20140199216 | LIQUID END ASSEMBLY FOR A MULTICHANNEL AIR DISPLACEMENT PIPETTE - A handheld multichannel air displacement pipette is modular in construction and includes compliant joints and molded plastic components in place of various machined metal, glass, and ceramic components found in traditional multichannel pipettes. These improvements are made without sacrificing performance in channel-to-channel consistency, accuracy, and precision. The multichannel pipette is inexpensive to manufacture, lightweight, reliable, and easy to assemble and service. | 07-17-2014 |
20130312545 | PIPETTE AND SEALING TIP - A sealing pipette tip includes features to seal the tip directly against the piston in an air displacement pipette, avoiding the need for a piston seal within the pipette. This configuration reduces potential points of failure, allows the pipette-tip interface to be optimized, and improves liquid handling characteristics of the pipette. | 11-28-2013 |

This configuration reduces potential points of failure, allows the pipette-tip interface to be optimized, and improves liquid handling characteristics of the pipette. | 08-23-2012 |
20100199789 | HYBRID MANUAL-ELECTRONIC PIPETTE - A hybrid manual-electronic pipette combines a manually driven piston with real-time electronic measurement of liquid volume and piston displacement while compensating for both pipette-specific and pipette model-specific variations. The hybrid nature of the pipette facilitates increased accuracy and improved ease of use, and enables additional functionalities not practicable with traditional manual pipettes. | 08-12-2010 |
20090104079 | Liquid end assembly for a handheld multichannel pipette with adjustable nozzle spacing - A handheld multichannel pipette includes multiple fluid-handling nozzles and a rotary adjustment mechanism for adjusting the width of a pattern of nozzles while maintaining equal spacing between pairs of nozzles. Embodiments of the adjustable-spacing multichannel pipette include an adjustable stop mechanism. | 04-23-2009 |
