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
