Pipette test measures hydrogen peroxide in H₂O₂ for solutions, bleaching solutions and washing solutions.
LCW058 pipette test (13mm) measures 1-10 g/L H₂O₂ for solutions, bleaching solutions and washing solutions. The product uses peroxomolybdate method. Article LCW058 can be used for 40 tests. The product is compatible with the following DR series instruments: DR3900 and DR6000. Pipette test is intended to be used together with LCW906 cuvettes.
Insert the standard cuvette in the spectrophotometer and push ZERO. Mix 5.0 mL solution A and 0.2 mL sample in the LCW906 cuvette. After that close the cuvette and invert the cuvette content several times. After 2 minutes, thoroughly clean the the outside of the cuvette, insert the cuvette into the cell holder and push READ. Hydrogen peroxide and peracetic acid enter into reaction with molybdates forming yellow peroxomolybdates that should be analyzed photometrically. Perform the plausibility check on testing results (dilute and/or spike the sample).
The product must be stored refrigerated at the temperature between 2 °C and 8 °C.
