ABSTRACT:
A pressure equalizing liquid addition funnel for a closed system reactor is described. The funnel includes an internal valve stem which seats in the outlet port and extends therethrough and which defines a lumen which extends axially from below the outlet port upwardly to a port in the valve stem in the upper portion of said flask. The valve stem then terminates in a valve cap which is threadedly mounted on the funnel whereby rotation of the cap will cause the valve to engage or disengage a valve seat at the outlet.
