Intelligent Flow Control Improves Performance of Dolomite Microfluidic Device

Published on July 5, 2012 at 8:31 PM

Microfluidics expert Dolomite has enhanced its world leading Mitos P-Pump range with the introduction of intelligent closed-loop Flow Control which provides unparalleled control of flow rates from 70 nl/min to 5 ml/min.

The improved flow rate precision of the new software benefits the fields of droplet generation, micro process engineering and microreaction kinetics.

By connecting a Mitos Flow Rate Sensor in-line between the pump and microfluidic device, users can enter a flow rate target directly on the Mitos P-Pump itself with no need for a PC. Systems can be extended to multiple P-Pumps, which will all control flow rate independently. Featuring quick changeover between flow control and pressure control, users can continue to enjoy the outstanding flow smoothness of the pressure driven Mitos P-Pump, but with even more accurate control over the delivery of picolitre reagent volumes into the system.

Operating in flow control mode provides quantifiable benefits in droplet microfluidics. Dolomite's flow control software has set a new benchmark for droplet monodispersity with a CV < 0.14 % measured for the droplet size over long time periods.

The Dolomite Centre Limited

Established in 2005 as the world's first Microfluidic Application Centre, Dolomite focused on working with customers to turn their concepts for microfluidic applications into reality. Today, Dolomite is the world leader in solving microfluidic problems. With offices in the UK and US and distributors throughout the rest of the world, its clients range from universities developing leading-edge analytical equipment, to manufacturers of chemical, life sciences and clinical diagnostics systems.

Dolomite is pioneering the use of microfluidic devices for small-scale fluid control and analysis, enabling manufacturers to develop more compact, cost-effective and powerful instruments. By combining specialist glass, quartz and ceramic technologies with knowledge of high performance microfluidics, Dolomite is able to provide solutions for a broad range of application areas including environmental monitoring, clinical diagnostics, food and beverage, nuclear, agriculture, petrochemical, cosmetics, pharmaceuticals and chemicals. Furthermore Dolomite's in-house micro-fabrication facilities that include clean rooms and precision glass processing facilities allow to prototype and test all solutions rapidly which ensures a faster development cycle and reduces the time to market.
