Metal Magdeburg Hemispheres — Heavy‑Duty Cast Iron (each)

The United Scientific Metal Magdeburg Hemispheres provide a durable, high‑performance demonstration tool for teaching atmospheric pressure and vacuum principles. Constructed with thick cast iron walls and fitted with large steel handles, these hemispheres closely replicate the robustness of the original 17th‑century design. Their heavy‑duty build ensures long service life in classroom and laboratory environments.

A plated brass valve and precision machining help prevent leakage, allowing the hemispheres to form an airtight seal when evacuated. This makes them ideal for physics demonstrations involving vacuum pumps, force, and pressure differentials. The hemispheres measure 4.25 inches in diameter including sealing flanges, with a 4‑inch internal sphere diameter.
