1. A gravity-fed burette system, comprising:
a hollow body providing a generally upright longitudinal axis which encloses a chamber to receive a liquid, wherein the chamber has a chamber outlet for delivering liquid from the chamber, a vent port from the chamber, a Primary IV bag inlet into the chamber, and a directed flow inlet into the chamber from a chamber valve;
a Primary IV bag inlet control valve operatively associated with the Primary IV bag inlet to restrict flow from the Primary IV bag inlet into the chamber;
a Primary IV bag branch into the chamber valve;
a Primary IV bag branch control valve operatively associated with the Primary IV bag branch to allow liquid to flow from the Primary IV bag branch through the chamber valve into the chamber;
a Secondary IV bag inlet into the chamber valve;
a Secondary IV bag inlet control valve operatively associated with the Secondary IV bag inlet to allow liquid to flow from the Secondary IV bag inlet through the chamber valve into the chamber; and
a drug port inlet into the chamber valve;
wherein the chamber valve allows liquid to flow through the drug port inlet into the chamber in a first configuration and allows liquid to flow from the drug port inlet through the chamber valve into the Secondary IV bag inlet in a second configuration.
