When using liquid nitrogen tanks, in addition to paying attention to the quality and insulation performance of the tank itself, it is often overlooked, but equally important are its accessories - lifting cylinder, locking cover, and liquid level gauge. Although these components are small, they directly affect the safe storage and efficiency of liquid nitrogen usage.

Firstly, the lifting tube. The lifting tube is used to place sample tubes, making it easy to quickly take and place samples in low-temperature environments. When selecting the lifting tube, the size should be matched according to the liquid nitrogen tank model, and high-strength, low-temperature resistant stainless steel or polymer materials should be prioritized to ensure sample safety and ease of operation.

Next is the lock cover. The lock cover not only prevents liquid nitrogen from evaporating, but also serves as a safety protection to prevent accidental opening or liquid nitrogen splashing. High quality lock covers usually have a sturdy structure and good sealing, and some high-end models also come with lock locks or password lock designs to enhance management and protection functions, especially suitable for laboratory or biological sample storage scenarios.

Finally, there is a liquid level gauge used to measure the remaining amount of liquid nitrogen in the liquid nitrogen tank to prevent dry burning or insufficient liquid nitrogen. When choosing a liquid level gauge, reading accuracy and corrosion resistance should be considered. Common materials include aluminum alloy and stainless steel. Some liquid level gauges are also equipped with electronic display or alarm functions, making them more intelligent and reliable.

Overall, although the accessories of liquid nitrogen tanks may seem inconspicuous, they have a profound impact on the safety and efficiency of daily use. Users should consider their actual needs when making purchases, pay attention to quality and adaptability, and avoid sacrificing big for small gains.
