Running the micropump below 1Hz

| 0

The pump can work even well below 1Hz (if necessary) but not every Bartels driver does support it. The mp-Labtronix controller has a frequency range of 1-300 Hz. The mp-Highdriver4 and the mp-Highdriver have a lower frequency limit of 50 … Weiter

Operating: mp-Labtronix

| 0

Driving the micropump with the mp-Labtronix allows you to gather comprehensive results in short time. You will also be able to consider the sometimes complex interaction of micro- and macrofluidics with direct measurements of your system right from the beginning. … Weiter

What is the SRS signal?

| 0

The SRS signal is an optimized waveform generated by the mp-Labtronix controller to drive the actuator more efficiently. It makes the pump work at a lower sound level with increased long-term stability of the flow rate. The SRS signal is … Weiter

Signal forms

| 0

The mp-Labtronix controller generates three different signal forms: SRS, Sine, Rectangular. The mp-Lowdriver generates only sine and a customized signal form. The mp-Highdriver and the mp-Highdriver4 generate different signal forms: sine, rectangular and other. The mp-Driver generates a SRS signal. … Weiter

Backflow behavior of the micropump

| 0

The micropump has an backflow when turning off, but this depends on the pressure in the system. The pumps are designed fluidically open, that means the passive valves inside the pump open on dynamic pressure changes. However, the valves are … Weiter
