Line has 5-ports (A) with 4mm solid double oblique high vacuum stopcocks, CG-468-02, having a constant pressure retaining device, and 24/40 inner joints with hooks just above the grind. Ports are spaced 150mm center to center and have rod bracing to vacuum bank. Large ID of vacuum bank (40mm) provides for a substantial reservoir to quickly evacuate vessels up to 1000ml. End of the vacuum bank (B) has a 35/25 ball joint and is supplied with a 35/25 socket joint cap style stopper to help prevent induction of grease into line. A valved gauging port (C) is placed on the main vacuum line and has a 12/5 ball joint.
The inert gas line has 2-ports (D) for connection of the inert gas source and a bubbler. A valved, cross over line (E) is provided for evacuation of the entire system. End of the inert gas line (F) has a 14/20 inner joint and is supplied with a 14/20 outer joint cap style stopper.
Pre-trap (G) is 51mm OD x 250mm long with two 28/15 socket joints which connect the manifold and main trap assembly which have 28/15 ball joints. Main trap body (H) is 58 mm OD x 235mm long with a reversed 75/50 ball and socket joint connection. A valved gauging port (I) is placed between the main and pre-trap and has a 12/5 ball joint. Connection to the diffusion pump (AF-0450) or mechanical pump is made via a 1" OD tube (J) on the main trap assembly. Both traps can be isolated from the line for cleaning by the 0-12mm Chem-Vac™ Chem-Cap® valves (K). Spacing between the two traps is 175mm for easy placement of dewar flasks.
Complete system consists of one 5-port vacuum/inert manifold, one pre-trap, one main trap assembly, one main trap body, two CG-150-05 #28 S.S. pinch clamps, one CG-150-06 #35 S.S. pinch clamp, one CG-150-21 #75 S.S. pinch clamp, two CG-110-01 1/2" S.S. springs, one 14/20 outer stopper with hooks, and one CG-3014-05 35/25 socket stopper. System is available in right or left handed configurations. Overall dimensions are 40" W x 24" H.
