock cover and the optional intelligent monitoring system, together constitute an efficient and safe storage environment. For liquid nitrogen pumps, we provide two options: The mechanical liquid nitrogen pump integrates pressure measurement and display control functions, can realize intelligent management, one-button start/shutdown, and adapts to a variety of application scenarios, such as small amounts of liquid nitrogen transfer tasks in the medical and scientific research fields. The pedal-operated liquid nitrogen pump, with its unique double-thickened cylinder design, ensures high efficiency and stability during the liquid nitrogen transfer process. Both use stainless steel pump bodies, which are beautiful, durable and easy to operate. Whether it is a large research institution pursuing extreme performance or a small laboratory focusing on cost-effectiveness, our liquid nitrogen cell storage tank and liquid nitrogen pump combination can provide you with a satisfactory solution.
