Abstract
A machine adapted to fill liquid products, under sterile conditions, into bottles has at least one quantitation pump and a piston servo motor for driving the same. The stroke of the servo motor can be adjusted to suit the quantity to be supplied to each bottle, and a sterile filter is fitted downstream of the pump. A valve is provided to disconnect the pump from the source supplying the liquid, and permit testing of the filter by means of pressurized air or gas. This may be supplied by the pump or by an external source.
