cOFM probes are normally used at the same flow rate for P1 and P2 (e.g. 0.3 to 1 µl/min), but as the pump is also designed to operate dermal probes, flow rates might vary depending on the experiment. Joanneum Research recommends operating dermal probes (a/d OFM-P-15) with a slightly higher PUSH- than PULL-flow rate e.g.  1.1/1.0 µl/min.
