The present invention relates to a sterile sample collection device for fluids and a method of using the same. It is comprised of a transfer device having a body with a bore formed through at least a portion of its interior. Contained within the bore is a movable plunger. The body has a first and a second end. The first end contains a face designed to be attached to the upstream component. The second end is connected to tube which is then connected to a collection bag. The plunger has corresponding first and second ends. The first end of the plunger when in the closed position is in alignment with the face of the body which combined form a steamable surface and a sterile barrier against the environment to the rest of the interior of the body, the plunger and downstream components.
