This borosilicate manifold is intended to synthesize Diphosphine, a highly volatile compound that combusts when exposed to oxygen. It's critical to maintain anaerobic conditions during the synthesis. 

Working with the researcher's initial drawing, we came up with this design;  a 6-place vacuum manifold with a final trap that can be removed under anaerobic conditions. The idea is the synthesis will be run across each stage starting on the left-hand side of the manifold. As the synthesis progresses, each stage can be isolated under vacuum. At the final stage, the 6th place trap can be sealed with valves and removed under vacuum.

The construction features a high vacuum teflon bellows at this 6th place. The bellows allow for the flexibility to disengage the final product without breaking the vacuum, esentially providing an anaerobic transfer vessel.

The Teflon bellows connect in the same way as the trap bodies - with an NW16 glass flange and seal set.
