Foam 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.

61886 Series, Hemispherical Dewars
61887 Series, Cylindrical Dewars
Low 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 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.
