The invention provides a first concentrate comprising lactate and calcium ions, said first concentrate having increased stability against precipitation at temperatures around +4° C., said first concentrate being useful for preparing a ready-to-use dialysis fluid by mixing said first concentrate with water and optionally a second concentrate comprising glucose, wherein that the lactate concentration L(expressed in moles per litre, M) of the concentrate fulfills the conditions: a) L>0.8 M; and b) L<(1.9−0.4×Ca) M; and wherein Cais the calcium concentration of the ready-to-use dialysis fluid expressed in millimoles per litre (mM).

Dialysis concentrate

The present invention concerns a system for preparing a ready-to-use peritoneal dialysis fluid. The system comprises a) a proportioning device; b) at least one source of water; c) at least one source of first concentrate adapted for connection with a) and b), d) at least one source of second concentrate adapted for connection with a) and b), and optionally, e) at least one source of further concentrate adapted for connection with a) and b), wherein the first concentrate comprises glucose and has a pH of between 1.5 and 4, and wherein the second concentrate comprises a physiologically acceptable buffer and has a pH of between 5.5 and 9.0.
