1. A functionally closed system for maintaining sterile conditions while collecting and sampling biological fluids comprising:

  • a tubular line for withdrawing biological fluids during a collection procedure;

    a sample receptacle connected to said tubular line, said receptacle comprising a sample reservoir and an entry tube connected to said reservoir and to said tubular line for enabling said fluid to flow into said reservoir;

    a radio frequency heating apparatus with jaws sized to surround and heat said entry tube to close said tube; and

    a thermal insulating sleeve means located around said entry tube, said sleeve means having a low dielectric loss coefficient for insulating said entry tube from said jaws when said jaws are used to close said entry tube after filling said reservoir;

    whereby when said sample reservoir is filled with fluid and removed from the closed system to enable laboratory analysis of said fluid the sterility of said closed system is not compromised and danger of spillage from said entry tube or said sample reservoir is averted.
