Bubblers

Lab glassware bubblers are components that prevent a liquid (usually mineral or silicone oil) from "backflowing" into the prior components in the glass system. Bubblers typically have hose connections as their intake opening, often with a built-in stopcock so that the inflow can be halted as desired.

In chemistry glass applications, bubblers are used to prevent the cleanup or contamination that results from unwanted backflow.

Our lab bubblers include various styles for compatibility with a wide variety of glassware systems.
