DEVICE FOR EXTRACTION OF A PARTIALLY DEFINED SAMPLE VOLUME FROM A LARGER VOLUME
First Claim
1. A device for extraction of a partial defined sample volume from a larger liquid sample volume comprising a) a body having a reference surface and b) a measuring cavity extending from a part of the reference surface into the body, thereby forming at least one opening plane substantially uniform with the reference surface, the cavity having a defined volume below said opening plane in said reference surface, the body being adapted for reception of an excess sample volume at the cavity and elimination of sample above the reference surface to leave in the cavity a measured sample volume having said defined volume, said device comprising an information carrier, applied to or arranged for distribution with the device, having direct or indirect volume information about the defined volume established for the cavity.

Abstract
The invention provides a device for extraction of a defined sample volume from a larger sample volume. The device includes a body having a reference surface and a measuring cavity extending from a part of the reference surface into the body, thereby forming at least one opening plane substantially uniform with the reference surface, the body being adapted for reception of an excess sample volume at the cavity and elimination of sample above the reference surface to leave in the cavity a measured sample volume having the defined volume. An information carrier is applied to or arranged for distribution with the device, having direct or indirect volume information about the defined volume established for the cavity. The invention also relates to a method for determining the volume of such a cavity, to a set of at least two such devices, to a method for dilution of at least two liquid samples by the use of at least two such devices, to an analytic instrument, to a method for operating such an instrument, to a system including the device and the instrument, and to a method for operating the system.

25. A method for determining the volume of at least one cavity, and optionally further cavities, arranged for extraction of a partial defined sample volume from a larger liquid sample volume, the one cavity, and optional further cavities each, being arranged in a device comprising a) a body having a reference surface and b) a measuring cavity extending from a part of the reference surface into the body, thereby forming at least one opening plane substantially uniform with the reference surface, the cavity having a defined volume below said opening plane in said reference surface, the body being adapted for reception of an excess sample volume at the cavity and elimination of sample above the reference surface to leave in the cavity a measured sample volume having said defined volume, in said method comprising:
measuring a volume corresponding to the cavity confined by the opening plane and body surfaces surrounding the measuring cavity to obtain a measured volume value and deriving an established volume value from the measurement. - View Dependent Claims (29, 30, 35, 36, 38, 39)
