Patent number: 7807054Abstract: The present invention relates to a chromatography column that removes the longitudinal load from the column tube altogether and transfers it to a yoke and stanchion arrangement situated around but external to the column tube. By using the yoke/stanchion system, the central adjuster can be used to move the top end into and out of the housing. Thus, when internal pressure is applied to the column, the tube experiences no longitudinal load. Additionally, the yoke and stanchion design allows for complete removal of the end from the tube without cumbersome disassembly. Moreover, the yoke provides a place to retain the end while the tube is being filled, emptied, cleaned or repaired.Type: GrantFiled: November 19, 2008Date of Patent: October 5, 2010Assignee: Millipore CorporationInventors: John Graham Dunkley, Neil Francis Frazer, Melvyn John Gill

Patent number: 7578934Abstract: A seal on a movable top or bottom plate for use in a chromatography column. The plate is formed of a flow distributor connected to one or more movement rods that control the movement of the top plate within a chromatography column. The plate is formed of two pieces, a flow distributor and a seal plate. The seal plate is mounted on top of the flow distributor and has a seal that is essentially co-terminal with the outer edge of the flow distributor. The seal plate is attached to the flow distributor by one or more pins or threaded bolts and forms a space between them. The one or more pins contain one or more compression means for biasing the seal plate against the flow distributor. An opening is formed in the seal plate for the selective introduction of a pressurized energy source such as compressed air, gas or hydraulic fluid into the space to overcome the compression means. One or more seals are arranged between the seal plate and distributor to maintain the pressurized energy source between the two of them.Type: GrantFiled: October 11, 2005Date of Patent: August 25, 2009Assignee: Millipore CorporationInventors: Melvyn Gill, Neil Francis Frazer, John Graham Dunkley, Geoff Purdom
