FAQ

About liquid nitrogen

How quickly does liquid nitrogen evaporate from the Dewar vessel?

It depends on the type of vessel and its volume, usually the evaporation characteristics are indicated in the passport or the operating instructions of the Dewar vessels` manufacturer. Evaporation discharge (liquid nitrogen) is measured in kg/hour or in vol.% per day. The average storage time of liquid nitrogen before its full evaporation can be from several weeks to a year.

What is the difference between Dewar vessels produced in Ukraine and France?

First of all, it is volatility. For example, the vessel SDS35Bio60 produced in Ukraine holds nitrogen during 210 days, and its French analog B2036 - 360 days. Also more attractive appearance of the French manufactured Dewar vessels is one more important difference.

Is it necessary to close the Dewar vessel so that nitrogen does not evaporate?

To close the neck of the vessel tightly with any foreign plugs is not allowed. Use only original plugs and covers, which among other things prevent liquid nitrogen splashing. And also it prevents formation of "snow coat", ice in the neck and on the outer surface of the Dewar vessel. If mechanical damages and/or "snow coat" appear on the outer surface of the vessel (especially when it is completely frozen!), it is necessary to empty the vessel from liquid nitrogen, leave to warm and contact us for consultations.

Why is not allowed to drop a swap bud into a Dewar vessel?

Foreign objects in a vessel with liquid nitrogen can create an ice cork and result to the vessel destruction.

Can I smoke in the car when transporting a Dewar vessel with liquid nitrogen?

No

Do you need any documents for transportation of liquid nitrogen in the car?

In accordance with the Rules of the "European Agreement concerning the International Carriage of Dangerous Goods by Road (ADR)", liquid nitrogen in quantities up to 333 kg can be transported without observing restrictions specified for dangerous goods. This rule is confirmed by Order №73 of the Ministry of Transport of the Russian Federation dated 08/08/1995.

It is allowed to be transported in one transport unit without observing the above Rules for Dewar vessels SC-16 filled with liquid nitrogen in amount up to 15 pcs.

Can I order the delivery of nitrogen for tomorrow? For a certain day?

Delivery of nitrogen is carried out within two working days, in summer - within three working days. We cannot say in advance when exactly the order will be delivered, it depends on the route of the drivers.

Is the liquid transfer device connected to the power network?

No.

What is the operation principle of the liquid transfer device? Is there a pump?

Principle of operation of the liquid transfer device is based on pressure increasing in the cryogenic vessel by introducing "warm" mass into the liquid and using gas-lift effect. After sealing the neck of the vessel evaporated part of the liquid creates overpressure in it, followed by liquid transfer to siphon and further into the filled container.

No additional devices for liquid transfer are required.

Why does the liquid transfer device not to fit all Dewar vessels?

A part of the liquid transfer device inserted into the Dewar vessel is a rigid structure and is adapted only to a vessel of certain height.

A liquid transfer device for Dewar vessels with necks of different diameters is possible to be used with an additional seal.

Which Dewar vessel is better to order for CryoInej refilling and why?

Dewar vessels SK-16 or SK-25 depending on the patient stream. The cryosurgical unit CryoInej is to be periodically refilled, so it is necessary to choose the vessels to which there is a liquid transfer device. To pour liquid through the funnel is uncomfortable and difficult.
