20110038769 | Method and Device for Sample Preparation - The invention provides extraction columns for the purification of an analyte (e.g., a biological macromolecule, such as a peptide, protein or nucleic acid) from a sample solution, as well as methods for making and using such columns. The columns typically include a bed of extraction media positioned in the column, often between two frits. In some embodiments, the extraction columns employ modified pipette tips as column bodies. In some embodiments, the extraction columns are comprised of frits having a low pore. In some embodiments, the frits of the extraction columns have a pore volume of less than one microliter or less than 10% of the interstitial volume of the bed of extraction media. | 02-17-2011 |

20100316542 | PIPETTE TIP - The present invention is to present a disposable pipette tip used in a dispensing device, comprising: an attachment section for being attached to the dispensing device; and a liquid containing section for containing a liquid aspirated by the dispensing device, which is continually located to the attachment section and comprises a first part and a second part being continually located to the first part on the attachment section side, wherein the first part comprises a tip portion, an intermediate portion and a stepped portion, the tip portion including a distal end of the pipette tip, the intermediate portion continually located to the tip portion and the second part, the tip portion having an external diameter that decreases toward the distal end, and the intermediate portion having an external diameter that decreases toward the tip portion; the stepped portion is formed at a connecting position of the tip portion and the intermediate portion such that the external diameter of the intermediate portion at the connecting position is larger than that of the tip portion at the connecting position, the connecting position being closer to the distal end than the second part; the second part has an internal diameter that decreases toward the first part; the external diameter of the intermediate portion at the connecting position is larger than the internal diameter of an end of the second part on the first part side; the external diameter of the tip portion at the connecting position is smaller than the internal diameter of the end of the second part on the first part side; and length from the end of the second part on the first part side to the end of the attachment section on the opposite side of the second part is not less than twice but not more than four times as large as that of the tip portion. | 12-16-2010 |
20110076205 | Pipette Tip Mounting Shaft - A pipette tip mounting shaft includes outwardly circumferentially extending locking lobes over which the pipette tip collar is mounted. The locking lobes preferably include an inclining ramp portion that gently flexes and distorts the pipette tip collar out-of-round as the mounting shaft is inserted into the pipette tip, rather than the stretching tip collar. Each locking lobe also includes a declining ramp portion which extends upward along the mounting shaft. The peak of the lobes is preferably curved. When the pipette tip is fully mounted on the mounting shaft, a locking ring on the inside surface of the tip collar engages the declining ramp of the lobes to provide an over-center engagement, however, the required ejection force is small. | 03-31-2011 |
20120121483 | MULTICHANNEL PIPETTE - The invention relates to liquid dispensing and concerns a multichannel pipette, which comprises on its lower tip a shelf in the transverse direction of the tip and to which lower tip a pipette tip can be attached, which pipette tip comprises at least one longitudinal claw, whereby when the pipette tip is in its place, the point of the claw is above the shelf. Each cylinder is connected with a claw opening comprising an opener so that by pressing the opener downwards the claws can be turned outwards off the shelf. The opening mechanism further comprises an organ resilient in the longitudinal direction. In accordance with the invention, the tip removal is made to function reliably, even if there were significant differences in the dimensioning of the opening constructions of the lower tips. | 05-17-2012 |
20120213677 | PIPETTE AND SEALING TIP - A sealing pipette tip includes features to seal the tip directly against the piston in an air displacement pipette, avoiding the need for a piston seal within the pipette. This configuration reduces potential points of failure, allows the pipette-tip interface to be optimized, and improves liquid handling characteristics of the pipette. | 08-23-2012 |
