20100190215 | PENETRABLE CAP - A cap having a core structure dimensioned to receive a pipette therethrough. The cap includes two axially aligned frangible seals that are affixed to the core structure in a spaced-apart relationship. The frangible seals include a foil layer and are constructed so that air passageways are formed between the frangible seals and a pipette tip when the pipette tip penetrates the frangible seals. The cap optionally includes a filter interposed between the first and second frangible seals. | 07-29-2010 |

20080245163 | PENETRABLE CAP HAVING RIB STRUCTURES - A cap having a plurality of rib structures situated on an inner wall of the cap to facilitate the formation of air passageways as the cap is penetrated by a pipette tip. The air passageways aid in venting air from a fluid-holding vessel closed with the cap. | 10-09-2008 |
20090036327 | Method for chemical treatment of porous silicon surface - A method which renders the 3D surface of the insides of the pores of porous silicon biochip appropriate for conducting studies on biomolecule interactions without labels. | 02-05-2009 |
20090081694 | Modified well plates for molecular binding studies - Microtiter plates modified to permit their use for molecular binding studies. | 03-26-2009 |
20090098567 | COLLECTION DEVICE - A cap which can form an essentially leak-proof seal with an open-ended vessel capable of receiving and holding fluid specimens or other materials for analysis. To minimize potentially contaminating contact between a fluid sample present in the vessel and humans or the environment, the present invention features a cap having a frangible seal which is penetrable by a plastic pipette tip or other fluid transfer device. The cap further includes a filter for limiting dissemination of an aerosol or bubbles once the frangible seal has been pierced. The filter is positioned between the frangible seal and a retaining structure. The retaining structure is positioned on the cap above the filter and may be used to contain the filter within the cap. The material of the retaining structure may be penetrable by a fluid transfer device. | 04-16-2009 |
20090208966 | METHOD FOR REMOVING A FLUID SUBSTANCE FROM A CLOSED SYSTEM - A cap which can form an essentially leak-proof seal with an open-ended vessel capable of receiving and holding fluid specimens or other materials for analysis.

20100277725 | UNIVERSAL MULTIDETECTION SYSTEM FOR MICROPLATES - An apparatus and a method for optically analyzing a sample are provided. The apparatus includes a first optical device that transmits a narrow waveband of light and has a first filter and a first monochromator that provide different paths for the narrow waveband of the light. The apparatus may also include a light source that generates the light as broadband excitation light, in which case the first optical device transmits a narrow waveband of the broadband excitation light through the first filter or the first monochromator. Further, the apparatus may include a second optical device that directs the narrow waveband of the broadband excitation light onto the sample and receives emission light from the sample, a third optical device that transmits a narrow waveband of the emission light, and a detector that converts the narrow waveband of the emission light into an electrical signal. | 11-04-2010 |
