Patent number: 11179725Abstract: A self-adhesive layered septum is disclosed. In one example, the septum includes a first outer layer including a thermoplastic elastomer such as a styrenic block copolymer, containing styrene ethylene butylene styrene (TPE-SEBS) capable of closing at least partially an aperture formed when a needle is inserted through the layer; an adhesive second layer for adhering the septum to a mouth area of a well or container to which the septum is attachable; and a thermoplastic third layer between the first and second layers, thermobonded to the first layer and providing better adherence for the adhesive layer. The first layer includes a recess and a vent, which reduce pressure differentials in use, but together with the third layer minimize evaporation through the septum.Type: GrantFiled: July 6, 2017Date of Patent: November 23, 2021Assignee: CYTIVA SWEDEN ABInventors: Hakan Erik Roos, Stefan Sjolander, Per Kjellin, Bharath Subrahmanya

Patent number: 9891192Abstract: A system and method for generating a digital image in fluorescence gel imaging is disclosed. The method includes providing a gel sample and placing the gel sample on a flat panel detector having array of photodiodes and transistors that collect light generated from the gel sample. The gel sample is illuminated using a light source integrated into the flat panel imaging system and light emitted by the gel sample responsive to an excitation of the gel sample by light provided by the light source is then collected, with the light emitted by the gel sample being collected by the array of photodiodes of the flat panel detector and converted to electric charges to generate light data. The light data is then processed to generate a digital image of the gel sample.Type: GrantFiled: May 15, 2014Date of Patent: February 13, 2018Assignee: GENERAL ELECTRIC COMPANYInventors: Feng Pan, Brian David Yanoff, Aaron Judy Couture, Hakan Erik Roos, Yu Zhao
