This gas balloon type adapter, made of borosilicate glass, is used for protective storage in jointed vessels.

• The inert gas tubing may be disconnected, giving the vessel its own portable inert gas source to balance volume changes caused by sample removal
• Supplied without the balloon
• Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements

One arm of the T-bore stopcock is connected to the inert gas source. The arm with a hose connector is connected to a balloon. Vessels connected to this adapter may be flushed and filled with inert gas. The balloon can be expanded with inert gas for storage at the same time or separately. The stopcock bore is then rotated to connect the balloon to the vessel.

Conforms to USP Type I, ASTM E438 and Type I class A requirements.
