QUANTOFIX® test strips meet all requirements of a modern rapid test. The colour of the reactive pad changes depending on the concentration of an analyte in the sample. The evaluation is usually carried out visually by comparison of the reaction colour with a multi-stage colour scale. These test strips are immediately ready-to-use. They do not require additional accessories. The test strips are intended for single use, maintenance or calibration are not required.

Supplier: MACHEREY-NAGEL

These quantitative filter papers are made from refined pulp and linters. They are purified in a highly developed clean-up process to remove organic and inorganic impurities. This ensures a low ash content of <0,01 %. They are consistent performance and give safe results in gravimetric analyses.
