  • Float device for density gradient fractionation
    Patent number: 4346608
    Abstract: A float device is provided for density gradient fractionation which permits continuous removal of liquid samples from the surface of the liquid within a tube. The float device floats on the liquid surface and is provided with a centrally disposed length of tubing which extends through the device to provide communication between the liquid surface and a suction source such as a peristaltic pump. A concavity in the bottom of the float assists in removing trapped air and minimizes turbulent flow, thereby assuring high resolution of obtained samples.
