Cerko micropump/ membrane microdosing unit is a system controlled by microprocessor, intended for routine liquid dosing during measurements, titrations, preparing standard solutions or programmed content mixtures.
Varying on version, the dosing unit consists of one or two dosing channels. It is possible to develop the dosing system through combination of many dosing units.
Dosing set is controlled by CerkoLab program and it allows constant as well as step-by-step liquid dosing. Following parameters can be programmed: size of a single dose, dosing speed, number of portions and pauses between particular doses.
