1. A method for monitoring a sample handling process, comprising:
- associating a liquid sample with a pipette tip;
performing the sample handling process with the liquid sample with respect to the pipette tip, the sample handling process including aspirating or dispensing of the liquid sample with respect to the pipette tip;
using a machine vision system to acquire a 2-dimensional image of at least a portion of the pipette tip before, during or after performance of the sample handling process; and
storing the acquired image to allow verification of a presence or absence of a clot associated with the liquid sample during aspirating or dispensing of the liquid sample.

Abstract
A sample processing apparatus has an associated machine vision system. The vision system may acquire an image of at least one fluidic chamber, which can be analyzed by the machine vision system and/or stored. The image and/or analysis of the image may provide a record of the actions of the sample processing apparatus, which permits a user to verify proper operation of the sample processing apparatus.

8. A sample handling apparatus, comprising:
-
at least one pipette tip adapted to hold a liquid sample and allow for aspirating or dispensing of the liquid sample relative to the pipette tip; and a machine vision system having an image acquisition device positioned to acquire a 2-dimensional image of at least a portion of the pipette tip, the machine vision system being adapted to allow verification of a presence or absence of a clot associated with the pipette tip and the aspiration or dispensing of the liquid sample relative to the at least one pipette tip based on the image. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
