20120216633 | Sample Tubes for Use in Automated Systems and Methods of Manufacture - One or more embodiments of the invention are directed to sample tubes comprising a cylindrical elongate tube having a gripping section with at least one discontinuity extending radially about the outside surface of the elongate tube. Methods of making sample tubes and their use in sample handlers are also described. | 08-30-2012 |
20120194194 | NMR Sample Containers - A kit and methods of using including a package with at least one NMR tube comprising an elongate cylindrical body with an open proximal end and a band around an outside of the cylindrical body, the band positioned adjacent the open proximal end and having a width extending along a length of the elongate cylindrical body. The kit also including at least one closure configured to slidably engage the outside of the elongate cylindrical body so that when the closure is fully placed on the NMR tube, a distal end of the closure extends a length along the cylindrical body and is within about the width of the band. | 08-02-2012 |
20110185826 | Sample Tubes for Use in Automated Systems and Methods of Manufacture - One or more embodiments of the invention are directed to sample tubes comprising a cylindrical elongate tube having a gripping section with at least one discontinuity extending radially about the outside surface of the elongate tube. Methods of making sample tubes and their use in sample handlers are also described. | 08-04-2011 |
20090128151 | Closure and System for NMR Sample Containers - A selectively removable closure for closing the open end of an NMR sample tube having an open end and a closed end of the invention includes a cylindrical proximal first and a distal second portion, both portions substantially congruent to a central axis. The second portion has a hollow bore extending therethrough, the hollow bore has three sections: a distal section, a central section and a proximal section. The distal section has an inside diameter sized to accept the outside diameter of a preselected size NMR sample tube substantially without an interference, the central section is sized to provide a compliant interference fit with the outside diameter of the preselected size NMR sample tube, and the proximal section is sized to accept the outside diameter of the preselected size NMR sample tube without interference. As a user inserts the open end of the NMR sample tube axially into the closure, the distal section guides the tube into the closure, the central section provides a user perceptible resilient resistance to the passage of the tube and the movement of the tube open end into the proximal section allows the user to perceive a lessened resistance to the movement of the tube followed by seating the tube open end against the first portion of the closure. | 05-21-2009 |
