Light: Indicator and Predictor

In nature, bioluminescent plankton emit a visible blue-green light when they experience a shear force in the ocean. This force is usually a change in direction or pressure of the surrounding water. The phenomenon is accurately induced in the QwikLite® 200 Biosensor System.

During the stimulation process, the optical and electrical components measure bioluminescence of all the test samples for approximately 10-15 seconds and capture emitted light and specific wavelengths. There is always a control sample for each completed test.

The total amount of light produced is captured, measured and recorded by the optics and electronics of the instrument. The measurements are stored in a data file that can be immediately viewed, reviewed as a historical file, or downloaded to a PC or storage device via USB connector.

The six test samples are uniformly stimulated and measured in a matter of seconds. This patented technique allows the light measurement; bioluminescence, to be made uniformly with each disposable test kit. As a result, all samples are accurately and precisely measured. The data is gathered instantly.
