| 20120076708 | POROUS SEALING MATERIAL - A porous article of manufacture (a sealing material) which comprises sintered hydroxyalkylcellulose, for example, sintered hydroxypropylcellulose, or a sealing material which is capable of being formed into a porous article in the form of a filter and which is made by heating at least one gelling agent that has carboxyl functionality and at least one gelling agent that has hydroxyl functionality, preferably carboxylmethylcellulose (CMC) and hydroxypropylcellulose (HPC) respectively, and a method for preparing the same from a powdery admixture thereof, and a pipette which includes the sealing material in the form of a filter, and also including embodiments of a bilayer filter and of a trilayer filter, each of which comprises a composite of a filter of the present invention and a filter comprising porous sintered polyethylene, preferably ultra high-molecular weight polyethylene. | 03-29-2012 |
| 20120156114 | FILTER PIPETTE TIP - Filter pipette tip with a small tube with a relatively large aperture at one end for attaching to a pipette, a relatively small aperture at the other end for the passage of liquid and a through-channel between the large aperture and the small aperture and a porous filter arranged in the through-channel, filling up a portion of the through-channel and comprising at least two layers arranged in series in the direction of the through-channel of which a fine-pore layer has a pore size of a maximum of approximately 20 μm and a coarse-pore layer a pore size of approximately 20 to 50 μm, the two layers having different pore sizes. | 06-21-2012 |
| 20120308445 | DISPENSER WITH FILTER DEVICE - A biological processing system includes a platform assembly for holding slides and a dispenser assembly with dispensers. The dispensers are sequentially positionable over specimen-bearing slides to enable dispensing of substances onto specimens. The dispensers include a filter device for filtering a processing substance such that a substantially precipitate free filtrate is applied to the specimens. The dispenser includes a filter device positioned at least partially in a reservoir chamber. The filter device includes anti-clogging features to maintain desired performance. | 12-06-2012 |

| 20140050635 | AUTOMATIC DEVICE FOR THE SYNTHESIS OF PEPTIDE-BASED RADIOACTIVE DRUGS FOR DIAGNOSTIC AND/OR THERAPEUTIC USE - Device for the synthesis of peptide-based radioactive drugs, for diagnostic and/or therapeutic use, includes: a frame; a closing case for the frame; a first disposable main module; a second disposable module, slidingly associated with the first module; a third disposable test-tube holder module, reversibly fixable to the frame ( | 02-20-2014 |
| 20140134077 | SAMPLE LIQUID INJECTION TOOL AND SAMPLE LIQUID HEAT TREATMENT APPARATUS - There is provided a sample liquid injection tool including a reservoir section configured to store a sample liquid, a channel having one end protruding from an outer surface and configured to discharge the sample liquid therein from a protrusion end to an outside, and a heating unit and a filter installed between the reservoir section and the channel to enable passage of the liquid. | 05-15-2014 |
| 20140377147 | CHROMATOGRAPHY PIPETTE TIP - Chromatography pipette tip having a first vessel and a second vessel which is open at two opposite ends and which, in each instance, has a bottom orifice via which a sample liquid can either be sucked in or expelled. The two vessels are fluidically and sealably connected to one another. A reaction matrix is arranged in one of the two vessels, through which reaction matrix the sample liquid is pushed by means of a pipettor to which the chromatography pipette tip is connected when used as intended. The sample liquid is drawn in and dispensed in opposite directions by the chromatography pipette tip and flows through the reaction matrix only in one direction. | 12-25-2014 |
