Claims32
A bioprocessing vessel intended for receiving a fluid, comprising:
- a bag capable of receiving and holding the fluid, the bag having a flexible sidewall and a sparger welded to the bag to form a fluid-impervious seal, said sparger including a base being more rigid than the flexible sidewall of the bag, said base being carried by the bag, and a permeable film for forming gas bubbles in the fluid when present in the bag, said base being more rigid than the permeable film.
A bioprocessing vessel intended for receiving a fluid, comprising:
- a bag capable of receiving and holding the fluid, the bag having a flexible sidewall and an integral sparger having a base that is more rigid than the flexible sidewall of the bag welded to the flexible sidewall of the bag for forming gas bubbles in the fluid.
A bioprocessing vessel intended for receiving a fluid in need of sparging by way of a flow of gas, comprising:
- a bag capable of receiving and holding the fluid, the bag having a flexible sidewall;
- and
- an integral sparger for forming bubbles in the fluid from the flow of gas, said sparger having a base that is more rigid than the flexible sidewall of the bag, said sparger base comprising a peripheral flange having a face secured to the flexible sidewall of the bag and a rigid conduit projecting outwardly from the base for receiving the flow of gas.
A bioprocessing vessel intended for receiving a fluid, comprising:
- a bag capable of receiving and holding the fluid, the bag having a flexible sidewall and an integral sparger for forming gas bubbles in the fluid, said sparger having a base that is more rigid than the flexible sidewall of the bag welded to the flexible sidewall of the bag, said sparger further comprising a tube including a passageway adapted for receiving a gas.
A bioprocessing vessel intended for receiving a fluid, comprising:
- a bag capable of receiving and holding the fluid, the bag having a flexible sidewall and an integral sparger welded to the flexible sidewall of the bag, said sparger having a first portion that is more rigid than the flexible sidewall of the bag and a second, flexible portion for forming gas bubbles in the fluid.
