How it works

The BioLight Toxy measures the light levels of the marine bacterium AliiVibrio fischeri, used in the BioLight reagent to determine the toxicity of a sample. Results are reported in % effect or EC50 (effective concentration 50%) dependent on the protocol and use of the portable or bench-top instrument.

Using the BioLight Toxy along with Aqua Science BioLight Multi or Single Reagents and consumables provides testing that can screen over 3,600 chemical compounds simultaneously, while also detecting synergistic toxicity effects.

The bacteria elicit the brightest light levels following reconstitution. These light levels are measured prior to sample exposure and over time after exposure to a sample, using a luminometer. The luminometer measures the changes in the light to indicate the levels of toxicity.
