The dialyzer or the preparation unit in accordance with claim 8 , wherein the dialyzer or the preparation unit includes an element configured such that the acid liquid concentrate located in the container coupled with the dialyzer or with the preparation unit can be led off or is led off through the element from the container, the element being the introduction element of the container.

11. The dialyzer or the preparation unit in accordance with claim 8 , further comprising a control or regulation unit configured to control or regulate at least one or a supply of the liquid and the gas into the container, a leading off of the gas from the container, and a leading off of the acid liquid concentrate from the container.

12. A dialyzer or a preparation unit, the preparation unit serving the manufacturing of a concentrate for manufacturing a dialysis solution, the dialyzer or the preparation unit comprising:

a connection element via which (i) a compressed gas line is connectable to or connected to a liquid line, with a liquid and a gas being suppliable via the connection to a container that includes therein a dry concentrate, and (ii) an acid liquid concentrate is led off from the container.

13. The dialyzer or the preparation unit in accordance with claim 12 , further comprising a control or regulation unit configured to control or regulate at least one of a supply of the liquid and the gas into the container, a removal of the gas from the container, and a removal of the acid liquid concentrate the container.

14. A method of manufacturing an acid liquid concentrate which serves the manufacture of a dialysis solution, said method comprising the following steps:

coupling the container in accordance with claim 1 to a dialyzer or to a preparation unit;

introducing the liquid and the gas into the container to dissolve the dry concentrate therein; and

leading off from the container of the acid liquid concentrate obtained by the dissolving of the dry concentrate therein.

15. The method in accordance with claim 14 , further comprising a step of removing the gas from the container.

16. The method in accordance with claim 14 , wherein the acid liquid concentrate located in the container is only led off from the container when the dry concentrate located therein is completely dissolved.

17. A method of manufacturing a container in accordance with claim 1 , said method comprising the following steps:
