Abstract
System for mixing four components including a first syringe arrangement and a second syringe arrangement each with two chambers for holding components. Each of the two respective chambers of the syringe arrangements are connected in a uniquely defined fashion due to specific means for connecting the syringe arrangements. A component held by one chamber is mixed with a component of the corresponding other chamber by transfer into the other chamber. After mixing and disconnecting the second syringe arrangement from the first syringe arrangement, the two component mixtures in the chambers of the first syringe arrangement are further mixed and discharged by means of a mixing device which is to be connected to the first syringe arrangement. The connecting means allows connecting of the mixing device to the first syringe arrangement only after removal of the second syringe arrangement and a portion of the connecting means.
