Delaware Patent of the Month – June 2023

Laboratory research and field experiments often involve precise dosage and dispensing of liquids, a task accomplished by pipettes and similar liquid dispensing devices. However, existing pipette technology presents limitations when it comes to dispensing liquid volumes across a wide range without sacrificing accuracy and precision. This drawback leads to cluttered work areas and increased costs, as researchers are forced to use multiple pipetting devices optimized for specific volume ranges.

Recognizing this need for a single, versatile pipetting device, inventor DeNovix, Inc has developed a more robust solution. Their recently patented multi-volume pipetting device employs nested plunger elements operating within distinct vacuum chambers to aspirate and dispense liquids accurately and precisely across a broad range of volumes. This innovative design enables seamless and rapid switching between low and high volumetric ranges, eliminating the need for multiple devices.

By intelligently manipulating the plunger elements, the device accurately dispenses liquid volumes within the desired range. The nested plunger design allows for precise control and reliable performance. The first and second liquid volume ranges can either have overlapping portions or distinct upper limits, providing flexibility for various experimental requirements.

The vacuum chamber system uses motors to actuate plungers, aspirating the desired liquid volumes by displacing air within the chamber. Dispensing is achieved by returning the plunger elements to the closed position.

DeNovix is a private biotechnology company formed in 2012. As scientists and engineers with proven track records of commercializing innovative products, we are passionate about facilitating the advances being made in today’s scientific community. Their products are designed with the aim of removing a barrier between new ideas and the limits of current technology.
