20080199365 | Planar registration of multi-well plate from well side - A multi-well plate such as a microtiter plate is secured from its well side in a manner that corrects or compensates for any deviations of the plate base from a planar configuration. This is achieved by an apparatus that includes an array of posts with exposed tips that define a plane, a plurality of movable collets that, when appropriately actuated, seize the walls of selected wells, and a biasing means to urge the collets in a direction that forces the wells of the microtiter plate against the exposed tips of the posts. | 08-21-2008 |
20090269835 | Thermal Cycler with Self-Adjusting Lid - A thermal cycling instrument for PCR and other reactions performed on multiple samples with temperature changes between sequential stages in the reaction procedure is supplied with a thermal block to provide rapid changes and close control over the temperature in each sample vessel and a pressure plate incorporated into a motorized lid that detects anomalies in the reaction vessels or in their positioning over the thermal block, and automatically adjusts the plate position to achieve an even force distribution over the sample vessels. | 10-29-2009 |
20100028988 | Microplates with Ultra-Thin Walls by Two-Stage Forming - A multi-well plate with wells having ultra-thin walls and yet with sufficient structural rigidity to allow reliable use of the plate in automated instrumentation is formed by first forming a plate blank by injection molding, the blank being of a thickness that provides the desired rigidity, and then subjecting the blank to vacuum forming to stretch designated areas in the blank to form wells or to extend wells already formed, the stretching resulting in a reduction in thickness of the molded resin at the walls of the wells only. | 02-04-2010 |
20100264030 | UNITARY ELECTRODE AND ELECTRODE SUPPORT FOR HORIZONTAL ELECTROPHORESIS - Horizontal electrophoresis is performed in a cell that includes a tank and a pair of electrodes, each mounted on an electrode support that is easily inserted into and removed from the tank, and once inserted, is secured in position by one or more spring-loaded, manual-release locking features. | 10-21-2010 |
20110211058 | COMPACT AUTOMATED CELL COUNTER - Biological cells in a liquid suspension are counted in an automated cell counter that focuses an image of the suspension on a digital imaging sensor that contains at least 4,000,000 pixels each having an area of 2×2 μm or less and that images a field of view of at least 3 mm | 09-01-2011 |
20120279954 | THERMAL CYCLER WITH SELF-ADJUSTING LID - A thermal cycling instrument for PCR and other reactions performed on multiple samples with temperature changes between sequential stages in the reaction procedure is supplied with a thermal block to provide rapid changes and close control over the temperature in each sample vessel and a pressure plate incorporated into a motorized lid that detects anomalies in the reaction vessels or in their positioning over the thermal block, and automatically adjusts the plate position to achieve an even force distribution over the sample vessels. | 11-08-2012 |
20130143272 | THERMAL CYCLER WITH VAPOR CHAMBER FOR RAPID TEMPERATURE CHANGES - Rapid and uniform temperature changes in the wells of a microplate or any thin-walled plate that contains an array of reaction wells or sample receptacles are achieved by the use of heating and cooling elements with a vapor chamber interposed between such elements and the microplate. The upper surface of the vapor chamber and the underside of the sample plate in certain embodiments are complementary in shape, i.e., they have identical but oppositely directed contours in the areas around each of the sample receptacles, to provide continuous surface contact along the surface of each receptacle. In other embodiments, an intermediary plate is placed between the vapor chamber and the well plate, with the top surface of the intermediary plate being complementary in shape to the underside of the well plate. | 06-06-2013 |
20140024107 | COMPACT AUTOMATED CELL COUNTER - Biological cells in a liquid suspension are counted in an automated cell counter that focuses an image of the suspension on a digital imaging sensor that contains at least 4,000000 pixels each having an area of 2×2 μm or less and that images a field of view of at least 3 mm | 01-23-2014 |
20140327757 | ADJUSTABLE DIGITAL MICROSCOPE DISPLAY - The present invention relates in general to microscopy systems. In particular, the present invention relates to microscopes rendering digital images of samples, with the capability to digitally control the focus of the microscope system, and the software used to control the operation of the digital microscope system. Further, the present invention relates to a microscope structure that allows for compact and multi-functional use of a microscope, providing for light shielding and control with samples that require specific light wavelength characteristics, such as fluorescence, for detection and imaging. | 11-06-2014 |
