Abstract
A dilution apparatus (100) for diluting a fluidic sample in accordance with a specifiable dilution ratio, wherein the dilution apparatus (100) comprises a dilution fluid supply device (102) configured for supplying a dilution fluid at a first quantity per time, a transport fluid supply device (104) configured for supplying a transport fluid at a second quantity per time, a first fluid accommodation unit (106) configured for accommodating a first fluid volume, a second fluid accommodation unit (108) configured for accommodating a second fluid volume, and a control device (110, 112) configured for controlling the flow of the dilution fluid, the transport fluid and the fluidic sample so that in a first operation mode, the fluidic sample, being accommodated in the first fluid accommodation unit (106), is forced to flow to the second fluid accommodation unit (108) while being diluted by being mixed with dilution fluid, and in a second operation mode, the mixture of dilution fluid and fluidic sample, being accommodated in the second fluid accommodation unit (108), is forced to flow from the second fluid accommodation unit (108) to the first fluid accommodation unit (106) while being furt…
