Condition & Details:
Up for sale is a rare, custom-built deep-draw glass vacuum Dewar flask manufactured by Pope Scientific. This unit was originally paired with a vintage 1970s laboratory cryostat system and was engineered specifically for long-component immersion, sensor testing, or deep cold-finger applications.

The inner silvering is fully intact, bright, and highly reflective with no signs of fogging or vacuum degradation. The inner glass chamber is clean and completely free of cracks or chips. Because purchasing custom-blown, high-vacuum scientific glassware of this scale brand new costs thousands of dollars, this is an excellent opportunity for an active research lab or industrial facility to acquire a premium deep-immersion unit at a fraction of the cost.

Shipping Note: This item will be packed with professional-grade materials, heavily double-wrapped, and securely suspended to guarantee safe transit.
