Capillary pumps for autonomous capillary systems.
Autonomous capillary systems (CSs), where liquids are displaced by means of capillarity, are efficient, fast and convenient platforms for many bioanalytical applications. The proper functioning of these microfluidic devices requires displacing accurate volumes of liquids with precise flow rates. In this work, we show how to design capillary pumps for controlling the flow properties of CSs. The ...
متن کاملAnalysis of Flow Rate Through Elastomeric Local Infiltration Analgesia Pumps
Background: Local infiltration analgesia pumps have been increasingly used to provide postoperative pain relief. However, their flow rate over time may not be reliable and accurate which can pose concerns regarding the achievement of the desired therapeutic level. We sought to find out in vitro if the flow rate of two elastomeric infusion pumps when combined with two types of wound catheter is ...
متن کاملModels for Flow Rate Simulation in Gear Pumps: A Review
Gear pumps represent the majority of the fixed displacement machines used for flow generation in fluid power systems. In this context, the paper presents a review of the different methodologies used in the last years for the simulation of the flow rates generated by gerotor, external gear and crescent pumps. As far as the lumped parameter models are concerned, different ways of selecting the co...
متن کاملElectroosmotic flow pumps with polymer frits
Electroosmotic flow (EOF) pumps with flow rates on the order of 1 ml/min have been designed and fabricated. These pumps use EOF to propel liquid solutions in a compact system with no moving parts. The pumping chamber is filled with densely packed non-porous silica particles, and the particle bed is held in place using two polymeric porous frits. The pump frame is made of acrylic, the frits are ...
متن کاملSweeping capillary electrophoresis: a non-stopped-flow method for measuring bimolecular rate constant of complex formation between protein and DNA.
We introduce sweeping capillary electrophoresis (SweepCE), a non-stopped-flow method for directly measuring the bimolecular rate constant of complex formation, and demonstrate its use for studying protein-DNA interaction. The capillary is prefilled with a solution of DNA, and electrophoresis is then carried out from a solution of the protein in a continuous mode. Because the electrophoretic mob...
