Download Programmable Syringe Flow Regulator

The syringe is similar to a piston pump. This type of pump has a piston
inside a cylinder-like container in which it serves as the pusher for the contents
of the liquid. This syringe plunger serves as the piston and its container serves as
the cylinder. According to the book entitled Biological Process Engineering,
“considering a piston accelerating within a cylinder, when it moves slowly, there
is hardly any pressure increase in the liquid ahead of the piston. The entire
column of the liquid moves within the tube at the same speed as the piston”
(Johnson, 1999). Taking into account that the syringe is closely similar to a
piston pump, it can be said that the statement above is applicable to syringe in
which the speed of diffusion or flow rate of the liquid is dependent on the force
applied in the plunger to the liquid. This nullifies the effect of viscosity of the
liquid.
