These manifolds are used to connect inert gas and vacuum sources to sidearm stopcocks (three-place, four-place or five-place manifolds). Which is manufactured from 33 expansion, low extractable borosilicate glass.

• Distance between valves is 100 mm
• Ports have 9 mm OD openings
• Sample contacts only PTFE and borosilicate glass

Each stopcock has a metering groove cut into the plug to provide fine control of vacuum sources and inert gases. Beams are ¹/₂" (12.7 mm) OD, with upper-left and lower-right ends open.
