nalgene polyethylene dewar flaskarrow12Nalgene® Polyethylene Dewar Flask

High density polyethylene Dewar Flask with vented and insulated HDPE covers. They are unbreakable, chemically resistant, and withstand temperatures from -196 to 100°C (-321 to 212°F). Double walls are filled with foamed urethane to minimize heat exchange. May be used for short term storage of dry ice-solvent, liquid nitrogen, or for use as a hot bath. They are ideal for storing frozen biological specimens. All available sizes feature molded-in-ribs for stability and a carrying handle on the 1, 2, and 4 liter sizes.

arrow12Foam Cryo Dewars

The preferred containers for handling liquid nitrogen and cryogenic materials

These foam dewars are safe, durable, and have superior insulating properties compared to stainless or glass, at a fraction of the cost!

Foam dewars use fine closed cell foam for insulation, which is chemically inert and mechanically durable enough to be exposed directly to liquid nitrogen, without leaking or degrading.

Also, due to the lower thermal mass, foam vessels cause less liquid nitrogen boiloff when filled, and will accumulate less frost. This results in less liquid nitrogen being used.

All vessels feature a foam lid.

arrow12Low Form Shallow Dewars

Low Form Shallow Dewars permit essential operations that are not practical with standard cylindrical or spherical Dewars.

These operations include:

  • Insertion of small flasks in Dewar
  • Agitation in flask with magnetic stirrer
  • Rapid freezing and recovery of tissue/organ specimens
  • Tempering of stirring rods, pestles and other small objects

The protective aluminum bases on both the hemispherical and cylindrical dewar styles extend the full height of the Dewars.

Note that protected vacuum tip-off tubulations are offset to the side to minimize space between the Dewar bottoms and magnetic stirrers.

The hemispherical line has been expanded to provide additional Dewars to fit larger flask sizes.

Lab Grade Dewarsarrow12Lab Grade Dewars

These lab grade dewars are rated the most efficient glass Dewars in the World! The superior ranking is due to the rigid quality control when manufacturing, along with superior design and manufacturing features.

  • Weighted bases on all models for stability
  • Supplied stopper tops off Dewars to minimize evaporation
  • Evacuation tip completely shielded for increased protection
  • Optional full length metal housing on most models for added protection
  • No pads between walls on cylindrical Dewars eliminating this heat transfer potential
  • Efficiency assured by rigid bakeout and evacuation control (evacuated to 10-5 torr or better)

The protective aluminum bases on both styles extend the full height of the Dewars.

Note that protected vacuum tip-off tubulations are offset to the side to minimize space between the Dewar bottoms and magnetic stirrers.

All Wide Mouth models can be obtained with an exterior metal housing that extends nearly to the top rim of the Dewar (a slight extension of the glass Dewar facilitates pouring). This housing adds the safety of metal to the efficiency of glass, particularly important in handling operations.

Lab Grade Dewars with a narrow mouth are ideal for temporary storage or for room-to-room transfer. Standard features include low evaporation cork stopper, fully shielded evacuation tip, weighted bases and partial aluminum base.

All Lab Grade Dewars are manufactured of borosilicate glass for liquid nitrogen service. A sturdy mesh cover facilitates a firm grip, provides a cushion against bumping and increases protection.
