Similar to CG-1924, but with a choice of our NEW CG-911-A 0-14mm sidearm valve, a straight through 0-12mm CG-510 valve or 0-20mm CG-511 sidearm valve. All valves are designed to seal flush with the bottom of the flask avoiding the dead space normally associated with stopcock drains. This feature permits total mixing and draining of the contents of the reactor. The CG-510 is recommended for solution based reactions while the CG-911-A and CG-511 are recommended for reactions containing any solids. Reaction vessel is constructed with a flange having a groove formed in the sealing surface of the flange. Flange is also ground to permit a greased seal with any of the lids CG-1940 through CG-1946. Supplied complete with two polypropylene hose connections and two screw caps (Polypropylene hose connections with a Viton rubber seal for working temperatures up to max +110° C.) For clamp see CG-141 or CG-141-T. For o-ring see CG-147.
