Ace Glass Mineral Oil Bubbler 220 mm

The Ace Glass 8761-10 is a 220 mm mineral oil bubbler designed to serve as a high-integrity one-way vent for laboratory systems. It is a fundamental component for maintaining inert atmospheres in reaction setups, such as Schlenk lines or manifold systems, by preventing atmospheric oxygen and moisture from entering while allowing excess gas to escape safely.

Core Design Features

• Suck-Back Protection: The standout feature is the integrated reservoir head. If the system experiences a sudden drop in pressure (vacuum), the mineral oil is pulled into this reservoir instead of being sucked back into your reaction vessel, preventing contamination.

• Flow Monitoring: The lower chamber allows for clear visual confirmation of gas flow. By observing the rate of bubbling, you can qualitatively adjust your inert gas pressure.

Used; excellent condition.
