Systems for inactivating fluid cultures through heating

A fluid holding system comprising:

• a tank assembly having an interior surface bounding a chamber, the tank assembly comprising a sidewall encircling the chamber and extending between a first end and an opposing second end, the first end bounding an opening to the chamber;
• and
• a collapsible bag removably disposed within the chamber of the tank assembly and being comprised of one or more sheets of polymeric film, the collapsible bag bounding a compartment adapted to hold a fluid;
• a port coupled with the bag and communicating with the compartment;
• and
• a support projecting from an interior surface of the sidewall so as to be completely disposed within the chamber of the tank assembly, the port being supported by the support so that the port is disposed within the chamber at a distance from the sidewall.

A fluid heating system comprising:

• a tank assembly having an interior surface bounding a chamber, the tank assembly comprising:
• a sidewall encircling the chamber and extending between a first end and an opposing second end, the first end bounding an opening to the chamber;
• and
• a lid movable between a first position wherein the opening to the chamber is exposed and a second position wherein the lid is disposed over the opening;
• a collapsible bag removably disposed within the chamber of the tank assembly, the collapsible bag bounding a closed compartment adapted to hold a fluid, the compartment being closed when the lid is in the first position and the second position;
• means for controlling the temperature of fluid within the collapsible bag when the collapsible bag is positioned within the chamber of the tank assembly, the means for controlling the temperature of the fluid comprising:
• a fluid channel disposed within the lid of the tank assembly;
• and
• a fluid line fluid coupled to the fluid channel for delivering a secondary fluid into the fluid channel
• a boiler for heating the secondary fluid;
• and
• a pump for pumping the heated secondary fluid from the boiler, through the fluid line, and to the fluid channel disposed within the lid of the tank assembly.
