Tubing clamp for medical applications

Systems, methods, and devices for preparation of purified water and medicaments for various uses including blood treatment are described. Methods, devices, and systems for creating multiple-treatmentbatches are described. For example, a medicament fluid circuitcan include a container with an interior chamber. The container can have a fluid filling port and a fluid extraction port. Both ports can be connected to the interior chamber. The filling port can have two sterilizing filters, each of which has a membrane. The sterilizing filters can be connected in series the membranes are separated by a distance of at least 0.5 cm. A first of the sterilizing filters can have a sealed inlet. The fluid extraction port can be sealed.
