Microfluidic Pumps ExiGo is a precision syringe pump based on the 5-phase stepper motor drive that has more microsteps per revolution of the lead screw vs. standard syringe pumps on the market. ExiGo has 250,000 microsteps/ revolution and even at low rotational speed / low flow rates, it has a very low pulsation and high accuracy. When coupled with the flow sensor and active PID feedback; this results in very fast response times for changing flow rates. A standard syringe pump typically has a smaller number of microsteps and so usually the only way a standard “microfluidic” pump can achieve pulse-free flow control is to use small syringes; e.g. 0.5μL; 1μL; 5μL etc. to achieve non-pulsatile stable flow rates in the nanolitre/ minute range. By comparison, the ExiGo pump with the flow sensor can use a standard 250μL glass syringe to produce stable non-pulsatile flow rates of 10nL/min – 1ml/min; or a 5mL plastic syringe to produce stable non-pulsatile flow rates of 100nL/min – 20mL/min. ExiGo can be used in conjunction with expandable (flexible) element and fluidic resistance in order to dampen any pulsation occurring during the stepper motor operation. As it employs active feedback, the response time of the pumps still remains fast. Mirus is a precision syringe pump, which uses the combination of the expandable (flexible) element and fluidic resistance in order to dampen the pulsation of the syringe pump stepping. The main difference is that the ExiGo has feedback control; the Mirus does not. Because the Mirus does not have feedback control, it also does not have a fast reaction time and so takes a long time to change flow rates. Conversely due to the expandable element, the Mirus has a very stable flow profile. Additionally, Mirus is equipped with 3-way valve allowing automatic recharging and washout of syringe. Mirus is also provided with an 8-way flow splitter, allowing multiple executions(8 parallel experiments) simultaneously. Kima pump is a microfluidic pump designed to aid cell culture (e.g. endothelial cells) under physiological conditions (shear flow) in various biochips and flow chambers, including Cellix’s Vena8 Endothelial+ biochips where it is possible to culture 8 cell monolayers simultaneously over 24–48 hours. The pump is a solenoid pump and so it is not pulsefree. This pump delivers a preset volume of liquid as programmed.
