Haier Biomedical Aluminum Alloy Liquid Nitrogen Biological Container

Haier Biomedical Stainless Steel Liquid Nitrogen Container

At present, Haier Biomedical Liquid Nitrogen Container products focus on the biomedical field, centering on the storage of biological samples, providing users with complete solutions for biobank sample management. The liquid nitrogen products mainly include three categories: stainless steel liquid nitrogen container YDD series, aluminum alloy liquid nitrogen container YDS series and self-pressurized supply container YDZ series (made of aluminum alloy or stainless steel). Its applicable settings cover the whole range and requirements for biobank management, sample storage and sample transportation. 

Haier Biomedical has developed the technological accumulation and mature temperature control and vacuum insulation technology, which truly achieves high efficiency and low consumption; the container body is manufactured with an integrated design, which can achieve a super-high anti-vibration effect. At the same time, the application of advanced Internet of Things (IoT) technology and is fitted with the cloud monitoring management software platform ensures real-time data transmission and access, which will further ensure the safety of samples while giving users a more convenient and efficient user-friendly experience.

In addition and in order to further help users understand the product, the following questions are frequently asked by users, we have confirmed the accuracy with the technical team.

Q&A

Q:

What is the average liquid nitrogen consumption of YDD series stainless steel liquid nitrogen containers, and what type of liquid nitrogen supplement is used?

A:

Taking YDD-850-465 as an example, the average daily liquid nitrogen consumption is 7.8442 L. It adopts a manual and automatic integrated liquid nitrogen supplement form, users do not need to replace the connecting pipe interface when refilling liquid nitrogen, which is much more convenient and safer than the traditional operation of pouring liquid nitrogen from the opening head of the container.

Liquid Feed System

Q:

How to monitor the status inside the YDD series stainless steel liquid nitrogen container to ensure sample safety?

A:

In terms of temperature and liquid level measurement, Haier Biomedical offers two measurement methods for users to choose: differential pressure and capacitance; temperature and liquid level are measured and controlled separately, with interlocking function to achieve multiple security guarantees; at the same time, multiple alarm signals are in place to ensure sample safety; support external network, internal network, wired and wireless network communications to achieve remote monitoring.

Q:

Can the structure of the YDD series stainless steel liquid nitrogen container achieves gas-phase storage?

A:

Both gas and liquid phases can be used; the lowest temperature at the top of the freezer rack can reach -190°C when it comes to gas phase storage.

Q:

What are the characteristics of the auxiliary access extraction device for the freezer rack?

A:

Our freezing storage rack auxiliary access extraction device has the following five features that are easy for users to operate: adopting slide rail design, the user can freely slide the sling to the lifting position; the lifting system is manouverd by remote control; equipped with weight limit protection function, the weight limit is 20kg; the sling hook has a laser positioning function; the rotation angle is 350°, easy to move in any direction.

Q:

What is the working principle of YDZ series self-pressurized supply container?

A:

When the inner container is filled with liquid nitrogen, the vent valve, the discharge valve and the pressure reduction valve is closed, and the liquid nitrogen injection port is screwed tightly. In the case of no leakage, due to the heat transfer of the container shell to the pressure increasing tube, part of the liquid nitrogen that enters the tube by itself is absorbed due to the heat transfer and is vaporized.

When the pressure increases valve is turned opened, the vaporized nitrogen passes through the valve and immediately enters the upper space above the inner container liquid surface. At the same time, the liquid nitrogen in the container inner container continuously enters the pressure increase tube to absorb the heat and is vaporized. Due to the volume of vaporized nitrogen being more than 600 times that of liquid nitrogen, a large amount of gas phase nitrogen obtained through a small amount of liquid nitrogen being vaporized continuously enters the inner container through the opened pressure increase valve. With the increase in the amount of entering nitrogen, the nitrogen accumulated in the upper space above the liquid surface of the inner container gradually generates pressure on the inner wall and the liquid surface. When the pressure gauge value reaches 0.02 MPa, open the discharge valve and the liquid nitrogen will be discharged through the drainage pipe.

Q:What are the features of YDZ series self-pressurized supply containers?

A:

Convenient to fill liquid nitrogen: just unscrew the plug of the liquid nitrogen injection port, you can use the liquid machine fractionation tower discharge outlet or pipeline to fill.

Fast pressurization and convenient operation: The pressurization method of applying pressure generated after a small amount of liquid nitrogen is vaporized to the inner container, which is convenient for operation, fast to raise pressure, and ensures the purity of liquid nitrogen.

Superior safety and reliability: The discharge pressure of the container is extremely low, and it is equipped with a pressure gauge, a safety valve, and a vacuum sealed joint. Therefore, the container is safe and highly reliable in use.

High strength materials: The outer shell, inner container and main parts are all made of austenitic stainless steel with good vacuum and low temperature performance.

Q:

What settings are the YDS series aluminum alloy liquid nitrogen containers suitable for?

A:

It can be used in biobank, laboratory sample storage, sample transportation and other settings. The product volume covers 2-175L which can meet different storage capacity requirements and space conditions. Also, the transportation series can meet the transportation needs and can be equipped with smart cap. The temperature data during transportation is clear at a glance; it adopts gas phase storage, no fear of liquid nitrogen overflow; stainless steel mesh screen divides the storage which makes it easier to store different samples.

Q:

What technologies are used in YDS series aluminum alloy liquid nitrogen containers?

A:

The inner container insulation material is handled by automatic winding equipment; adopting the intermittent evacuation process, the evacuation period is longer than 120 hours; the product surface is sprayed with plastics; all products are tested at 100% liquid nitrogen, and the liquid nitrogen loss of each product is accurately recorded to verify the reliability of each product under low temperature conditions.

Aiming to create the best user experience, Haier Biomedical will continue to invest in product technology and design upgrades, quality control flow, optimized detailed design and provide the best product solutions for users with different needs!
