Dolomite announces that is has recently launched Mitos P-Pump, that provides a pulseless liquid flow, using a precise pressure driven pumping mechanism.
The company says that, with excellent response time and accuracy, this pressure driven flow is ideal for microfluidic systems where a highly stable flow is required. This includes applications such as compartmentalized chemistry and alginate polymerization, which necessitate the stable formation of oil-in-water or water-in-oil droplets; however their monodispersity (size consistency) is key to obtaining accurate and repeatable results.
Dolomite has therefore carried out a number of tests to compare the size consistency of droplets formed by the Mitos P-Pump with market leading syringe pumps. Droplets of water-in-oil were generated on a 100µm sized X-Junction, using each of the pump technologies. The droplet diameter from a continuous stream was measured using image analysis software.
The resulting data demonstrated that the Mitos P-Pump provides a coefficient of variation in the droplet diameter of less than 0.6%, compared with 5.5% for the leading syringe pump. Its precise pressure-driven pumping mechanism delivers liquid with a smooth and even flow, whereas even the best motor drives and mechanics of a syringe pump have slight non-linearities, which cause unwanted pulsation. The Mitos P-Pump technology therefore provides the best solution for droplet formation applications.
