We are looking to buy a pressure based flow control system and have quotations from Fluigent and Elveflow.
Fluigent system comprises of FLOW EZ with M-switch, manifold and flow sensor with standard accessories.
Elveflow quoted us their AF1 1600 system with MUX distributor, flow sensor, manifold and other standard accessories.
In our experiments we want to flow 3-4 solutions sequentially through a microfluidic geometry. We should be able to change flow rate for each solution and their should be no air gaps between different liquids when flowed through the channel.
I request you all to please suggest the better of the two alternatives?
