<p>A system for delivering sterile dosing liquid to fluid flowing through a supply pipe (18, 20) from a source of fluid (10) to a packaging machine (22) utilizes a peristaltic pump (34) connected to a flexible supply line (33) from the source of sterile dosing liquid (30) to a hollow needle (36). The supply pipe comprises at least two sections (18, 20), interconnected together with a resilient rubber-like gasket (19); and said hollow needle (36) is inserted through said gasket (19) to supply sterile dosing liquid to the fluid flowing through the supply pipe.</p> |
