U tube lab glass with side arms

Uses of U tube lab glass with side arms

• Gas Absorption:

U-tubes are commonly used in gas absorption experiments, where gases are absorbed in liquids. The side arm allows for the introduction of gas while the liquid is contained in the main body of the U-tube.

• Distillation:

In distillation setups, side-arm U-tubes can facilitate the collection of distillate or allow for reflux, enabling efficient separation of components based on boiling points.

• Reactions Requiring Gas Inlet:

They are used in reactions that require the continuous introduction of a gas, such as hydrogenation or the introduction of inert gases to maintain an anaerobic environment.

• Manometric Measurements:

U-tubes can serve as manometers to measure gas pressure differences in experiments, especially when side arms are utilized for connecting to other apparatus.

• Solvent Extraction:

In solvent extraction processes, U-tubes help to separate phases while allowing the introduction and removal of solvents via the side arms.

• Condensation:

The design allows for effective condensation of vapors, where one arm can serve as an inlet for vapor while the other collects the condensed liquid.

• Sample Collection:

The side arms facilitate the easy collection of samples without disturbing the main contents of the U-tube.
