A system for extracting analytes from a biological sample, which includes: an electronic pipette having pipette cones with a tip; a well support; a pipette holder including: a base which can removably house each well support; a pipette support into which the pipette is inserted, and which can move relative to the base between a first position in which the tips of the cones are inserted in a well of the support and at least one second position in which the tips are outside the wells; a housing facing the pipette cones above their tip when the pipette support is in the first position, and facing the tips of the pipette cones when the pipette support is in the second position; and a magnetized part removably inserted in the housing.

The present invention relates to an automated analytical system and an automated method for separating and detecting an analyte, as well as an automated analytical instrument.

This invention relates to methods, systems, and computer program products for verifying dispensing of a fluid from a pipette.

Specimen delivery device for the delivery of a liquid sample to be analysed comprising: a proximal end, and a distal end. The distal end being longitudinally displaced from the proximal end of the device. The device comprises a base at the proximal end for releasable connection to a magnetic sample holder of a liquid sample analysis device. The device further comprises a longitudinally extending projection having a radial inner portion, the projection extending from the base towards the distal end, the projection being arranged for receiving and holding a sheath. The device comprises at least one fluidic conduit, the fluidic conduit extending at least partially longitudinally within the radial inner portion, the fluidic conduit for the delivery of a liquid sample for analysis.

Devices and methods for performing pre-analysis sample processing of biological and chemical samples using robotic liquid handlers are disclosed. Methods for solid phase extraction, protein precipitation and filtration of biological and chemical samples using automation and the devices in a rapid and convenient way are described.

A system for loading pipette tips. A system for accommodating pipette tips is provided, comprising a tray having openings for accommodating pipette tips in a plate, wherein the openings have at their upper end a surrounding contour which has curved surface area corresponding to a section of a spherical washer, and pipette tips having at their upper end an offset forming a contact surface for the surrounding contour of the tray's opening, wherein the shape of the contact surface corresponds to the section of a spherical washer so that the centers of both spheres of surrounding contour and contact surface are congruent

An adapter for connecting an array of pipette tips having through bores with conical upper ends to a multichannel air displacement pipettor having a plurality of ports with compliant internal sealing surfaces. The adapter comprises a planar base with an array of openings extending between its top and bottom surfaces. Sealing tubes project upwardly from the top surface, and tip mounting tubes project downwardly from the bottom surface, with pairs of sealing tubes and tip mounting tubes being arranged coaxially and in communication with respective ones of the openings in the base. The tip mounting tubes are externally dimensioned and configured for insertion into the conical upper ends of the pipette tips, and the sealing tubes are externally configured and dimensioned for insertion into the ports of the pipettor and into sealing interengagement with their compliant internal sealing surfaces.

A pipette tip according to certain embodiments includes a proximal end, a distal end, and a reagent chamber. The proximal end is dimensioned to fit on an end of a pipettor, and includes a proximal end opening. The distal end includes a distal end opening. The reagent chamber has a reagent composition disposed therein. The reagent chamber is defined at least in part by a proximal barrier and a distal barrier. The reagent composition is operable to pass through the distal end opening upon rupturing of the distal barrier.

A pipette tip system for use with a plurality of pipette tips is disclosed that includes a support card and a support card lid. The support card includes an array of pipette tip receiver openings arranged in a N×M array, wherein the N is less than M. The support card further has a short-side card rail edge on an edge of the support card along the N side of the array, and a long-side card rail edge on an edge of the support card along the M side of the array. The support card lid includes a long-side lid rail edge extending from a support card first surface, which is adapted to slidably mate with the long-side card rail edge, and a short-side lid rail edge extending from a support card second surface, which is adapted to slidably mate with the short-side card rail edge.

The present invention provides a pipette tip, which can be used in in-vitro diagnostics, in particular in the diagnostic testing of body fluids, such as in coagulation testing. The Pipette tip contains two constituents in a spatially separated manner. The present invention furthermore provides a method of performing such diagnostics, e.g. coagulation analysis, and to the use of the pipette tip in such diagnostic testing.
