Abstract
An apparatus for observation of magnetically labeled cells comprises an arrangement of magnets that are configured in confrontation across a horizontal gap. The magnets are further configured to produce a substantially uniform vertically-directed gradient in the gap. A sample vessel containing a fluid sample is positioned in the gap in order to allow the vertical gradient to cause collection of magnetically-labeled species on the interior upper surface of the vessel. The vessel is preferably transparent to allow observation of the collected species.
