A fluidics module has first fluidics structures having a first fluid chamber, second fluidics structures having a second fluid chamber, a first connection having a fluidic resistance between the first fluid chamber and the second fluid chamber, third fluidics structures having a third fluid chamber, a second connection having a barrier between the first fluid chamber and the third fluid chamber, a pressure compensation channel between the second fluid chamber and the third fluid chamber, and fourth fluidics structures having a fourth fluid chamber connected to the second fluidics structures via a third connection. Liquid can be transferred centrifugally from the first fluid chamber into the second fluid chamber. Liquid from the second fluid chamber can be transferred under rotation into the fourth fluid chamber via the third connection to generate negative pressure in the third fluid chamber. The barrier can be overcome by liquid from the first fluid chamber due to the negative pressure generated to transfer liquid from the first fluid chamber into the third fluid chamber via the second connection.
