Abstract

Precigenome Pressure and Flow Controller and its Applications

Chen Li, Vice President of R&D, Precigenome, LLC

We will present a multiple channel (4 or 8 channels) pressure and flow controller based on our proprietary technology. This portable controller can provide pulseless accurate pressure and vacuum (<0.1% of set value) in a fast response time (<2s) without outside pressure and vacuum source. The controller can also connect to flow sensors (optional feature) and use feedback loop to monitor flow rates and control pressures to obtain constant flow rates. The controller has many applications on microfluidic field. One of applications is to generate micro droplets in microfluidic chips. We developed a droplet generator based on our pressure control technology. In this presentation, we will also present several applications co-developed with our customers using our droplet generators, such as sample preparation for next generation sequencing and rare cancer cell detection.
