摘要：
An apparatus and method that allow multiple samples of a liquid in a primary container (here called a ‘pouch’) to be taken with minimal danger of contaminating the liquid in the container during the sampling process are disclosed. In an embodiment, a closed sterile sight chamber is connected with the pouch in a sterile manner to allow fluid to flow into the chamber while at the same time allowing air within the chamber to be displaced through a bacterial filter to atmosphere. The connection between the sight chamber and the pouch is then terminated (severed or closed), isolating the pouch from the sampling apparatus. Only then are samples of liquid withdrawn from the sight chamber, while allowing air to flow into the chamber through the bacterial filter.
