Heavy Metal Sensors

Sensors and Kits
Each disposable color-coded sensor is designed for a specific heavy metal test target. Kits provide sampling tubes, syringes and cuvettes. Sensors, supplies and fluorimeter are also sold separately.  ANDalyze’s proprietary Catalytic DNA sensors use a DNAzyme reaction mechanism that fluoresces in the presence of a target contaminant substance such as lead. The fluorescence of the reaction is measured to determine the toxicity of the target heavy metal and is reported in parts per billion (ppb).

To help differentiate the materials specific to each analyte, the packaging has been individually labeled and the sensor housings and buffer caps have been color coded.
