Concept - - Touchless Blast off 

The same DRD principle that gives the extraordinarily
wide volume range can also cleanly deliver tiny sample volumes!

Touchless Blast off! 

A small syringe pump trying to expel a tiny sample will give a "hanging drop" unless manually touched off. The DRD pump, however, can change internally to its single-piston mode to cleanly "blast off" the sample.
