More information:
These flasks are manufactured for use with liquid nitrogen (LN
2
) and ideal for use with liquid gases. A strong, lightweight aluminum shield encases the flask from cover to base and also serves as a stand. Accidental breakage from dropping or other impact is reduced.
The glass container is attached firmly to the interior of the aluminum case. Flasks are completely silvered and evacuated, ready for use.
Pope Lab Grade Dewars are rated the most efficient glass Dewars in the World! This superior ranking is due to rigid quality controls in manufacture and a number of outstanding design and manufacturing features.
Efficiency assured by rigid bakeout and evacuation control (evacuated to 10-5 torr or better).
Evacuation tip completely shielded for increased protection
Weighted bases on all models for stability
Optional full length metal housing on most models for added protection
No pads between walls on cylindrical Dewars eliminating this heat transfer potential
Supplied stopper tops off Dewars to minimize evaporation
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. The hemispherical line has been expanded to provide additional Dewars to fit larger flask sizes.

Inside Diameter: 91mm
