This kit is packaged as a cost effective alternative to the 1243-1000 Water Toxicity Kit. Bacterial reagents are packaged to permit less reagent waste for smaller sample numbers. The operation protocol has also been simplified to reduce pipetting steps and a salt tablet is included instead of OAS solution and sample diluent to reduce costs in shipping. Results can be interpreted by any luminometer.
1. 1243-505 – Freeze dried Aliivibrio fischeri reagent vials x 6 (each vial can accomodate 24 toxicity determinations).
2. 1243-510 – 6 bottles of diluent (12 mL), sufficient to reconstitute all reagents.
3. 1243-515 – 1 x 9.0g NaCl salt tablet (preparation of OAS and sample diluent in situ)
ISO 11348-3: Water quality – Determination of the inhibitory effect of water samples on the light emission of Vibrio fischeri (luminescent bacteria test).
ISO 21338:2010 Water quality — Kinetic determination of the inhibitory effects of sediment, other solids and coloured samples on the light emission of Vibrio fischeri (kinetic luminescent bacteria test)
The BioTox™ reagents perform comparably to several similar commercial test systems (Microtox, LumiStox, ToxAlert) when conducted according to the ISO standards mentioned above. The test organisms are extremely sensitive to organic contaminants and show excellent correlation with toxicity assessments performed with other aquatic species like the fathead minnow and Daphnia magna.
