Large caliber square bucket liquid nitrogen tank

The YDS-175-216 large caliber square bucket liquid nitrogen tank is a device specially designed for long-term storage of biological samples and frequent extraction scenarios. Combining the two core advantages of low liquid nitrogen consumption and medium range freezing tube capacity, it has become a product for small sample libraries and early stages of library construction due to its light weight and small footprint. The following is a detailed product parameter introduction, with accurate and easy to understand data that fully corresponds to the five performance characteristics of the product. It presents the practicality and economy of the equipment clearly, making it convenient for users to quickly understand product configuration, selection reference, and daily use reference.

1、 Core Basic Parameters

1. Model and specification: YDS-175-216 (large caliber square bucket series), belonging to the medium-sized and large capacity liquid nitrogen tank, focusing on "convenient access+low consumption and practicality", suitable for small sample libraries, early stages of library construction, and various high-frequency sample access scenarios, without complex operations, making it easy for beginners to get started;

2. Geometric volume of the tank: 175L, the effective volume can fully adapt to the capacity of medium range cryovials, without the need for additional storage equipment, which can meet the batch storage needs of small sample warehouses. At the same time, it can be compatible with various specifications of sample containers such as ampoules and cryovials, and has a wide range of adaptability;

3. Tank body diameter: 216mm, continuing the core design of a large diameter, paired with a dedicated bucket for use, greatly expanding the operating space, facilitating sample retrieval and storage, and overall extraction from the freezer rack, effectively reducing the probability of sample container collision and damage during retrieval and storage, and improving operational efficiency;

4. Empty tank weight: ≤ 58kg, built with high-strength and lightweight aluminum structure. Compared with traditional liquid nitrogen tanks of the same capacity, it is lighter and can be easily moved and placed by a single person without the need for multiple people to cooperate. It is suitable for small storage spaces and does not require a large area to be specifically set aside for equipment placement.

2、 Key performance parameters

1. Vacuum performance: Adopting a high vacuum multi-layer insulation structure, a high vacuum interlayer is set between the inner and outer tanks of the tank. The interlayer is filled with high-quality adsorbent, which can effectively block external heat conduction, firmly lock the low-temperature environment inside the tank, and ensure long-term stability of the vacuum degree. The manufacturer solemnly provides a 5-year vacuum guarantee. During the warranty period, if the equipment has quality problems such as vacuum decay or leakage, relevant components can be repaired or replaced free of charge without the user bearing any repair costs. This solves the user's long-term worries and provides a core guarantee for the long-term stable storage of samples;

2. Liquid nitrogen consumption parameters: Adhering to the core advantage of low liquid nitrogen consumption, the daily evaporation of static liquid nitrogen is ≤ 1.3L, the storage period of static liquid nitrogen is ≥ 135 days, and it can be stably used for more than 4 and a half months after filling with liquid nitrogen once, without the need for frequent replenishment of liquid nitrogen, greatly reducing the cost of liquid nitrogen consumables. Compared to traditional large-diameter liquid nitrogen tanks, its liquid nitrogen evaporation rate is reduced by more than 30%. Long term use can save a lot of operating costs, especially suitable for small sample libraries with limited budgets and in the early stages of library construction;

3. Safety configuration parameters: Equipped with a standard safety lock cover and a convenient locking design, the lock is firm and the switch is flexible. It will not affect the efficiency of sample collection and placement, but can effectively prevent accidental opening of the tank cover, avoid liquid nitrogen leakage, frostbite to personnel, and environmental pollution. At the same time, it can block unrelated personnel from contacting the sample, prevent sample loss, accidental contact, or pollution, and protect the safety of the sample and operators.

3、 Structure and adaptation parameters

1. Tank material: Made of high-strength anti rust aluminum alloy, specially treated for corrosion and low temperature resistance, with a sturdy and durable texture that can withstand slight collisions during daily operation, is not easily deformed or damaged, and has excellent low temperature and corrosion resistance. Long term contact with liquid nitrogen will not rust, effectively extending equipment service life and reducing equipment replacement costs;

2. Supporting configuration parameters: Equipped with 10 dedicated square buckets, each bucket is designed with multiple layers of storage space, which can be adapted to various types of freezing boxes, facilitating sample classification storage, archiving, and quick search, avoiding sample confusion, further improving sample management efficiency, and adapting to batch sample storage and high-frequency retrieval needs;

3. Temperature parameters: The tank can maintain a stable low-temperature environment of -196 ℃, unaffected by external temperature changes, and can retain the activity of biological samples. It is suitable for long-term storage of various biological samples such as cells, microorganisms, frozen sperm, vaccines, pathological sections, etc;

4. External dimension parameters: The total height is about 920mm, the outer diameter is about 750mm, and it occupies a compact area without taking up too much space. It can be flexibly placed in various scenarios such as laboratory workstations, small sample storage corners, and livestock breeding base storage rooms, adapting to environments with limited space;

5. Adaptation standards: Compliant with the industry standard GB/T 16774-2021, with standardized production processes and reliable quality, it can be widely used in various fields such as scientific research experiments, clinical testing, animal husbandry breeding, and small-scale sample banks.

All the above parameters are in line with the core performance characteristics of the YDS-175-216 large-diameter square bucket liquid nitrogen tank, and the data is authentic and referenceable. It clearly presents the advantages of the equipment's "large-diameter, low consumption, safe and durable, lightweight and practical", and also specifies the key data required for daily use and selection. It balances professionalism and universality, helping users quickly and comprehensively understand the product, providing reliable references for product selection, daily operation and maintenance, and adapting to the needs of small sample libraries and the early stages of library construction.
