CRYOFARM LIQUID NITROGEN CONTAINERS

Dewar Cryofarm aluminum containers are designed to ensure the maximum duration when nitrogen is liquid, thanks to a special thermal insulation that drastically reduces the evaporation. In addition, the inner neck that connects the mouth of the container to the inner container is made of fiberglass to isolate the main sources of dispersion. The fiberglass links of the canisters are made of excellent quality too, lending them the right level of elasticity, strength and insulation.

In addition, containers are equipped with a valve that, thanks to the double seal, ensures the endurance of the gap vacuum-sealed.

The Dewar Cryofarm also have two special features:

  • small pedestal at the base that lifts them from the ground allowing greater thermal insulation, cushioning shocks and helping to avoid corrosion of the bottom;
  • a plastic lid designed to be closed with a padlock.

On our catalogue there are also available other types of liquid nitrogen containers:

  • YDH SERIES
  • CRYOGENIC FLASKS
  • PRESSURE CONTAINERS

CRYOFARM LIQUID NITROGEN CONTAINERS- YDS SERIES

Cryofarm YDS container are designed to store liquid nitrogen in it (-195.8°C). Built with top quality materials, particularly suitable for several needs, such as nitrogen storage and biological samples, mechanical and food industry and dermatology.

 

The constituent parts of the YDS container are:

 

  • cover (only available in containers with canisters)
  • lid
  • handle (differs depending on the model)
  • inner container
  • outer container
  • vacuum-sealed space between the two containers, filled with insulation materials
  • fiberglass neck
  • canisters

The YDS container is chosen in relation to its litres, capacity and to its diameter of the mouth. With the same capacity, a bigger diameter reduces the autonomy or “duration” of the container.  On the other hand, a larger opening permits to store more material inside the container as the storing canisters are much larger.

Containers with large mouth are particularly suitable for processing techniques, especially on metal pieces, directly inside of them (e.g. shrinking).

 

Cryofarm containers for biological samples stocking are provided with canisters or racks based on the client needs.

The cylindrical steel canisters are necessary in dewar for the preservation of biological material and for artificial insemination, where paillettes are used for semen storage. There are different canisters with different circumference (from 50 mm up to 120 mm) and height (120mm for the single level, 276 mm for the double level).

The racks, used to contain plastic boxes called cryobox, are necessary when biological samples are contained in vials or cryotubes. As for the canisters, racks dimensions vary depending on the inner dimensions of the container.

A YDS series is particularly indicated both for nitrogen and biological material transportation: it is the “B” series (i.e. YDS 20-50 B), which differs from the other series thanks to a connection between the outer and inner container. This expedient reinforces the structure and avoids oscillations, but on the other hand reduces its autonomy making the container less convenient for the mere use of storage.

CRYOFARM CONTAINERS - YDH SERIES

Cryofarm containers YDH series, also called “Dry shipper”, are designed for the cryogenic transportation of liquid nitrogen converted in dry vapor. The YDH containers are designed with premium quality materials and are particularly indicated for transportation, especially by air, of biological samples.

The main difference from the YDS series can be found in the inner container, which is filled with an absorbent material made to impregnate the liquid nitrogen and release it in the form of vapor.  Inside of this dewar there is only space for one central canister to prevent the release of liquid nitrogen even if the container is turned upside down.

 

The constituent parts of the YDH container are:

 

  • cover
  • lid
  • handle (changes depending on the model)
  • inner container
  • absorbent material
  • outer container
  • vacuum-sealed space between the two containers, filled with isolating material
  • fiberglass neck

As for the YDS, YDH is chosen depending on the liter capacity and depending on the diameter of the upper opening. The options are restricted in two models, YDH 3-50 with more autonomy but with less capacity of biological storage and YDH 8-80, with more biological storage capacity, but less autonomy.

FLASK

CRYOFARM CONTAINERS – FLASKS

Cryofarm flasks are little containers used to handle liquid nitrogen.

These flasks are made of steel, covered inside with a layer of borosilicate glass, useful for the insulation. They’re provided with a lid, but since the month is large, the evaporation is fairly rapid.

These containers are not suitable for the nitrogen storage due to its autonomy which lasts only few days.

 

Flasks can be used at temperatures higher than liquid nitrogen, for example to process and store dry ice, solid CO2 (-90,C) or liquid nitrogen vapors (-150,C approximately).

CRYOFARM CONTAINERS – PRESSURE

Cryofarm pressure containers are designed to optimize the storage and transport performance of liquid nitrogen and other cryogenic liquids. Made of stainless steel to increase reliability and durability, their insulation and their high pressure allow to limit the evaporation of the cryogenic liquid inside.

Pressure vessels are equipped with standard pressure setting device and level pressure indicator. Cryofarm also supplies them with diffusion nozzle and five-wheeled cart.
