Abstract: A method for dissecting and collecting one or more cells from a tissue sample fixed to an inner surface of a microfluidic device is described. The tissue sample is in fluid communication with a channel having an inlet end and an outlet end defined by the microfluidic device. The method comprises flowing a first fluid through the channel with a fluid flow from the inlet end to the outlet end; powering a laser to direct laser energy into the channel to impinge upon the first fluid proximate a first region of the tissue sample and cause fluid cavitation to thereby ablate a first set of one or more cells from the tissue sample; and collecting the first set of one or more cells within a first sample container coupled to the outlet end.

Abstract: A centrifugal pump mounted in an external housing. The pump has a split housing containing an impeller with outwardly extending vanes that is mounted on a drive shaft. The drive shaft at one end is mounted to a sealed bearing within the external housing and at the other end to a drive.

Abstract: A centrifugal pump is provided for use with fluids, gases, and solids in connection with a drive shaft and a motor. The pump has a housing and at least a 30 degree sloped impeller mounted on the shaft within the housing. The housing has opposing inlet means on each side of the impeller and a discharge outlet. The impeller can be constructed as split through its center with an associated split housing or being an integral part.
