You hit the nail on the head.

His pump is a 10-600 RPM motor, not a 6-600 RPM. That head flows at 2.8 ml per revolution with LS24 tubing. At 10 RPM minimum on his pump, that is 28 ml/min minimum with LS24 tubing on that pump.

LS-15 tubing is 1.5 ml per revolution which would get him down to a minimum of 15 ml/min. Seems a change of tubing is in order if the target flow is below 28 ml/min.
