Abstract
A vessel storing a batch of chemicals for delivery into a dialysate preparation tank includes a machine readable indicator, permitting automatic identification of the contents of the vessel prior to operating the vessel and introduction of chemicals into a tank where the dialysate solution is mixed. Various types of machine-readable indicators may be used, such as, for example, 'touch' memory buttons, bar codes, or magnetic strips. Suitable reading devices for the machine-readable indicators are provided for reading the contents of the bottle.
