Fluidic systems, fluid containers and processes for washing fluid lines

摘要

The present invention pertains a process for automatically washing fluid lines of a fluidic system for combining liquid samples with one or more reagents, said system being provided with at least one main line connected to one or more reagent lines for feeding reagents, each of which being connectable to a reagent container by a fluidic connector, at least one sample intake for intaking samples and at least one pressure actuator for generating a positive or negative pressure in said fluid lines. The comprises one or more procedures selected from: procedure I: drawing wash fluid from a wash fluid reservoir connected to said main line into said main line and discharging wash fluid into a waste compartment for receiving waste fluid of a cleaning container connected to at least one reagent line (8) by said fluidic connector; procedure II: drawing wash fluid from at least one fluid compartment containing wash fluid of at least one cleaning container connected to at least one reagent line by said fluidic connector into said main line and discharging wash fluid from said main line into at least one waste compartment for receiving waste fluid of said cleaning container; procedure III: drawing wash fluid from at least one fluid compartment containing wash fluid of a cleaning container connected to at least one first reagent line into said main line and discharging wash fluid from said main line into at least one waste compartment for receiving waste fluid of a cleaning container connected to at least one second reagent line being different from said at least one first reagent line.
