Abstract: An apparatus for the sterile filling of containers sterilizes the containers before supplying them, with their caps on, to a substantially airtight chamber for filling. A precision lead screw precisely positions each container under the appropriate capping/uncapping mechanism and the appropriate filling needle.

The minimized number of components of the system minimizes the potential openings through which unfiltered air may enter the apparatus. Keeping the containers capped except while they're actually being filled minimizes the opportunity for any bacteria or viruses to enter the container.
