These jacketed, cylindrical borosilicate glass reaction vessels are without constriction at the top and have a flat bottom. They feature sturdy walls and a tooled flat flange with a surface ground to assure a tight seal. There is a gently sloping contour at junction of side wall and bottom, thus preventing any weakening that might occur with a sharp shoulder. Jacket has 1/2" hose connectors.
NOTE: Uses LG-7316 clamps.
