The transfer caps have two ports: One port ends in a 0.2 µm filter, and the other port is chemically resistant, heat sealable flexible tubing, ending in either a Male Luer Lock or a Male Polycarbonate quick connect. The dip tube reaches all the way to the bottom of the flask for easy aseptic transfer of your liquid handling processes.
