LN2 Storage Dewars

We also supply Semen counting cells and well slides for checking semen viability.




Our storage Dewars boast extraordinary insulation, and therefore holding times, before LN2 replenishing is required. Best holding times are achieved by minimising the contact areas at the neck and support of the inner flask against the outer housing. Dewars with large neck openings have shorter holding times, but afford better access.

Consequently storage vessels (YD2), with the exception of the small 2 and 5 litre Dewars, are most used for the storage of semen or other specimen. These long storage time Dewars are not well suited for transport and they should not be tipped when full. Holding time is reduced with increased storage loads and the number of rods used to hold immersed specimens.

Remember that storage containers (except 2 and 5 litres), when full, must not be transported on a truck or tipped to decant some contents.

Our Dewar vessels are all aluminium, except where stated otherwise, making them light. This material has low specific heat (wastes less N2 when filling), and the natural Al oxide layer is extremely chemically inert. The design prevents denting of the outer housing.

Note: Total LN2 evaporation is the number of days from filling the Dewar, without decanting any, until all liquid N2 has dissipated.

DEWARS WITH HANDLES

These dewars are ideal for temporary storage of liquid gas in laboratory settings. These wide mouth cylindrical flasks have a convenient handle. These dewars can afford the increased portability, pouring efficiency and added protection. They provide safe extended temperature retention for specimens stored in liquid nitrogen, and thus have a broad range of applications in industrial, educational, and clinical fields.


Features

  • Aluminium metal housing extends full length of Dewar for added protection.
  • The Dewar lip is extended to facilitate pouring.
  • Polyethylene stopper, specially vented, minimises evaporation.
  • Holding time 2-6 hours depending on volume.

CANISTERS AND LADLE FOR DEWAR VESSELS

Stainless steel canisters are for sample storage in or just above liquid N2. The canisters have a coarse mesh at the bottom and a long handle for suspending within a Dewar vessel. Stainless steel is a very poor heat conductor at liquid N2 temperatures. Additionally these handles have a section of fibre glass to further reduce heat conduction.
Canister diameter is limited by the Dewar's neck size, and therefore larger canisters are not suited to smaller necks than designated.
Canisters have a holey bottom whereas a ladle has a solid bottom.
