Motorized Microinjectors can inject small volumes at fixed speed
reproducibly and precisely with control via foot switch. This is
important especially in controlled experiments where the results of
different injections need to be comparable. Another advantage of
motorized microinjectors is that they minimize vibrations. These
injectors range from a simple economical one-function model to a
multi-functional model which includes remote control, separate
injection pressure, holding pressure, and filling pressures.
