A device for simultaneously dispensing a solution containing a sample to a test device and aspirating the sample from the device. The invention includes obtaining a sample of the cellular population and initiating a reaction between a metabolic component of the cellular population and a bioreporter. The process clusters include various associated processes that are made compliant with a predefined set of standards. Alternate embodiments include optional sensors such as a flowmeter, compass, tiltmeter, depth gauge and diver techniques to compensate for navigational errors due to a water current pushing a dive flagfloat away from a diver.
