Abstract

A dosing apparatus for continuous injection of a small amount of secondary sterile liquid into a free-flowing primary sterile liquid. The dosing apparatus has a controllable valve with a movable closing sleeve (16) for controlling the supply of secondary sterile liquid to the flowing sterile primary liquid and an outer valve member (18), which in itself comprises an inner part (17) which is displaceable in relation to the valve member (18) and which has a recess or duct (19), whose end facing the closing sleeve (16) is covered with a sealing protective wafer (8). A supply tube (12) for supplying secondary sterile liquid is arranged in said recess or duct (19). Finally, the dosing apparatus has a means (24) for rupturing the protective wafer to allow said injection of the secondary sterile liquid into the primary sterile liquid through the supply tube (12). The invention also concerns a method of using said dosing apparatus.
