ABSTRACT:
A non-invasive method of determining the level of fluid present in a test sample. The level of fluid present in a test sample in a container is determined by moving a pipettor toward the sample surface while aspirating air and monitoring the pressure change produced with a sensor. Non-homogeneity of the sample can be detected during the aspiration of the sample using the invention.
