(2) All glass manifold for connecting inert gas and vacuum sources to sidearm stopcocks. Each stopcock has a glass threaded end to provide a vacuum connection. Upper left and lower right ends open.
(3) All glass manifold for connecting inert gas and vacuum sources to sidearm stopcocks. Stopcocks are 4 mm bore with lower vacuum chamber. Lower right and Upper left ends open.
(4) With 0-4 mm high vacuum, easy action Teflon, three-way stopcocks for takeoffs. Beams are 1/2" O.D. with upper-left and lower-right ends open. Distance between values is 100 mm.
With three 0-5 mm high vacuum Teflon stopcocks with #11 internal threads and nylon bushings. Stopcocks are positioned parallel to main body to allow operation from front or back. One end can be connected to a vacuum trap and the upper internal thread/bushing can be connected to a thermocouple vacuum gauge.
