Pope Scientific Lab Grade Dewars

Pope Scientific Low Form Dewars

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.

STANDARD WIDE MOUTH CYLINDRICAL DEWARS

• These Dewars exemplify the emphasis placed on both efficiency and safety by Pope Scientific.
• All Pope 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.

FULL LENGTH ALUMINUM HOUSING CYLINDRICAL DEWARS

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.

NARROW MOUTH DEWARS

Lab Grade Dewars with a narrow mouth are ideal for temporary storage or for room-to-room transfer (Not for DOT/Vehicle transfer). Standard features include low evaporation cork stopper, fully shielded evacuation tip, weighted bases and partial aluminum base.
