Patent number: 10656060Abstract: Fluid containment pressure vessel that eliminates the outer support housing present in certain conventional vessels, and provides an improved cap-to-body interface. In certain embodiments, the cap is threaded and configured to threadingly engage with the body of the pressure vessel, and has sufficient structural integrity to withstand the pressures in the device without the need for a support housing. In certain embodiments, an interlock mechanism is provided that prevents the cap from being opened (e.g., removed from the body) while the device is under pressure. In certain embodiments, a pressure relief valve is provided with a pre-loaded biasing mechanism to achieve the required pressure release rate. The vessel can be used for sample preparation, including purification or concentration of samples, particularly protein samples.Type: GrantFiled: August 29, 2018Date of Patent: May 19, 2020Assignee: EMD Millipore CorporationInventors: Phillip Clark, Kurt Greenizen, John Doyle

Patent number: 9897520Abstract: Sample preparation device that allows for a complete bind, wash, elute, buffer-exchange and concentration process to be carried out without sample transfer between multiple devices. The device includes a reservoir, a column for holding chromatography media, a holder region for holding a filtration device, and an outlet. The filtration device plugs into the holder region of the centrifugal device, and the assembly can be placed in an optional holder. The assembly, with or without the optional holder, can be placed in a conventional centrifuge tube for centrifugation. The entire bind, wash, elute, buffer exchange and concentration steps can be carried out with the apparatus without any pipette transfers (and the associated sample losses. The sample preparation device also can be used for binding and washing steps, in which case the filtration device is not needed, and for buffer exchange and concentration steps, in which case the media is not needed.Type: GrantFiled: December 18, 2015Date of Patent: February 20, 2018Assignee: EMD Millipore CorporationInventors: Christopher A.

Patent number: 9295947Abstract: Filtration device suited for concentration of liquid samples, particularly biomolecules, and a method of concentrating, desalting, purifying and/or fractionating liquid samples. In certain embodiments the device includes a housing having a sample reservoir, and two substantially vertically oriented and spaced apart membranes disposed in the housing. An underdrain is associated with each membrane such that fluid passing through each membrane flows through a respective underdrain into a filtrate collection chamber. The fluid that does not pass through the membrane is collected in the retentate collection chamber, and can be recovered such as by a reverse spinning step, achieving recoveries greater than about 90%. The substantially vertical orientation of the membranes increases the available membrane area by at least 2.7 times the area available in a conventional filter device.Type: GrantFiled: February 26, 2014Date of Patent: March 29, 2016Assignee: EMD Millipore CorporationInventors: Louis Bonhomme, John Doyle, Kurt Greenizen, George Gagne, Sean Devin, Gerard Lombard, Vincent Smith
